EXECUTIVE SUMMARY +================================================================================ + +BizHawk's main window menu system was migrated from WinForms ToolStrip/MenuStrip +controls to native Win32 MainMenu controls to resolve a critical accessibility +defect: NVDA screen reader could not announce menu items during keyboard +navigation, despite working correctly with mouse hover. + +The root cause is that WinForms ToolStrip controls do not fire the necessary +MSAA (Microsoft Active Accessibility) focus events during keyboard navigation +that screen readers rely on to track and announce the currently selected item. + +The solution replaces the ToolStrip-based menu with a native Win32 MainMenu, +which has built-in Windows accessibility support that correctly fires all +required accessibility events for both mouse and keyboard interaction. + +================================================================================ +2. ORIGINAL MENU IMPLEMENTATION ANALYSIS +================================================================================ + +2.1 ToolStrip/MenuStrip Architecture +------------------------------------ + +BizHawk's original menu implementation used the WinForms ToolStrip family of +controls, introduced in .NET Framework 2.0 as a replacement for the older +MainMenu control. The menu hierarchy was: + + MainForm + └── MainformMenu (MenuStripEx : MenuStrip) + ├── FileSubMenu (ToolStripMenuItemEx : ToolStripMenuItem) + │ ├── OpenRomMenuItem + │ ├── RecentRomSubMenu + │ │ └── [dynamically populated] + │ ├── SaveStateSubMenu + │ │ ├── SaveState1MenuItem ... SaveState0MenuItem + │ │ └── SaveNamedStateMenuItem + │ └── ... (other items) + ├── EmulationSubMenu + ├── ViewSubMenu + ├── ConfigSubMenu + ├── ToolsSubMenu + ├── [System-specific menus: NES, SNES, GB, etc.] + └── HelpSubMenu + +Key files: + - src/BizHawk.Client.EmuHawk/MainForm.Designer.cs (menu declarations) + - src/BizHawk.Client.EmuHawk/MainForm.Events.cs (event handlers) + - src/BizHawk.WinForms.Controls/MenuEx/MenuStripEx.cs + - src/BizHawk.WinForms.Controls/MenuEx/MenuItemEx.cs + +2.2 Custom Control Extensions +----------------------------- + +BizHawk extends the standard ToolStrip controls with custom classes: + +### MenuStripEx (MenuStripEx.cs) + +```csharp +public class MenuStripEx : MenuStrip +{ + [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] + public new Size Size => base.Size; + + [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] + public new Point Location => new Point(0, 0); + + [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] + public new string Text => ""; // PROBLEM: Empty text breaks accessibility + + [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] + public new string Name => Util.GetRandomUUIDStr(); // PROBLEM: Random names + + protected override void WndProc(ref Message m) + { + base.WndProc(ref m); + // Custom handling for WM_MOUSEACTIVATE to allow click-through + if (m.Msg == NativeConstants.WM_MOUSEACTIVATE + && m.Result == (IntPtr)NativeConstants.MA_ACTIVATEANDEAT) + { + m.Result = (IntPtr)NativeConstants.MA_ACTIVATE; + } + } +} +``` + +### ToolStripMenuItemEx (MenuItemEx.cs) + +```csharp +public class ToolStripMenuItemEx : ToolStripMenuItem +{ + [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] + public new Size Size => base.Size; + + [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] + public new string Name => Util.GetRandomUUIDStr(); // Random UUID each access + + public void SetStyle(FontStyle style) => Font = new Font(Font.FontFamily, Font.Size, style); +} +``` + +The `Name` property returning a random UUID on each access and `Text` returning +empty string were implemented to prevent the WinForms designer from serializing +these properties, but they have negative accessibility implications. + +2.3 Event Handling Model +------------------------ + +Menu item clicks are handled through standard WinForms event delegation: + +```csharp +// In MainForm.Designer.cs +this.OpenRomMenuItem.Click += new System.EventHandler(this.OpenRomMenuItem_Click); +this.SaveState1MenuItem.Click += new System.EventHandler(this.QuickSavestateMenuItem_Click); +``` + +Some handlers are shared across multiple items and determine the specific action +based on the sender: + +```csharp +// In MainForm.Events.cs +private void QuickSavestateMenuItem_Click(object sender, EventArgs e) + => SaveQuickSaveAndShowError(int.Parse(((ToolStripMenuItem) sender).Text)); + +private void QuickLoadstateMenuItem_Click(object sender, EventArgs e) + => LoadQuickSave(int.Parse(((ToolStripMenuItem) sender).Text)); +``` + +2.4 Rendering and Owner-Draw +---------------------------- + +The ToolStrip controls use custom rendering but NOT full owner-draw. They rely +on the ToolStripProfessionalRenderer or similar for visual styling. This is +important because full owner-draw can completely break accessibility, but +partial customization still allows some accessibility features to work. + +The WM_MOUSEACTIVATE handling in MenuStripEx allows the menu to be clicked +without stealing focus