[bug] in showing windows (was: Re: gtk-timj-970919.patch) (fwd)

[Tim Janik <Tim Janik Hamburg Netsurf DE>]

hi all,

apended is a message i got from Dan Stromberg regarding a problem
with showing windows in gtk...

i played a little with his source and found this out:



#include <gtk/gtk.h>
#include <string.h>

/* defines for PLACE:
 * 1) window size: 200x200, fully filled with a button that says "foo"
 * 2) window size: 200x200, totaly empty
 * 3) window size: ca 15x21 (font dependent), button "foo" in it
*/
#define PLACE    1

int main (int argc, char *argv[])
   {
   GtkWidget *window;
   GtkWidget *button;
   GtkWidget *box;

   gtk_init (&argc, &argv);

   window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
   
#if PLACE == 1
   gtk_widget_show (window);
#endif
   
   box = gtk_vbox_new (FALSE, 0);
   

   gtk_widget_show (GTK_WIDGET (box));
   gtk_container_add (GTK_CONTAINER (window), box);

#if PLACE == 2
   gtk_widget_show (window);
#endif

   button = gtk_button_new_with_label("foo");
   gtk_widget_show(button);
   
   gtk_container_add (GTK_CONTAINER (box), button);
   
#if PLACE == 3
   gtk_widget_show (window);
#endif

   gtk_main ();
   return 0;
   }



strange isn't it?

Thanks.

I'm glad you asked.

BTW, I sent a message about this to the list earlier, but it apparently
didn't make it thru the list server.

Below are two programs.  The first works with gtk+970828, but not
gtk+970916.  The second program is similar to the first, but works with
both of these gtk releases.

In short, it appears that a button within a table within a box within a
window has problems (the button's label isn't visible), but a button
within a table within a window is ok.
