Wow!
i've get this works !
instead of using QtGui.QApplication.activeWindow()
i've put QtGui.QApplication.desktop()
and it seems that the new Window is seen as a separated window
by the Os and Nuke, and there is no more crash when exiting nuke!
hope you can confirm this workaround ;)
import PySide.QtCore as QtCore
import PySide.QtGui as QtGui
class TestMainWindow(QtGui.QDialog):
def __init__(self,parent=QtGui.QApplication.desktop()):
super(TestMainWindow, self).__init__(parent)
self.hbox=QtGui.QHBoxLayout()
self.button=QtGui.QPushButton("TEST")
self.hbox.addWidget(self.button)
self.setLayout(self.hbox)
self.setWindowTitle("TestMainWindow")
wnd=TestMainWindow()
wnd.show()
