Re: Problems with gtk_menu_popup

[Santhosh <santhosh lists gmail com>]

Hi Boromir,
    The "GtkVBox" widget will not receive any events .. So you need to
pack a event box inside the GtkVBox...

The following piece of code do the job for u..

#include<gtk/gtk.h>
#include"unistd.h"
#include"sys/types.h"
#include"sys/wait.h"

int end_program(GtkWidget *widget,gpointer data)
{
   gtk_main_quit();
   return 0;
}

int startsw(GtkWidget *widget,gpointer data)
{
   pid_t pid;

   if((pid= fork()) < 0)
       printf("Fork Error!");
   else if(pid == 0)
   {
      if(execl("/usr/bin/gaim",NULL)==-1) {
          printf("child exec failed");
      }

      exit(127);
   }

   return 0;
}

static int menuitem_resp(GtkWidget *widget,GdkEvent *event)
{
    if (event->type == GDK_BUTTON_PRESS) {
                GdkEventButton *bevent = (GdkEventButton *) event;
                        gtk_menu_popup (GTK_MENU (widget), NULL, NULL,
NULL, NULL,
bevent->button, bevent->time);
               return TRUE;
                                    }
        return FALSE;
}

static void resp(gchar *string)
{
   printf("%s\n",string);
}

int main(int argc,char *argv[])
{
  char buf[128];
  GtkWidget  *menu_items;
  GtkWidget  *window;
  GtkWidget  *button;
  GtkWidget  *vbox;
  GtkWidget  *menu;
  GtkWidget  *root_menu;
  GtkWidget* ev_box; /* added */

  int i=0;

  gtk_init(&argc,&argv);

  window =
g_object_new(GTK_TYPE_WINDOW,"default-height",100,"default-width",500,"border-width",12,"title","DashBoard",NULL);

  g_signal_connect(window,"destroy",G_CALLBACK(end_program),NULL);

  menu = gtk_menu_new();

  for(i=0;i<3; ++i)
  {
      sprintf (buf, "Test-undermenu - %d", i);
      menu_items = gtk_menu_item_new_with_label (buf);
      gtk_menu_shell_append (GTK_MENU_SHELL (menu), menu_items);
      g_signal_connect_swapped (G_OBJECT (menu_items),
"activate",G_CALLBACK (resp),(gpointer) g_strdup(buf));

      gtk_widget_show (menu_items);
  }

     vbox = gtk_vbox_new (FALSE, 0);
     gtk_container_add (GTK_CONTAINER (window), vbox);
     gtk_widget_show (vbox);

   /* create event box and pack it in vbox */
  ev_box = gtk_event_box_new ();
  gtk_container_add (GTK_CONTAINER (vbox), ev_box);
  gtk_widget_show_all (GTK_WIDGET (vbox));
  
/* connect the  "event" to the EventBox Widget */
g_signal_connect_swapped(G_OBJECT(ev_box),"event",G_CALLBACK(menuitem_resp),G_OBJECT(menu));
  gtk_widget_show_all(GTK_WIDGET(window));

  gtk_main();

  return 0;
}
