feat: add xdg-activation-v1 protocol support for window activation

18202781743 · 18202781743 · commit 5eb836228dc2 · 2026-06-01T18:10:02.000+08:00
tokens

Implement integration with the xdg-activation-v1 Wayland protocol
to support requesting activation tokens, both synchronously (with
a 2-second timeout) and asynchronously. This enables proper window
activation and focus-stealing prevention on Wayland compositors.

Key components:
- XdgActivation class: singleton providing requestToken() and
requestTokenAsync() methods
- XdgActivationPrivate: extends QWaylandClientExtensionTemplate to bind
the protocol
- XdgActivationTokenV1: wrapper for xdg_activation_token_v1 with done
signal
- Uses last input device serial and seat for proper activation context
- Checks for Wayland platform before attempting activation
- Integrates into dde-shell-frame build system with protocol XML
generation

Log: Added xdg-activation-v1 protocol implementation for window
activation tokens

Influence:
1. Test requestToken() on X11 platforms (should return empty without
error)
2. Test requestToken() on Wayland with valid window handle
3. Test requestToken() timeout behavior with unconsumed token
4. Test requestTokenAsync() callback execution
5. Verify token retrieval under compositors supporting xdg-activation-v1
6. Verify no crashes or hangs when protocol is not available

feat: 添加 xdg-activation-v1 协议支持，用于窗口激活令牌

实现 xdg-activation-v1 Wayland 协议集成，支持同步（带2秒超时）和异步方
式请求激活令牌。这使得在 Wayland 合成器上能够正确进行窗口激活和防止焦点
窃取。

关键组件：
- XdgActivation 类：单例，提供 requestToken() 和 requestTokenAsync()
方法
- XdgActivationPrivate：继承 QWaylandClientExtensionTemplate 以绑定协议
- XdgActivationTokenV1：xdg_activation_token_v1 的包装类，包含 done 信号
- 使用最后输入设备序列和 seat 提供正确的激活上下文
- 在尝试激活前检查是否为 Wayland 平台
- 集成到 dde-shell-frame 构建系统并生成协议 XML

Log: 新增 xdg-activation-v1 协议实现，用于窗口激活令牌

Influence:
1. 在 X11 平台上测试 requestToken()（应返回空值且无错误）
2. 在 Wayland 上使用有效窗口句柄测试 requestToken()
3. 测试 requestToken() 在令牌未被消耗时的超时行为
4. 测试 requestTokenAsync() 回调函数正常执行
5. 验证在支持 xdg-activation-v1 的合成器上能够获取令牌
6. 验证协议不可用时无崩溃或挂起
