Hide Minimize, Maximize, And Close Button

[RajStartsHere]

Can There Be A Mod To Hide Minimize, Maximize, And Close Button From The Title Bar

Personally, I Use AltSnap To Do All The Things Except Close Which Is By Either By Triggering AltF4 Or Clicking Middle-Mouse Button Over The Taskbar Icon

It Would Be Lovely

[RajStartsHere]

Any Hope...

[takattowo]

Well, doable and not doable, because not all app use win32 shell, many app paints its own, needs per-app hook. So no clean universal mod.

I'm Still Interested

[takattowo]

Alright, I will make one for you, targeting win32 shell windows only. Will take a while.

There you go, but I made this quickly, so expect bugs. @m417z do you think this should consider to be a mod in Windhawk's collections?

Sure, why not. Perhaps it can be an addition to an existing mod, such as Hide Titlebar Icon and Text. @darkthemer what do you think?

[darkthemer]

I wouldn't mind if @takattowo is fine with it too.

However, I have some concerns. Removing the titlebar buttons this way has some unwanted side effects, such as:

1. Being unable to maximize and minimize the window (through dragging window to top, double-clicking titlebar, pressing win + up/down)
2. Disabling the titlebar context menu
3. Hiding the titlebar icon as well
4. Messing with other mods somehow? (try with translucent-windows, the titlebars and borders don't get colored accordingly)

Unfortunately, I have no idea on how to resolve these yet.

[takattowo]

Well, thats exactly what the guy wanted LOL.

I can add an option to pick which buttons to hide. And yeah, your concerns are valid: stripping WS_ also kills the matching shortcuts. Seems like I need to paint the title bar to hide the buttons.
