Re: [gtk-list] Re: gtk draw shadow ?

["Donna S. Martin" <donna omartin com>]

gtk_draw_shadow  (preview->style,preview->window,
       GTK_STATE_NORMAL,
       GTK_SHADOW_OUT,0,0,32,32);

You have to send it a window...but the window id of preview
isn't valid yet. preview has to be realized before the window
id is valid, it's NULL until then...thus the error you are seeing.
(The widget id is valid, but a window id hasn't yet been assigned).

(I think the suggestion to add a frame is a good one, since it handles the
outline for you, and stays at the widget level.....)

HTH,
Donna
