Subject: [PATCH] fix: fix touchscreen double-tap and long-press handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Fixed touchscreen double-tap not maximizing/restoring windows by
adding a separate TapHandler for non-mouse devices
2. Fixed touchscreen long-press not showing system window menu by
handling it in the non-mouse TapHandler
3. Added device filtering to prevent conflicts between mouse and
touchscreen events
4. The original TapHandler now only accepts mouse events with
acceptedDevices: PointerDevice.Mouse
5. The new TapHandler accepts all non-mouse devices (touchscreen,
stylus, etc.) and handles their gestures

Log: Fixed touchscreen double-tap to maximize/restore windows and long-
press to show system menu

Influence:
1. Test double-tap on touchscreen to maximize and restore windows
2. Test long-press on touchscreen to show system window menu
3. Verify mouse right-click and left-click double-tap still work
correctly
4. Test with different input devices (touchscreen, mouse, stylus) to
ensure proper device filtering
5. Verify no conflicts between mouse and touchscreen event handling

fix: 修复触摸屏双击和长按处理问题

1. 通过为非鼠标设备添加单独的TapHandler修复触摸屏双击无法最大化/还原窗口
的问题
2. 通过在非鼠标TapHandler中处理长按修复触摸屏长按无法显示系统窗口菜单的
问题
3. 添加设备过滤以防止鼠标和触摸屏事件冲突
4. 原TapHandler现在只接受鼠标事件（acceptedDevices:
PointerDevice.Mouse）
5. 新的TapHandler接受所有非鼠标设备（触摸屏、手写笔等）并处理其手势

Log: 修复触摸屏双击最大化/还原窗口和长按显示系统菜单功能

Influence:
1. 测试触摸屏双击以最大化和还原窗口
2. 测试触摸屏长按以显示系统窗口菜单
3. 验证鼠标右键和左键双击功能是否正常工作
4. 测试不同输入设备（触摸屏、鼠标、手写笔）以确保正确的设备过滤
5. 验证鼠标和触摸屏事件处理之间没有冲突
