以下是右边框示例
MouseArea {
id: mouseArea
acceptedButtons: Qt.LeftButton //只处理鼠标左键
property point clickPos: "0,0"
cursorShape: Qt.SizeHorCursor
anchors.top:parent.top
anchors.right:parent.right
anchors.topMargin: 30
width: 10
height: parent.height
anchors.rightMargin: 0
//hoverEnabled: true
onPressed: { //接收鼠标按下事件
clickPos = Qt.point(mouse.x,mouse.y)
}
onPositionChanged: { //鼠标按下后改变位置
//鼠标偏移量
var delta = Qt.point(mouse.x-clickPos1.x, mouse.y-clickPos1.y)
//如果mainwindow继承自QWidget,用setPos
mainWindow.width = mainWindow.width + mouse.x-clickPos1.x
}
}
用以上代码进行拉伸的时候窗口会出现闪烁现象，经过一番仔细的搜索，在cpp文件中加入下面代码就可以解决
QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL);