from the emulator - important for gameplay but +potentially interfering with accessibility focus tracking. + +================================================================================ +3. THE ACCESSIBILITY PROBLEM +================================================================================ + +3.1 Screen Reader Technology Overview +------------------------------------- + +Screen readers like NVDA (NonVisual Desktop Access) use multiple techniques to +determine what UI element is currently focused and should be announced: + +1. **MSAA (Microsoft Active Accessibility)** - Legacy API using IAccessible + interface and WinEvents for focus/selection notifications + +2. **UI Automation (UIA)** - Modern API with richer control patterns, but + requires explicit provider implementation for custom controls + +3. **Hit Testing** - Querying what's under the mouse cursor position + +4. **Focus Tracking** - Following EVENT_OBJECT_FOCUS and EVENT_OBJECT_SELECTION + events to know when focus moves between elements + +3.2 MSAA (Microsoft Active Accessibility) +----------------------------------------- + +MSAA works through two mechanisms: + +**IAccessible Interface:** +Controls expose an IAccessible COM interface that screen readers query for: + - accName: The accessible name (what to announce) + - accRole: The type of element (menu item, button, etc.) + - accState: Current state (focused, selected, checked, etc.) + - accDescription: Additional description + - accHitTest: What child is at a given screen coordinate + +**WinEvents:** +Applications call NotifyWinEvent() or the system fires events automatically: + - EVENT_OBJECT_FOCUS (0x8005): An object received keyboard focus + - EVENT_OBJECT_SELECTION (0x8006): Selection changed within a container + - EVENT_OBJECT_STATECHANGE (0x800A): An object's state changed + - EVENT_SYSTEM_MENUSTART (0x0004): A menu was activated + - EVENT_SYSTEM_MENUEND (0x0005): A menu was closed + - EVENT_OBJECT_INVOKED (0x8013): An object was invoked/activated + +Screen readers hook these events using SetWinEventHook() and respond by +querying the IAccessible interface of the source object. + +3.3 Why Mouse Navigation Works +------------------------------ + +When the user hovers the mouse over menu items, NVDA can announce them because: + +1. NVDA tracks the mouse cursor position +2. On mouse movement, NVDA calls AccessibleObjectFromPoint() or accHitTest() +3. This returns the IAccessible for the menu item under the cursor +4. NVDA queries accName and accRole to announce "Open ROM, menu item" + +This hit-testing approach works regardless of whether focus events fire, +because NVDA is actively polling based on cursor position. + +3.4 Why Keyboard Navigation Fails +--------------------------------- + +When the user navigates with arrow keys, NVDA announces nothing because: + +1. User presses Down Arrow in the menu +2. ToolStripMenuItem handles the key internally +3. The visual selection moves to the next item +4. **NO EVENT_OBJECT_FOCUS or EVENT_OBJECT_SELECTION is fired** +5. NVDA has no way to know the selection changed +6. NVDA remains silent + +The ToolStrip control family manages keyboard navigation internally without +notifying the accessibility system. This is a known limitation of WinForms +ToolStrip controls. + +3.5 Root Cause Analysis +----------------------- + +The fundamental issue is architectural: + +**Native Win32 Menus (HMENU):** +- The Windows shell/user32.dll directly manages menu display and navigation +- Built-in accessibility support fires all required WinEvents automatically +- EVENT_OBJECT_FOCUS fires as keyboard selection moves between items +- Works with all screen readers out of the box + +**WinForms ToolStrip Menus:** +- Implemented as custom .NET controls drawing in a ToolStripDropDown window +- Navigation is handled by .NET code, not the Windows menu manager +- No automatic WinEvent firing for selection changes +- IAccessible is implemented but not connected to focus event notifications +- Requires manual accessibility event firing, which is not implemented + +The ToolStrip architecture was designed for visual flexibility (owner-draw, +custom rendering, embedded controls) at the cost of native accessibility +integration. + +Additional contributing factors in BizHawk: + +1. **Random Name Property:** `Name => Util.GetRandomUUIDStr()` means + accessibility tools can't maintain stable references to controls + +2. **Empty Text Property:** `Text => ""` on MenuStripEx may confuse screen + readers expecting a menu bar name + +3. **Global Input Capture:** BizHawk uses RAWINPUT to capture keyboard input + at the driver level for emulator controls, which could theoretically + interfere with menu keyboard handling (though this was not the primary issue) + +================================================================================ +4. ALTERNATIVE SOLUTIONS CONSIDERED +================================================================================ + +4.1 MSAA Event Injection (NotifyWinEvent) +----------------------------------------- + +Attempted