[gme-users] Plug-in in background

[Gabriele Trombetti]

Hi all,
I need to make a plugin which starts when the user clicks on the icon, 
and then remains in background.

I will probably need another thread because some of its operations can 
block for a few seconds.
But apart from that, I tried just now with a dummy example which does 
not spawn another thread.

In the plugin I put a (never-ending) windows message loop (GetMessage, 
TranslateMessage, DispatchMessage) so that the GME interface is still 
responsive. BUT as soon as I click on a model in the tree browser on the 
right in GME, a messagebox appears telling:

caption = Object inspector
text = Object inspector could not hand over the project data due to an 
unexpected error. We apologize for the inconvenience.
(this happens roughly once every time I start the plugin again)

one time also happened this:
caption = Model browser
text = Error completing drop operation (0x87650072): The operation 
caused meta violation for object %o

and sometimes also a few other sporadic errors like some "Paradigm 
violation" when I actually did nothing significant....


So I suppose this is not the right way. Is there any way to have the 
plugin running concurrently with GME? If not I can find a workaround... 
luckily in my case I need data from the opened project only at the 
beginning, and then I can exit the plugin with the main thread and just 
leave a secondary thread running which doesn't need any more access to 
the GME project.

Thanks
Gabriele
