Proper way of creating non-modal Qt window

[faulknermano]

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.

Actually, not just non-modal Qt widgets, but I also can't properly use QDialogs either. QPushButton presses crash XS.

Take this simple QDialog:

class Temp(QtWidgets.QDialog):
    def __init__(self, parent=None):
        super(Temp, self).__init__(parent)
        self.layout = QtWidgets.QGridLayout()
        self.setLayout(self.layout)
        self.button_load = QtWidgets.QPushButton('Load')
        self.button_load.clicked.connect(self.on_click_button_load)
        self.layout.addWidget(self.button_load, 0, 0, 1, 1)
    def on_click_button_load(self):
        print('hi')

Called simply:

from my_guis import Temp
w = Temp();
w.exec_()

It will bring up the dialog with a push button. Press the button once/twice and XS goes down. My console looks like:

Is this is an XS issue?
