global variables in IDL [message #28655] Tue, 25 December 2001 05:57

Hi,

I want to keep some global variables in an IDL program containing different
widgets without having to pass the variables each time a new base widget is
created. It can be done with common blocks, but then you can have only 1
instance of the program running.
I was thinking of creating a widget (called Globals) and copy the variables
in a struct to its uvalue. If another widget then wants these variables, I
need to get a widget identifier to Globals and retrieve the struct. But how
can I get this widget identifier?
Any help is appreciated...

Gert
