QML烂笔头记忆

window：

无标题 FramelessWindowHint
暂记后续补充 WindowFlags

无边框窗口移动

MouseArea {

               anchors.fill: parent
               property point clickPos: "0,0"
               onPressed: {
                   clickPos = Qt.point(mouse.x,mouse.y)
                   }
               onPositionChanged: {
               //鼠标偏移量
               var delta = Qt.point(mouse.x-clickPos.x, mouse.y-clickPos.y)
               //如果mainwindow继承自QWidget,用setPos
               mainwindow.setX(mainwindow.x+delta.x)
               mainwindow.setY(mainwindow.y+delta.y)
               }
           }
