Is there a way to send some user-defined value while creating a gtk-window??

Hi,

I need to send some user-defined value (say some integer) along with the gtk window creation api.

So that i can differentiate that particular window from other windows and use that user-defined integer to change the way how the window pixmap gets created in X11 backend?

Does gtk provide such mechanism to pass additional parameters in the window create/allocation api?
