Just wondering if it is possible via Python to intercept Poser menu commands: Say I have a script that does something that Poser fails to do correctly, so on the menu choice I want to stop Poser doing its evil thing and execute my script instead.     

I'm unsure if this is possible. Would it not be quicker (not to mention easier); to just run your own script in the first place?

Running the script directly is an option, but when I put it under the main menu it saves me forgetting I have to use the script. 

That's why I asked whether it were possible at all. Next question would have been how difficult it is.

Direct lead was that the standard pose swap left-right does not work for Nova, but my script does. 

Yes, I thought that was for the purpose :)

Theoretically it is possible. Because the Poser UI is just wxPython. But then it depends on how the programmers have built the interface together. If they followed the rules, it should be possible to intercept the menu event.

How much effort is that? Depends on how well you know wxPython. In any case you have to find the window that is responsible for the event processing of the menu. Once you have found it, you can redirect the handler to your own script.

Thanks. I will leave it for now. I found more issues with that figure. I suspect they are mostly connected to actor's internal names not being to the Poserverse social convention of having first character of body part names always lower case; so Poser looking for 'hip' and not for 'Hip'.

With the 'mass' around this figure still being small and forecast of updates being dim, it may be easier for me just to make my own version and bulk rename everything.

Sadly there is no poser naming convention. But you can can use actor.Name().casfold() to ignore the case.

Yes I can tell Python but I cannot tell Poser ;--(

Apparently there is a de-facto naming convention, or Poser would have worked correctly.  It is just not published.
