Docking in QtQuick [closed]

Question

As far as I understand there is no built-in functionality for dockable containers in QtQuick. I found a few sources where this is added, however I am having trouble deciding which way to go.

How to get a QMainWindow from ApplicationWindow QML file to allow use of QDockWidget with QML files

Can someone recommend a way (or preferably a library) to add docking to QtQuick?

Answer 1

I found a solution that works with multiple windows moving a widget from the main window (docked state) to a new window (undocked state).

Hoping that this is useful to others here is a complete example:

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.0
import QtQuick.Window 2.2

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Window {
        width: 100;
        height: 100;
        visible: false;
        id: wnd

        Rectangle {
            id: greenRect
            anchors.fill: parent
        }

        onClosing: {
            blueRect.state = "docked"
        }

    }

    Item {
        width: 200; height: 100

        Rectangle {
            id: redRect
            anchors.fill: parent
        }

        Rectangle {
            id: blueRect
            width: 50; height: 50
            x: 10; y: 10;
            color: "blue"

            states: [
                State {
                    name: "undocked"
                    ParentChange { target: blueRect; parent: greenRect; x: 10; y: 10 }
                },
                State {
                    name: "docked"
                    ParentChange { target: blueRect; parent: redRect; x: 10; y: 10 }
                }
            ]

            MouseArea {
                anchors.fill: parent;
                onClicked: {
                    blueRect.state = "undocked"
                    wnd.visible = true
                }
            }
        }
    }
}
