关键摘要:

• 在TitleBar的QML文件中，使用了title.width > GStatus.needHideSideBarWidth来判断左侧间距的大小，这可能是一个逻辑错误，因为title.width可能小于GStatus.needHideSideBarWidth。
• 在ThumbnailListViewTools.js文件中，调用thumbnailModel.clearSelection()时没有检查thumnailListType是否等于Album.Types.ThumbnailTrash，这可能会导致在删除时没有正确清除选择。
• 在HaveImportedView.qml文件中，将visible属性设置为false可能会影响用户界面，需要确认这是否是预期的行为。

是否建议立即修改:
是

• 需要立即修正逻辑错误，以避免潜在的界面问题。
• 需要检查ThumbnailListViewTools.js中的删除逻辑，确保删除操作正确执行。
• 需要确认HaveImportedView.qml中隐藏视图的决策是否符合产品需求。
