[maemo-developers] Empty menu with GtkMenuToolButton

[From: Konrad Anton]

Hello all,

I'm trying to use a GtkToolButton to get a pop-up menu popping up from 
the toolbar.

The following example shows the problem I'm experiencing: the toolbar is 
correctly populated with one toolbutton and one arrow to the right of 
it, but when I click the arrow, an empty menu pops up (a square of 
roughly 30 pixels, surrounded by a menuish frame). The size of the 
square seems not to be influenced by how many menu entries I create.

//------------------------------------
#include <gtk/gtk.h>
#include <hildon/hildon-program.h>
#include <hildon/hildon-banner.h>

int main(int argc, char** argv) {
   gtk_init(&argc, &argv);
   HildonProgram* program = HILDON_PROGRAM(hildon_program_get_instance());
   HildonWindow* main_window = HILDON_WINDOW(hildon_window_new());
   hildon_program_add_window(program, main_window);

   GtkToolbar*  toolbar = GTK_TOOLBAR(gtk_toolbar_new());
   GtkMenu* toolbar_popup_menu = GTK_MENU(gtk_menu_new());

   GtkWidget* menu_item = gtk_menu_item_new_with_label("Sausage");
   gtk_menu_shell_append(GTK_MENU_SHELL(toolbar_popup_menu), menu_item);
   // same effect with:
   // gtk_container_add(GTK_CONTAINER(toolbar_popup_menu), menu_item);

   GtkToolItem* popup_toolbutton =
     gtk_menu_tool_button_new_from_stock(GTK_STOCK_COPY);

   gtk_menu_tool_button_set_menu(GTK_MENU_TOOL_BUTTON(popup_toolbutton),
				GTK_WIDGET(toolbar_popup_menu));
   gtk_toolbar_insert(toolbar, popup_toolbutton, -1);

   hildon_window_add_toolbar(main_window, GTK_TOOLBAR(toolbar));
   gtk_widget_show_all(GTK_WIDGET(main_window));
   // gtk_widget_show_all(GTK_WIDGET(toolbar)); -- no improvement

   gtk_main();
   return 0;
}
//-------------------------

I probably just missed a call to gtk_bla_set_blub() somewhere, but I 
can't figure out correct values for bla and blub. Any help would be 
appreciated.
