Re: How to get GdkNativeWindow from GdkWindow? (need during iteration of display, using gdk)

[Mike Cookson <cook60020tmp mail ru>]

Not sure, is it correct way... i found gdk_x11_drawable_get_xid (), which takes GdkDrawable pointer and returns XID. I guess, it is same as GdkNativeWindow, right?

But even so, GdkNativeWindow is not associated with only one windowing system (HWND on m$ win), and so, it would be nice, to have more generic way to get it.
