Thread: GtkStatusIcon not showing icon in the tray !

@Ravi, If you are coding everything properly, then you most likely have to enable the notification area. I think the notification area might come whitelisted by default(If your using Ubuntu.)

You can check by using the gtk_status_icon_is_embedded function. If it returns no then go here and follow the steps.

Here is an example piece of code i threw together. Took me little bit but I learned some stuff in the process.

Code:

#include <gtk/gtk.h>

static void destroy_event(GtkWidget *widget, gpointer data) {
gtk_main_quit();
}

static gboolean delete_event(GtkWidget *widget, GdkEvent *event, gpointer data) {
gtk_main_quit();
return FALSE;
}

static void activate (GtkStatusIcon* status_icon, gpointer user_data) {
g_debug("'activate' signal triggered");
}


//To compile append `pkg-config --cflags --libs gtk+-2.0`
int main( int argc, char *argv[])
{

  GtkWidget *window;
  GtkWidget *image;
  GtkWidget *table;
  GdkPixbuf *pixbuf;
  GtkStatusIcon *status_icon;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size(GTK_WINDOW(window), 230, 150);
  gtk_window_set_title(GTK_WINDOW(window), "Pixbuf Example");
  gtk_window_set_resizable(GTK_WINDOW(window), FALSE);

  table = gtk_table_new(10, 10, TRUE);
  gtk_container_add(GTK_CONTAINER(window), table);
  gtk_widget_show(table);

  pixbuf = gdk_pixbuf_new_from_file("/home/annonymous/Pictures/icon.png", NULL);
  image = gtk_image_new_from_pixbuf(pixbuf);
  //gtk_table_attach_defaults(GTK_TABLE(table), image, 1, 3, 1, 3);
  gtk_widget_show(image);

  status_icon = gtk_status_icon_new_from_pixbuf(pixbuf);
  gtk_status_icon_set_tooltip_text(GTK_STATUS_ICON(status_icon), "This is a tool tip");
  gtk_status_icon_set_visible(status_icon, TRUE);
  //gtk_widget_show(status_icon);
  g_debug("embedded: %s", gtk_status_icon_is_embedded(status_icon) ? "yes" : "no");

  g_signal_connect_swapped(G_OBJECT(window), "destroy-event",
      G_CALLBACK(destroy_event), G_OBJECT(window));

  g_signal_connect_swapped(G_OBJECT(window), "delete-event",
      G_CALLBACK(delete_event), NULL);

  g_signal_connect (G_OBJECT (status_icon), "activate",
      G_CALLBACK (activate), NULL);

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}

Hope this helps.
