Re: Gtk Container add

[Victor Vicente <drzoidberg wanadoo es>]

If you want to create an app with three buttons, that contains a pixmap every 
one, you must do something like this

main_window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
box = gtk_hbox_new (FALSE, 0);

for (i=0; i<NUM_BUTTONS; i++)
{
  button[i] = gtk_button_new ();
  pixmap[i] = gtk_pixmap_new (pixmap, mask);
  gtk_container_add (GTK_CONTAINER (button[i]), pixmap[i]);

  gtk_box_pack_start (GTK_BOX (box), button[i], FALSE, FALSE, 0);
}

gtk_container_add (GTK_CONTAINER (main_window), box);
gtk_widget_show_all (main_window);



In your example, I think you're using the same variable for all the buttons, 
and you've to declare a variable for each one.

Im creating an app with 3 buttons.. and each button will show something.
Each button have a pixmap (created it with gimp) and I have a window
(with TOP_LEVEL), also I add a box to this window (with a
gtk_container_add). The problem starts when I add the image to the
button:


  image = gtk_pixmap_new(pixmap, mask);
  gtk_widget_show (image);
  gtk_container_add(GTK_CONTAINER (button), image);


When I create a second gtk_Container_add, I get this:


Gtk-CRITICAL **: file gtkbin.c: line 217 (gtk_bin_add): assertion
`bin->child == NULL' failed.


How could I solve this?.. killing the other container, or what?.