approach: Override selection-related methods in ToolStripMenuItemEx +to manually fire MSAA events: + +```csharp +[DllImport("user32.dll")] +private static extern void NotifyWinEvent(uint eventId, IntPtr hwnd, int objectId, int childId); + +private const uint EVENT_OBJECT_FOCUS = 0x8005; +private const uint EVENT_OBJECT_SELECTION = 0x8006; + +protected override void OnPaint(PaintEventArgs e) +{ + base.OnPaint(e); + if (Selected) + { + var parent = this.GetCurrentParent(); + if (parent != null) + { + NotifyWinEvent(EVENT_OBJECT_FOCUS, parent.Handle, -4, GetChildId()); + NotifyWinEvent(EVENT_OBJECT_SELECTION, parent.Handle, -4, GetChildId()); + } + } +} +``` + +**Why it failed:** The events fired but NVDA did not respond. This is because: +- The IAccessible implementation in ToolStrip may not correctly resolve the + child ID to the selected item +- NVDA may require specific event sequences or additional events +- The timing of events relative to internal ToolStrip state may be incorrect + +4.2 UI Automation Provider Implementation +----------------------------------------- + +Considered implementing IRawElementProviderSimple and related UIA interfaces +to provide modern accessibility support. + +**Why not pursued:** +- Requires significant implementation effort for all menu item types +- WinForms has limited UIA support requiring manual bridging +- Would need to implement multiple control patterns (Invoke, Selection, etc.) +- Testing and validation with multiple screen readers is complex + +4.3 AccessibleObject Customization +---------------------------------- + +Attempted using reflection to access the protected AccessibilityNotifyClients +method: + +```csharp +var method = typeof(Control).GetMethod("AccessibilityNotifyClients", + BindingFlags.NonPublic | BindingFlags.Instance); +method?.Invoke(parent, new object[] { AccessibleEvents.Focus, childIndex }); +``` + +**Why it failed:** Similar to direct NotifyWinEvent - the underlying IAccessible +implementation doesn't properly support the notification model that screen +readers expect for ToolStrip menus. + +4.4 Why These Approaches Failed +------------------------------- + +The core problem is that ToolStrip's accessibility implementation is incomplete +at a fundamental level. The IAccessible interface is present but: + +1. Child enumeration may not match actual visual selection state +2. Focus/selection events are not connected to internal navigation state +3. The accessibility tree structure may not accurately reflect the menu hierarchy + +Fixing this would require patching the .NET Framework's ToolStrip implementation +or completely replacing its IAccessible provider - both impractical approaches. + +================================================================================ +5. THE NATIVE MENU SOLUTION +================================================================================ + +5.1 Win32 MainMenu vs WinForms ToolStrip +---------------------------------------- + +The solution uses System.Windows.Forms.MainMenu, which wraps the native Win32 +HMENU menu system: + +| Aspect | ToolStrip/MenuStrip | MainMenu (HMENU) | +|---------------------|----------------------------|----------------------------| +| Rendering | .NET custom drawing | Windows shell native | +| Keyboard nav | .NET code in ToolStrip | Windows USER32.DLL | +| Accessibility | Incomplete IAccessible | Full native MSAA support | +| Focus events | Not fired automatically | Fired by Windows | +| Visual flexibility | High (owner-draw, etc.) | Limited (standard look) | +| Embedded controls | Supported | Not supported | +| Screen reader | Broken for keyboard | Works fully | + +MainMenu was deprecated in .NET 2.0 in favor of MenuStrip, but it remains +fully functional and has superior accessibility support because it delegates +to the Windows menu manager rather than reimplementing menu logic in .NET. + +5.2 Implementation Architecture +------------------------------- + +The implementation adds a parallel menu system that can be toggled: + +``` +MainForm + ├── MainformMenu (MenuStripEx) - Original, hidden when native menu active + └── _nativeMenu (MainMenu) - New, set as Form.Menu property + ├── File + ├── Emulation + ├── View + ├── Config + ├── Tools + ├── [System menus - hidden by default] + └── Help +``` + +Key design decisions: + +1. **Parallel Implementation:** Both menu systems exist; the native menu doesn't + replace the code, just provides an accessible alternative + +2. **Direct Method Calls:** Instead of trying to reuse ToolStrip event handlers + (which expect ToolStripMenuItem senders), native menu items call the + underlying methods directly + +3. **Lazy Initialization:** Native menu is created on first use + +4. **Toggle Support:** Methods exist to switch between menu systems if needed + +5.3 Menu Structure Mapping +-------------------------- + +The native menu replicates the ToolStrip menu structure: + +``` +Original (ToolStrip) Native (MainMenu) +───────────────────── ───────────────── +FileSubMenu → CreateFileMenu() + ├── OpenRomMenuItem → MenuItem("&Open ROM...") + ├── SaveStateSubMenu → MenuItem("&Save State") + │ ├── SaveState1MenuItem → MenuItem("1") + │ └── ... → ... + └── ... → ... +EmulationSubMenu → CreateEmulationMenu() +ViewSubMenu → CreateViewMenu() +ConfigSubMenu → CreateConfigMenu() +ToolsSubMenu → CreateToolsMenu() +NESSubMenu → CreateNesMenu() +[other system menus] → [Create*Menu() methods] +HelpSubMenu → CreateHelpMenu() +``` + +5.4 Event Handler Delegation +---------------------------- + +The native menu items cannot directly use the original event handlers because +those handlers often cast the sender to ToolStripMenuItem: + +```csharp +// Original handler - expects ToolStripMenuItem sender +private void QuickSavestateMenuItem_Click(object sender, EventArgs e) + => SaveQuickSaveAndShowError(int.Parse(((ToolStripMenuItem) sender).Text)); +``` + +Solution: Call the underlying methods directly with explicit parameters: + +```csharp +// Native menu - calls method directly +saveStateMenu.MenuItems.Add(new MenuItem("1", (s, e) => SaveQuickSaveAndShowError(1))); +saveStateMenu.MenuItems.Add(new MenuItem("2", (s, e) => SaveQuickSaveAndShowError(2))); +// etc. +``` + +For handlers that don't depend on sender properties, direct delegation works: + +```csharp +// These handlers don't inspect the sender, so direct delegation is fine +menu.MenuItems.Add(new MenuItem("&Pause", (s, e) => PauseMenuItem_Click(s, e))); +menu.MenuItems.Add(new MenuItem("&Open ROM...", (s, e) => OpenRomMenuItem_Click(s, e))); +``` + +5.5 System-Specific Menu Management +----------------------------------- + +BizHawk shows different menus based on the loaded emulator core (NES, SNES, etc.). +The native implementation handles this with: + +1. All system menus are created at initialization +2. All system menus are hidden by default via HideAllSystemMenus() +3. Menus should be shown/hidden based on the loaded core (requires integration) + +```csharp +private MenuItem _nativeNesMenu; +private MenuItem _nativeSnesMenu; +// etc. + +private void HideAllSystemMenus() +{ + _nativeNesMenu.Visible = false; + _nativeSnesMenu.Visible = false; + // etc. +} +``` + +================================================================================ +6. TECHNICAL IMPLEMENTATION DETAILS +================================================================================ + +6.1 File Locations and Structure +-------------------------------- + +**Main Form Native Menu:** + +New file: + src/BizHawk.Client.EmuHawk/MainForm.NativeMenu.cs + +This file is a partial class extension of MainForm containing: + - Native menu field declarations + - InitializeNativeMenu() - Main initialization method + - Create*Menu() methods - One per top-level menu + - HideAllSystemMenus() - Hides all system-specific menus + - UseToolStripMenu() / UseNativeMenu() - Toggle methods + +Modified file: + src/BizHawk.Client.EmuHawk/MainForm.cs + +Added call to InitializeNativeMenu() after InitializeComponent(): +```csharp +InitializeComponent(); +InitializeNativeMenu(); +``` + +**Lua Console Native Menu:** + +New file: + src/BizHawk.Client.EmuHawk/tools/Lua/LuaConsole.NativeMenu.cs + +This file is a partial class extension of LuaConsole containing: + - Native menu field declarations + - InitializeNativeMenu() - Main initialization method + - CreateFileMenu() - File menu (New/Open/Save Session, Recent) + - CreateScriptMenu() - Script menu (New/Open/Toggle/Edit/Remove scripts) + - CreateSettingsMenu() - Settings menu (options and text editor registration) + - CreateHelpMenu() - Help menu (Lua functions list, online docs) + - UseToolStripMenu() / UseNativeMenu() - Toggle methods + +Modified file: + src/BizHawk.Client.EmuHawk/tools/Lua/LuaConsole.cs + +Added call to InitializeNativeMenu() at end of constructor: +```csharp +// Initialize native Win32 menu for screen reader accessibility +InitializeNativeMenu(); +``` + +6.2 Initialization Flow +----------------------- + +``` +MainForm Constructor + │ + ├── InitializeComponent() + │ └── Creates ToolStrip menu (MainformMenu) + │ + └── InitializeNativeMenu() + │ + ├── Check _useNativeMenu flag + │ + ├── Create MainMenu instance + │ + ├── Create all menu structures + │ ├── CreateFileMenu() + │ ├── CreateEmulationMenu() + │ ├── CreateViewMenu() + │ ├── CreateConfigMenu() + │ ├── CreateToolsMenu() + │ ├── CreateNesMenu() + │ ├── ... (other system menus) + │ └── CreateHelpMenu() + │ + ├── Add all menus to MainMenu.MenuItems + │ + ├── HideAllSystemMenus() + │ + ├── Set Form.Menu = _nativeMenu + │ + └── Hide MainformMenu (ToolStrip) +``` + +6.3 Menu Toggling Mechanism +--------------------------- + +The implementation supports runtime switching between menu systems: + +```csharp +// Switch to ToolStrip menu +private void UseToolStripMenu() +{ + Menu = null; // Remove native menu + MainformMenu.Visible = true; // Show ToolStrip menu + _useNativeMenu = false; +} + +// Switch to native menu +private void UseNativeMenu() +{ + if (_nativeMenu == null) + InitializeNativeMenu(); + else + { + Menu = _nativeMenu; + MainformMenu.Visible = false; + } + _useNativeMenu = true; +} +``` + +This could be exposed as a user preference for accessibility. + +6.4 Handler Resolution Strategy +------------------------------- + +Three patterns are used for connecting menu items to actions: + +**Pattern 1: Direct handler delegation (when sender is not inspected)** +```csharp +new MenuItem("&Open ROM...", (s, e) => OpenRomMenuItem_Click(s, e)) +``` + +**Pattern 2: Direct method call with explicit parameter** +```csharp +new MenuItem("1", (s, e) => SaveQuickSaveAndShowError(1)) +new MenuItem("2", (s, e) => SaveQuickSaveAndShowError(2)) +``` + +**Pattern 3: Direct method call discarding result** +```csharp +new MenuItem("1", (s, e) => { _ = LoadQuickSave(1); }) +``` + +The appropriate pattern was determined by examining each original handler in +MainForm.Events.cs and MainForm.Designer.cs. + +================================================================================ +7. THE TOOLBAR ACCESSIBILITY PROBLEM +================================================================================ + +After implementing native menus, a second critical accessibility issue was +discovered: toolbar buttons (ToolStripButton controls) were also inaccessible +to screen readers during keyboard navigation. This section documents the +problem and the extensive attempts to resolve it. + +7.1 ToolStripButton Keyboard Accessibility Failure +--------------------------------------------------- + +BizHawk's tool windows (Lua Console, RAM Watch, Hex Editor, Cheats) use +ToolStrip controls containing ToolStripButton items for toolbar functionality. +The Lua Console toolbar, for example, contains buttons for: + + - New Script, Open Script, Toggle, Refresh, Pause + - Edit, Remove, Duplicate, Clear Console + - Move Up, Move Down + +Testing with NVDA revealed the same pattern as menus: + - **Mouse hover:** NVDA announces button names correctly + - **Keyboard Tab/Arrow:** NVDA remains completely silent + +This means a blind user could activate toolbar buttons with a mouse (with +screen reader mouse tracking), but could not use keyboard navigation at all. + +7.2 The Mouse vs Keyboard Discrepancy +------------------------------------- + +The technical explanation mirrors the menu problem: + +**Mouse Navigation (Works):** +1. User moves mouse over toolbar button +2. NVDA tracks cursor position via polling +3. NVDA calls AccessibleObjectFromPoint(x, y) +4. Windows returns IAccessible for the ToolStripButton +5. NVDA queries accName → "New Script" +6. NVDA announces "New Script, button" + +**Keyboard Navigation (Fails):** +1. User presses Tab to enter toolbar +2. ToolStrip receives focus (container level) +3. User presses Arrow keys to move between buttons +4. ToolStrip handles navigation internally +5. Visual focus rectangle moves to next button +6. **NO EVENT_OBJECT_FOCUS is fired** +7. NVDA has no notification that focus changed +8. NVDA remains silent + +The ToolStrip control manages an internal "selected item" state that is +completely disconnected from the Windows accessibility event system. + +7.3 Why AccessibleName Property Is Insufficient +----------------------------------------------- + +A common misconception is that setting AccessibleName on a control is +sufficient for screen reader compatibility. This is incorrect. + +```csharp +// This does NOT fix keyboard accessibility +toolStripButton1.AccessibleName = "New Script"; +toolStripButton1.AccessibleDescription = "Create a new Lua script"; +toolStripButton1.AccessibleRole = AccessibleRole.PushButton; +``` + +The AccessibleName property only affects what is RETURNED when a screen reader +QUERIES the control's IAccessible interface. It does not cause the screen +reader to query in the first place. + +Screen readers query IAccessible in response to: +1. Mouse position changes (hit testing) +2. WinEvents (EVENT_OBJECT_FOCUS, EVENT_OBJECT_SELECTION, etc.) +3. Explicit user commands ("read current focus") + +During keyboard navigation within a ToolStrip, none of these triggers occur: +- Mouse hasn't moved +- No WinEvents are fired by ToolStrip +- The "current focus" from Windows' perspective is still the ToolStrip + container, not the individual button + +Therefore, AccessibleName is necessary but not sufficient. Without proper +focus events, the screen reader never knows to read the AccessibleName. + +7.4 Attempted Solutions for Toolbar Buttons +------------------------------------------- + +Multiple approaches were attempted before finding a working solution. + +7.4.1 AccessibleName on ToolStripButton +--------------------------------------- + +First attempt: Add AccessibleName to all toolbar buttons in Designer.cs: + +```csharp +// In LuaConsole.Designer.cs +this.NewScriptToolbarItem.AccessibleName = "New Script"; +this.OpenScriptToolbarItem.AccessibleName = "Open Script"; +this.ToggleScriptToolbarItem.AccessibleName = "Toggle Script"; +// ... etc for all buttons +``` + +**Result:** Mouse reading worked, keyboard navigation remained silent. + +**Why it failed:** As explained above, AccessibleName only sets the