How to obtain winId of qml Window?

[tubbadu]

Hello there! I'm writing a dock application touchscreen-oriented in Qml, but the only way I could find of setting it as a dock (so that it's made unmovable, unresizeable, frameless, always on top, not affected by showDesktop and MinimizeAllWindows, etc.. is to set in main.cpp this attribute:

KWindowSystem::setType(window.winId(), NET::Dock);

I used a QQuickWidget to display the qml code, and set that QQuickWidget to dock
now I need to create another window, child of the main "dock" window, and this window should too be marked as dock. How can I do? can I get the winId of that window from c++, so that I can set it using setType too?

I know it's a bit confusing but I'm confused too, it's the first time I'm doing something not 100% Qml... thanks in advance!

@fcarney but I have instanciated the Window object from the Qml... how can I call that method referring to that specific window?

You should provide code as to how and when you are creating this window that you need the id from.
QML Window is C++ type QQuickWindow which is of type QWindow.
