实现的效果为通过黑色矩形框预操作鼠标释放时更新窗口。效果图如下 1.功能
1.1 已实现功能
8个方向的缩放标题栏拖动标题栏双击最大化/正常窗口窗口最小尺寸预操作框颜色与背景色互补多屏幕默认标题栏
1.2 待开发功能
拖动到屏幕四周进行半屏全屏。
1.3 存在的问题
1.QWebEngineView
从测试效果来看对于普通widget效果较好但是如果是嵌入了QWebEngineView且其位于窗口四周就会出现问题。
其主要原因在于当事件进入QWebEngineView后会被其child(QtWebEngineCore::RenderWidgetHostViewQtDelegateWidget)吃掉导致后续事件不再进入主窗口从而无法触发我们的代码。这时我们还可以遍历QWebEngineView的children将事件安装到主窗口 auto childs view-children();for(auto child:childs){child-installEventFilter(this);}
但是这样显得太笨重了。而且即使如此鼠标样式的修改也会被QWebEngineView刷掉。因此对于QWebEngineView下是存在一些问题的。
2.多屏幕拖动时从低缩放比拖到高缩放比释放时会闪烁一次目前没有进一步分析原因。
2.探索的过程
2.1 关于无边框缩放的实现方式
目前网上无非两种方式
a)通过nativeEvent()实现。c - Qt/Windows, resizable frameless window - Stack Overflow
b)通过窗口的eventFilter()直接实现。
但是问题是前者基于windows接口不跨平台而后者则会出现抖动。
本文则是基于第二种方式并参考windows窗口的拖动方式通过预操作框避免抖动的问题。
2.2 实现思路
首先关于无边框窗口通过Qt标志处理
setWindowFlags(Qt::FramelessWindowHint);
然后关于缩放和拖动与网上大多数实现一致通过九宫格法实现 当鼠标位于不同区域时触发不同的操作。
而对于预处理框则是通过一个覆盖整个屏幕的透明窗口并重写paintEvent在其中绘制一个rect。
2.3 实现难点
1.首先是九宫格的思路了解了思路之后实现就比较简单了
2.对于预处理框首先是需要以全屏幕作为geometry否则会导致拖不到非主屏幕或者位置错误灯问题
3.其次是预处理框要实现window类似的与背景色互补(而非纯色)需要获取全屏幕图片作为背景绘制到预操作框然后再通过QPainter::RasterOp_SourceAndNotDestination模式取反。
4.最后就是对于多屏幕的位置缩放比灯。
二、代码
目录结构如下 其中
cursorTransform是用于鼠标位置和方向的计算framelessData则是一些全局变量framelessHelper则是对外的接口titleBar表示默认标题栏transparentRect则是实现预操作框