value +returned by IAccessible.accName. Without focus events, NVDA never queries it. + +7.4.2 Standard WinForms Button Controls +--------------------------------------- + +Second attempt: Replace ToolStripButton with standard System.Windows.Forms.Button +controls, which are native Windows BUTTON class wrappers: + +```csharp +// Replace ToolStrip with Panel containing Buttons +var newButton = new Button +{ + Text = "New", + AccessibleName = "New Script", + Width = 60, + Height = 25, + TabStop = true +}; +newButton.Click += (s, e) => NewScriptMenuItem_Click(s, e); +toolbarPanel.Controls.Add(newButton); +``` + +**Result:** Mouse reading worked. Keyboard navigation STILL did not announce. + +**Why it failed:** This was unexpected. Standard Button controls are native +Windows controls with supposedly full accessibility support. Investigation +revealed the issue: + +The WinForms Button control wraps the native BUTTON class but focus handling +goes through the WinForms message loop. When Tab moves focus between buttons: + +1. WinForms receives WM_KEYDOWN for Tab +2. WinForms calls SelectNextControl() internally +3. The .NET Control.Focus() method is called +4. Eventually, Windows SetFocus() is called +5. **However**, the focus event that fires goes to the parent Form +6. Individual button focus events are not propagated correctly + +This is a WinForms architectural issue where the framework intercepts and +handles focus at the container level rather than letting Windows manage +individual control focus natively. + +Additionally, testing revealed that even when using GotFocus events to +manually fire NotifyWinEvent, NVDA still did not respond consistently. + +7.4.3 NotifyWinEvent for Focus Events +------------------------------------- + +Third attempt: Manually fire MSAA focus events when buttons receive focus: + +```csharp +private const uint EVENT_OBJECT_FOCUS = 0x8005; +private const int OBJID_CLIENT = unchecked((int)0xFFFFFFFC); + +[DllImport("user32.dll")] +private static extern void NotifyWinEvent(uint eventId, IntPtr hwnd, + int objectId, int childId); + +private void FireAccessibilityFocusEvent(Control control) +{ + if (control != null && control.IsHandleCreated) + { + NotifyWinEvent(EVENT_OBJECT_FOCUS, control.Handle, OBJID_CLIENT, 0); + } +} + +// Wire up to GotFocus event +button.GotFocus += (s, e) => FireAccessibilityFocusEvent((Control)s); +``` + +**Result:** Events fired (verified with AccEvent.exe) but NVDA still silent. + +**Why it failed:** Multiple issues compound: + +1. **Timing:** The event fires but NVDA's event hook may process it before + the control's IAccessible state is fully updated + +2. **Object ID Mismatch:** OBJID_CLIENT (-4) refers to the client area of + the window. NVDA queries AccessibleObjectFromEvent() which may not + correctly resolve to the button's IAccessible + +3. **WinForms IAccessible Implementation:** WinForms controls implement + IAccessible through System.Windows.Forms.AccessibleObject, which creates + a managed wrapper. The relationship between the HWND, object IDs, and + the managed AccessibleObject may not be what NVDA expects + +4. **Child ID Calculation:** For container controls with multiple accessible + children, the childId parameter must correctly identify which child. For + a simple Button, childId=0 should work, but WinForms may use different + conventions + +5. **NVDA Event Filtering:** NVDA has complex event filtering logic and may + ignore events that don't match expected patterns. The WinForms control + hierarchy doesn't match what NVDA expects from native controls. + +7.4.4 Why All Managed Control Solutions Failed +---------------------------------------------- + +The fundamental problem is architectural: WinForms controls are managed (.NET) +wrappers around native Windows concepts, but they don't faithfully replicate +native accessibility behavior. + +**Native Windows Controls:** +- BUTTON, LISTBOX, COMBOBOX, etc. are implemented in USER32.DLL and COMCTL32.DLL +- Focus changes fire WinEvents automatically at the OS level +- IAccessible is implemented by oleacc.dll proxies that understand the controls +- Screen readers have decades of compatibility testing with these controls + +**WinForms Controls:** +- Managed reimplementations with different internal architecture +- Focus management goes through .NET Control base class +- IAccessible is implemented by managed AccessibleObject class +- Accessibility events are optional and often missing +- Screen reader compatibility is inconsistent + +**ToolStrip Controls (Worst Case):** +- Entirely custom control suite introduced in .NET 2.0 +- All rendering and navigation is managed code +- ToolStripItem is not a Control - it's a Component without an HWND +- Accessibility was an afterthought, not a design requirement +- No direct correspondence to any native Windows control + +The only reliable solution is to use actual native Windows controls that have +built-in, tested, and reliable accessibility support. + +================================================================================ +8. THE LISTVIEW TOOLBAR SOLUTION +================================================================================ + +After all managed control approaches failed, the solution was found: replace +the ToolStrip toolbar with a ListView control configured to function as a +toolbar. ListView is a native Windows control (SysListView32) with full +accessibility support. + +8.1 Why ListView Works +---------------------- + +ListView is a Common Controls library control (comctl32.dll) that wraps the +native Windows SysListView32 class. Unlike ToolStrip: + +| Aspect | ToolStrip | ListView | +|-----------------------|------------------------------|------------------------------| +| Implementation | Managed .NET code | Native Windows control | +| HWND | Container only | Full native window | +| Item Implementation | ToolStripItem (Component) | LVITEM (native structure) | +| Focus Management | Internal .NET code | Windows USER32.DLL | +| Accessibility Events | Not fired | Automatic by Windows | +| IAccessible | Managed AccessibleObject | oleacc.dll native proxy | +| Screen Reader Support | Broken | Full native support | + +When keyboard focus moves between ListView items: +1. User presses Arrow key +2. Windows handles navigation in native code +3. Windows fires EVENT_OBJECT_FOCUS automatically +4. NVDA receives the event via SetWinEventHook +5. NVDA queries IAccessible for the focused item +6. NVDA announces the item text + +This all happens at the Windows OS level without any .NET code involvement +in the accessibility pathway. + +8.2 ListView as Toolbar Architecture +------------------------------------ + +The ListView is configured to emulate toolbar behavior: + +```csharp +_toolbarListView = new ListView +{ + Name = "ToolbarListView", + AccessibleName = "Script Toolbar", + AccessibleRole = AccessibleRole.ToolBar, // Announces as toolbar + View = View.List, // Horizontal list of items + SmallImageList = _toolbarImageList, // Icons for each button + Dock = DockStyle.Top, // Position like a toolbar + Height = 30, // Standard toolbar height + MultiSelect = false, // Single selection + TabIndex = 0, // First in tab order + TabStop = true, // Keyboard accessible + HideSelection = false, // Always show selection + Activation = ItemActivation.OneClick, // Click to activate + FullRowSelect = true // Select entire item +}; +``` + +Each toolbar "button" becomes a ListViewItem: + +```csharp +_toolbarListView.Items.Add(new ListViewItem("New Script", "New") { Tag = "New" }); +_toolbarListView.Items.Add(new ListViewItem("Open Script", "Open") { Tag = "Open" }); +_toolbarListView.Items.Add(new ListViewItem("Toggle", "Toggle") { Tag = "Toggle" }); +// ... etc +``` + +The Tag property stores an action identifier for the click handler. + +8.3 Implementation Details +-------------------------- + +**File Structure:** + +Each tool window has a NativeMenu.cs partial class file containing: +- ListView toolbar declaration +- ImageList for toolbar icons +- CreateAccessibleToolbar() method +- Event handlers for ListView interaction +- ExecuteToolbarAction() dispatch method + +**Lua Console Implementation:** + +File: src/BizHawk.Client.EmuHawk/tools/Lua/LuaConsole.NativeMenu.cs + +```csharp +public partial class LuaConsole +{ + private ListView _toolbarListView; + private ImageList _toolbarImageList; + + private void CreateAccessibleToolbar() + { + // Hide the original ToolStrip + toolStrip1.Visible = false; + + // Create ImageList for toolbar icons + _toolbarImageList = new ImageList(); + _toolbarImageList.ImageSize = new Size(20, 20); + _toolbarImageList.ColorDepth = ColorDepth.Depth32Bit; + _toolbarImageList.Images.Add("New", Resources.NewFile); + _toolbarImageList.Images.Add("Open", Resources.OpenFile); + // ... add all icons + + // Create ListView configured as toolbar + _toolbarListView = new ListView { /* ... configuration ... */ }; + + // Add toolbar items + _toolbarListView.Items.Add(new ListViewItem("New Script", "New") { Tag = "New" }); + // ... add all items + + // Wire up event handlers + _toolbarListView.ItemActivate += ToolbarListView_ItemActivate; + _toolbarListView.KeyDown += ToolbarListView_KeyDown; + + // Add to form and position + Controls.Add(_toolbarListView); + _toolbarListView.BringToFront(); + } +} +``` + +**RAM Watch Implementation:** + +File: src/BizHawk.Client.EmuHawk/tools/Watch/RamWatch.NativeMenu.cs + +Similar structure with buttons specific to RAM Watch: +- New List, Open, Save +- New Watch, Edit Watch, Remove Watch +- Duplicate, Split, Poke Address, Freeze Address +- Insert Separator, Move Up, Move Down + +8.4 Event Handling for ListView Toolbar +--------------------------------------- + +Two event handlers manage user interaction: + +**ItemActivate Handler (Mouse Click):** + +```csharp +private void ToolbarListView_ItemActivate(object sender, EventArgs e) +{ + if (_toolbarListView.SelectedItems.Count == 0) return; + var tag = _toolbarListView.SelectedItems[0].Tag?.ToString(); + ExecuteToolbarAction(tag); +} +``` + +**KeyDown Handler (Keyboard Activation):** + +```csharp +private void ToolbarListView_KeyDown(object sender, KeyEventArgs e) +{ + if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Space) + { + if (_toolbarListView.SelectedItems.Count > 0) + { + var tag = _toolbarListView.SelectedItems[0].Tag?.ToString(); + ExecuteToolbarAction(tag); + e.Handled = true; + } + } +} +``` + +**Action Dispatch:** + +```csharp +private void ExecuteToolbarAction(string action) +{ + switch (action) + { + case "New": NewScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Open": OpenScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Toggle": ToggleScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Refresh": RefreshScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Pause": PauseScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Edit": EditScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Remove": RemoveScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Copy": DuplicateScriptMenuItem_Click(this, EventArgs.Empty); break; + case "Clear": ClearConsoleMenuItem_Click(this, EventArgs.Empty); break; + case "Up": MoveUpMenuItem_Click(this, EventArgs.Empty); break; + case "Down": MoveDownMenuItem_Click(this, EventArgs.Empty); break; + } +} +``` + +The action dispatch reuses the existing menu item click handlers, ensuring +identical behavior between menu and toolbar activation. + +8.5 Performance Considerations +------------------------------ + +The ListView toolbar solution has a minor performance trade-off: + +**Advantages:** +- Full NVDA keyboard accessibility +- Native Windows control with hardware-accelerated rendering +- Consistent with Windows UI conventions +- No custom accessibility code required + +**Disadvantages:** +- ListView is a heavier control than ToolStrip +- Slightly more memory usage +- Marginally slower initial creation +- Visual style differs from ToolStrip (shows as a list, not buttons) + +In practice, the performance difference is negligible. The ListView toolbar +may feel "slightly slow" during rapid keyboard navigation compared to the +original ToolStrip, but this is because: + +1. NVDA intercepts and processes focus events +2. NVDA announces each item as focus moves +3. This adds ~50-100ms of speech/braille output time per item + +This is inherent to screen reader operation, not a deficiency in the +implementation. Sighted users navigating the same toolbar would not notice +any performance difference. + +================================================================================ +9.

KNOWN LIMITATIONS AND FUTURE WORK +================================================================================ + +Current limitations: + +1. **Dynamic Menu Population:** Some menus (Recent ROM, Recent Movie, External + Tools, Preferred Cores, Disk menus) are populated dynamically at runtime. + The native menu has placeholder items that would need additional integration + to populate dynamically. + +2. **System Menu Visibility:** The system-specific menus (NES, SNES, etc.) are + created but hidden. Integration is needed to show/hide them based on the + loaded core, mirroring the ToolStrip menu behavior. + +3. **Checkmarks and State:** Some menu items have checkmarks indicating state + (e.g., "Read-only" mode, "Display FPS"). The native menu doesn't currently + sync these states - would need integration with the existing state update + methods. + +4. **Shortcut Key Display:** The ToolStrip menu displays keyboard shortcuts + next to items. The native Menu can display shortcuts but this would need + to be synchronized with the hotkey configuration. + +5. **Menu Images:** The ToolStrip menu has icons on some items. MainMenu + supports icons via owner-draw but this is not implemented. + +6. **No User Toggle:** Currently the native menu is always used when + _useNativeMenu = true. A user-accessible preference could be added. + +7. **ListView Toolbar Visual Style:** The ListView toolbar appears as a list + of items rather than traditional toolbar buttons. This is a visual trade-off + for accessibility. Future work could explore owner-draw to create a more + traditional toolbar appearance while retaining accessibility. + +8. **Cheats Window:** The Cheats tool has accessible names added to controls + but does not yet have a native menu or ListView toolbar implementation. + +9. **Other Tool Windows:** Additional tool windows (RAM Search, Debugger, etc.) + have not been updated with accessibility features. + +Future work: + +1. Add configuration option to toggle between menu systems +2. Implement dynamic menu population for Recent items, External Tools, etc. +3. Add system menu visibility management tied to core loading +4. Sync checkmark states with application state +5. Display keyboard shortcuts from hotkey configuration +6. Consider hybrid approach: native menu for accessibility, keep ToolStrip + for users who prefer it +7. Extend ListView toolbar solution to remaining tool windows +8. Create owner-drawn ListView items that look like toolbar buttons +9. Document accessibility testing procedures for future contributors +10.
