调用：

        MyIconButton {
             x: mainWindow.width-40
             y: -8
             width: 20
             height: 20
             radius: 5
             id: btClose
             Image {
                 id: name
                 width: 20
                 height:20
                 source:  "qrc:/image/close.png"
             }
             btn_txt: ""
             onClickedLeft: close()
