hi, list! I have to ask for help because I can't create an sub window on
Window {...}.
I've tried some days, after Google still can't solved my problem.

main.qml

import QtQuick 2.2
import QtQuick.Window 2.1
Window {
id: mainWindow
visible: true
width: 760; height: 520
color: "red"
property variant win; // you can hold this as a reference..
Text {
text: "Click here to open sub window 2!"
anchors.centerIn: parent
}
Window {
id: subWindow_1
width: 555
height: 333
visible: true
flags: Qt.SubWindow
}
MouseArea {
anchors.fill: parent
onClicked: {
var component = Qt.createComponent("subwindow2.qml");
win = component.createObject(mainWindow);
win.show();
}
}
}

subwindow2.qml

import QtQuick 2.2
import QtQuick.Window 2.1
Window {
id: subWindow_2
visible: true
width: 500; height: 300
color: "blue"
flags: Qt.SubWindow
Rectangle {
anchors.fill: parent
color: "lightGrey"
Text {
anchors.centerIn: parent
text: "Sub Window 2"
}
}
}

See the code, it's can open two window, But can't open as sub window in
parent.
Any help / tips are very welcome!
Thanks you!

What do you mean by sub window? If you mean you are trying to create an MDI interface, with a window acting as a desktop and having more windows inside, that's not supported in Qt Quick and is unlikely at this point, since the widgets implementation turned out to be quite bug-prone, and MDI has anyway mostly fallen out of fashion. When you declare a Window inside a Window, it becomes "transient for" the outer window: a hint is given to the window manager that they are related to each other, so usually it will be shown centered over its transient parent.

Actually, I don't really want an MDI interface. I just want load or open
another qml as child Window show inside the parent.
like this (using QML's Rectangle):
Loading Image...

not like this (using QML's Window):
Loading Image...

So just use Rectangle :) or Item if you just want an empty item, or
Component to load some QML from file.

The best way is to use a Loader item.

Yes Yuchen. But you should anchor the Loader like any other item.
