[Closed] Display child window

It doesn’t appear that creating a pyside Application and then displaying a child window of that application is possible in 3ds Max. From what I’ve tested when you display the child window, there is no proper method of displaying it where it acts like a modal dialog and displaying on-top of the others. Does anyone know of a solution to this?

Attached is a simple example. Just drop the run.ms into max and it will execute the file. Then you click the popup button and then click in 3ds max you’ll see the window disappear behind max. It shouldn’t do this.
