3dsmax python : delete pyqt instance

Coding
1

Hi

I have a pyqt script displaying a widget with some buttons doing some stuffs.

I start it like this, which is the recommended way :


class Dialog(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Dialog, self).__init__(parent)

if __name__ == '__main__':
    app = QtGui.QApplication.instance()

    if not app:
        print "new QApplication created"
        app = QtGui.QApplication([])

    window = Dialog()

the problem is that when hitting upper right cross button to exit the widget (closeEvent), it seems a lot of stuff stay in max memory.
for example if I do a qttimer which print some stuff every x seconds, once I close my window script, the timer still print stuff !!!

So, is there a way to totally exit, and if possible, deleting my Qapplication instance, so nothing stay in max memory, and next time I launch it it will create a new instance ?

Is there such problems with pyqt inside maya ?

There are various ways this could be done, simple way is to use make it a singleton. The deleteLater method is something you look for btw.
