[Sidefx-houdini-list] Intercepting menu buttons on Type Properties.

So I had a quick play with it. I tried installing an event filter to find when the dialog was closed, but that didn’t work. I suspect it’s possibly a threading issue.
What I’ve done below seems to work, but it’s a bit of a hack to be honest. As far as I can see though, there’s nothing that directly supports what you want.
To try it out, just copy the code below into Houdini's Python Source Editor, select a node and run “hou.session.test()” from the Python shell.
from time import sleep
from PySide import QtGui,QtCore
def launch_type_properties(current_node, on_close_callback):
#We want to make sure we don't use any existing window that has focus
existing_window = QtGui.QApplication.activeWindow()
#Open up the Type Properties window
active_window = None
found = False
#We don't want to loop forever in case something unexpected happens
active_window = QtGui.QApplication.activeWindow()
title = active_window.windowTitle()
#Error checking here sucks. Need to test edge cases where
# another dialog or window unexpectedly pops up
if title == "Edit Operator Type Properties" and existing_window!=active_window:
found = True
if active_window.isVisible() is False:
def on_close(window, current_node):
hou.ui.displayMessage("Type Properties Closed for "+current_node.name())
#Your menu should be able to pass the current node, rather than using selection like this
sel = hou.selectedNodes()
hou.ui.displayMessage("Make sure you select a node first")
current_node = sel

However, there maybe a (platform dependent) way of using Python to get a handle for the Type Properties window so you can figure out when it’s closed. In theory, it’s all PyQt now, so it’s possible that it might be relatively easy to do.
