Reviewer's GuideRefactors notification center margin handling to use dynamic, screen-aware dock geometry with device-pixel–aware calculations and stored margin properties, fixing positioning issues and flicker when the dock is shown/hidden or moved.

Hey there - I've reviewed your changes - here's some feedback:
- The
updateMarginsfunction repeats the pattern of resetting all margin values to 0 in several early-return branches; consider extracting this into a small helper (e.g.resetMargins()) to reduce duplication and make the intent clearer. - The
switch (dockPosition)uses raw numeric values (0/1/2) with comments forDOCK_TOP/RIGHT/BOTTOM; if the dock API exposes an enum or constants for these positions, using them instead of magic numbers would make the code more self-documenting and less error-prone. - For the bottom dock you explicitly gate the margin on
hideState === Dock.Hide, but for top and right positions the hide state is not considered (only geometry); it may be worth clarifying or aligning this behavior so that margin handling for hidden/auto-hidden docks is consistent across all positions.

Pull request overview
This PR improves the notification center's margin calculation to properly account for the dock's position and visibility. The change replaces a simple position-based margin calculation with a comprehensive geometry-based approach that handles device pixel ratios and dynamic dock state changes.
Key changes:
- Replaced
windowMargin(position)function withupdateMargins(frontendRect)that uses dock geometry instead of simple position checks - Added property storage for margin values (topMarginValue, rightMarginValue, bottomMarginValue) to avoid recalculation on every access
- Implemented device pixel ratio conversion to translate dock geometry from device pixels to logical pixels for accurate positioning

1. Fixed notification center window positioning logic to use frontendWindowRect for accurate dock geometry 2. Added special handling for bottom dock to avoid jitter by checking hideState 3. Improved margin calculation by considering actual visible dock area on screen edges 4. Added property binding for frontendRect updates when dock geometry changes Log: Fixed notification center positioning issues near dock edges Influence: 1. Test notification center positioning when dock is at top/right/bottom positions 2. Verify no jitter when dock is at bottom with hide/show states 3. Test positioning accuracy when dock spans multiple screens 4. Verify correct margin calculation when dock is partially off-screen 5. Test notification center behavior during dock position changes 6. Verify frontendRect updates properly when dock geometry changes fix: 修复通知中心窗口定位问题 1. 修复通知中心窗口定位逻辑，使用 frontendWindowRect 获取准确的 dock 几 何信息 2. 为底部 dock 添加特殊处理，通过检查 hideState 避免抖动问题 3. 改进边距计算，考虑屏幕边缘 dock 的实际可见区域 4. 添加 frontendRect 属性绑定，在 dock 几何信息变化时更新 Log: 修复通知中心在 dock 边缘的定位问题 Influence: 1. 测试通知中心在 dock 位于顶部/右侧/底部时的定位 2. 验证 dock 在底部隐藏/显示状态时无抖动 3. 测试 dock 跨多个屏幕时的定位准确性 4. 验证 dock 部分超出屏幕时的边距计算正确性 5. 测试 dock 位置变化时通知中心的行为 6. 验证 dock 几何信息变化时 frontendRect 正确更新 PMS: BUG-340795

deepin pr auto review这段代码主要对 Dock 面板（DockPanel）的窗口矩形计算逻辑进行了重构，并修改了通知中心（Notification Center）中关于 Dock 边距的计算逻辑。 以下是针对语法逻辑、代码质量、代码性能和代码安全的详细审查意见： 1. 语法逻辑
2. 代码质量
3. 代码性能
4. 代码安全
改进建议
总结：这次重构通过缓存计算结果提升了 C++ 端的性能，但引入了状态管理的复杂性（需要确保缓存始终有效）。QML 端的计算逻辑更加精细，但需注意边界情况和性能开销。最重要的是补全成员变量的初始化并修正 QML 中底部 Dock 的计算逻辑。 |
