Proper way of creating non-modal Qt window

Hi! I can create a modal Qt window via `window.exec_()` but when I try using `show()`, the frame comes up, but the window does not draw.

We have had similar issues with other applications and developed workarounds by hooking up with the host application's tick callback to call `processEvents()` and so to allow redraws and other events to tick.

But I was wondering what is the best approach with non-modal guis in xstudio?

Thank you for reading.

Start by reproducing the reported difference between Qt window.exec_() and show() in xSTUDIO, and trace how the host application's event loop handles the window. Compare the proposed tick-callback/processEvents() workaround with the intended non-modal GUI integration; done requires a documented, agreed approach that allows the window to draw and process events.
