Is there a way to tell if a function has been called that has resulted
in a call to the same function?
We have an in-house CRM app that has a function that draws a tabbed
panel on a screen... BUT if there are sub-sub-tabbed panels we want to
invert the tab colors and panel colors...
So...
DrawSubTab($Set) - Black on White
Content
DrawSubTab($Set) - White on Black
Content
DrawSubTab($Set) - Black on White
Content
DrawSubTab($Set) - Black on White
Content
Etc...
I suppose I could rewrite EVERY call to the function with a recursion
count like DrawSubTab($Set,$DepthCount+1) but that would be a MASSIVE
commit... whereas if the function can determine itself... All that
said I can't think of a good way to do it without a bastardized global
variable that track "how deep" we are and there is something that
bothers me about that approach... Unless that really is the easiest
way.
Thanks in advance!
Matt
