How to create a framelesswindow and can resize the window's size?

[hezf]

I use this to create a frameless window,but this window can't resize

ApplicationWindow {
flags:  Qt.Window|Qt.FramelessWindowHint

I want to resize the window like a Qt::SizeAllCursor at right bottom~

Hi @hezf,
AFAIK we dont have something like QSizeGrip in QML yet. So I thought of giving a try to create our own QML based grip. Following is what seems to work. Ofcourse it needs lots of improvisation IMO :)
On the right-bottom corner is a small rectangle on which you can press and drag it. It is added just for visualization.

import QtQuick 2.5
import QtQuick.Window 2.0

Window {
    id: win
    width: 300
    height: 300
    visible: true
    flags: Qt.FramelessWindowHint

    Item {
        id: root //Dummy item as mapToItem requires Item
        anchors.fill: parent

        Rectangle {
            width: 10
            height: 10
            anchors.right: parent.right
            anchors.bottom: parent.bottom
            color: "red"

            MouseArea {
                anchors.fill: parent
                onPositionChanged: {
                    win.width += mapToItem(root,mouseX,mouseY).x-root.width
                    win.height += mapToItem(root,mouseX,mouseY).y-root.height
                }
            }
        }
    }
}

Can you try if it works for you ?
If some one has better ideas to improve it please share.
