Re: [gtk-list] gdk_color_alloc memory leak?

[Patrick Paysant <Maf-Comp wanadoo fr>]

Hi Douglas

I have the same problem as yours with gtk+-1.0.6. It seems it is either a too
difficult problem or a too easy one as it's not the first time this appears in
this mail-list. And as I never see any response...
I'm using GdkGC to have lot of different colors, so each time I make a
"gdk_gc_new" then I tried unref, destroy, free, ... Nothing that works.
My app refresh every seconds, so there is rapidly a great amount of memory
used ! (+4 ko each time !!!)

It's not helping but you're not alone   ;-)

Patrick

P.S.: sorry for my bad english
