With update interval set to 500ms:
when we hover the mouse over, we can see tooltips:
With update interval below 500ms (eg: 490), no tooltip is shown.
No tooltip is shown for update interval below 500ms.
My wild guess here is that the tool tip delay is 500ms, and updating the applet faster, disturbs the tool tip trigger, so it never happens.

Your guess is correct. Tooltip will no longer work when the time is less than 500 milliseconds.This is my test example:
static int count; static gboolean update_button_tooltip (GtkWidget *button) { char *tooltip_text; tooltip_text = g_strdup_printf ("This is the %dth test", count), gtk_widget_set_tooltip_text (button, tooltip_text); g_free (tooltip_text); count ++; return TRUE; } int main (int argc,char *argv[]) { GtkWidget *window; GtkWidget *box; GtkWidget *button; gtk_init (&argc,&argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_default_size (GTK_WINDOW (window), 350, 220); g_signal_connect ((window), "delete_event", G_CALLBACK (gtk_main_quit), NULL); box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 2); gtk_container_add (GTK_CONTAINER (window), box); button = gtk_button_new_with_label ("test"); gtk_box_pack_start (GTK_BOX (box), button, FALSE, FALSE, 6); g_timeout_add (500, (GSourceFunc) update_button_tooltip, button);
So this is a problem with GTK

Expected behaviour
With update interval set to 500ms:
when we hover the mouse over, we can see tooltips:
With update interval below 500ms (eg: 490), no tooltip is shown.
Actual behaviour
No tooltip is shown for update interval below 500ms.
Steps to reproduce the behaviour
My wild guess here is that the tool tip delay is 500ms, and updating the applet faster, disturbs the tool tip trigger, so it never happens.
