[Maya-Python] capturing mouse clicks?

[Ravi Jagannadhan]

Hi all, I'm trying to detect when a mouse button is clicked anywhere in
Maya as part of an event filter. I currently have this as an event filter:

from PySide2 import QtCore, QtWidgets
from shiboken2 import wrapInstance
from maya import OpenMayaUI

win_ptr = OpenMayaUI.MQtUtil.mainWindow()
win = wrapInstance(long(win_ptr), QtWidgets.QMainWindow)

class MyEventFilter(QtCore.QObject):

def eventFilter(self, watched, event):
print event.type(), watched, event


filter = MyEventFilter()
win.installEventFilter(filter)

But it doesn't seem to trap a mouse button press/release event (or at least
I don't see it in the output). What am I missing from this in order to
trap the mouse button events?

Thank you for your time,
Ravi

This is only going to catch events that aren't handled by child widgets and
bubble up to the window. If you want to catch every mouse click in the
whole app, you would have to install it on the QApplication. Note this will
slow Maya down because of a python function being called for every event in
the system.

Thank you for the response. The issue I'm looking into happens also when
clicking menu items in the top level window, so maybe I'll start there.
Thanks again.
