Is there a way to trap the moment when a user change the current room (example: Pose to Material)
Is there a way to trap the moment when the current Poser document is being closed.

It would be great if I was able to bind a function to such events.
Thanks in advance.

Posers UI is wxPython. So: https://docs.wxpython.org/wx.aui.AuiManagerEvent.html

Were you finally able to figure out how to successfully intercept the events?

No.

Not sure if I understood correctly the online explanations but I suppose that the File->Close menu option is already intercepted and handled, as events aren't "going" further than the right destination window/panel.

When I see that the hierarchy window closes when a choose to close the current document, I was supposing that a kind of "Please close" event was being fired.

Then, I tried to add my panel to wx.aui.AuiManager. Upon closing the document, my dialog box is closed as well. But when I create a new document, my dialog is automatically re-opened, at the wrong place, either docked and undocked. 😂
I'm clearly missing something, lol

Solution found 😊  not using events but rather a simple poseraddon, with something like this in the __init__.,py

class MyClass(poseraddon.Addon, poseraddon.SceneObserver, poseraddon.SceneDataSaver, poseraddon.PrefsSaver):
    def __init__(self):
        self.addonInfo = {
            'id': 'com..my.addon',
            'author': 'me',
            'copyright': '(c) 2022 me',
            'name': "My addon",
            'version': '1.0',
            'observer': 1,
            'scenedata': 1,
        }

    def load(self):
        # load your stuff

    def unload(self):
        # unload your stuff

    def sceneDeleting(self, scene):
        # unload your stuff

    def sceneCreated(self, scene):
        # load your stuff
