Hello,

I hope this thread does not exist already and I wish this optional parameter for window:

FreeGadget(#PB_All [, Window])

Posted: **Sun Nov 08, 2015 11:37 pm**

Would that even be possible if one is using #PB_Any for creation of gadgets?

I was about to write the same feature request, so +1 from me.

Such a parameter is very handy, if a programm creates and destroy different gadget-layouts on the same window during runtime.
