objectarx and qt

[inno]

I saw many examples on github or code project.
However, there are no example files that are implemented as modal or modeless.
I tried to implement it, but it doesn't work.

Can you tell me the example file or method?

modeless dialog
If the dialog is active, you cannot click on the cad screen.

modal dialog box
I want the dialog to turn off and turn on again when I click the button and run cad-related.
