Display a OpenGL QWindow in QML

john_god

Hello good people

I have a QML main file

@Rectangle {
id: root
width: 640
height: 480
color: "#fff396"

property int margin: 10
MenuHybrid{ // this is just a QML menu with QML buttons
    id: menu
    anchors.top: parent.top
    anchors.left: parent.left
    anchors.margins: margin
}

//How to display a QWindow class with Opengl in replace of this black rectangle ???
Rectangle {
id: drawingBoard
color: "black"

    anchors.left: parent.left
    anchors.bottom: parent.bottom
    anchors.right: parent.right
    anchors.top: menu.bottom
    anchors.margins: margin
}

}

I have added to the project a c++ QWindow class, I don't know how to display it in QML.
I've read the docs about the QML and C++ integration, but still haven't figure out weel the logic.
Basically I want to achieve a fancy QML paint application, with a menu with buttons and QGLWidget area, so the user draws stuff with mouse clicks. Since QGLWidgets is not recommended for QML app, I believe, I'm thinking of a QWindow class.
Thanks

QGL* stuff is pretty much deprecated, consider moving to QOpenGL* classes instead.

And: every QML Item is an OpenGL painter, so you can also think about subclassing QQuickItem (OpenGL, you need to push the result into a texture to have it drawn) or QQuickPaintedItem (uses QPainter!).

I'm far from being an expert here, though. Would be nice if others joined in.
