Hi, Wilms. The following C program works as expected:
#include <gtk/gtk.h>
intmain (int argc, char *argv[]){ GtkWidget *window, *darea;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL); g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK(gtk_main_quit), NULL);
darea = gtk_drawing_area_new (); gtk_container_add (GTK_CONTAINER (window), darea);
gtk_widget_set_events (darea, GDK_ENTER_NOTIFY_MASK |GDK_LEAVE_NOTIFY_MASK | GDK_BUTTON_PRESS_MASK |GDK_BUTTON_RELEASE_MASK); g_signal_connect_swapped (G_OBJECT (darea), "enter_notify_event",G_CALLBACK (g_print), "enter_notify_event\n"); g_signal_connect_swapped (G_OBJECT (darea), "leave_notify_event",G_CALLBACK (g_print), "leave_notify_event\n"); g_signal_connect_swapped (G_OBJECT (darea), "button_press_event",G_CALLBACK (g_print), "button_press_event\n"); g_signal_connect_swapped (G_OBJECT (darea), "button_release_event",G_CALLBACK (g_print), "button_release_event\n");
gtk_widget_show_all (window);
gtk_main(); return 0;}
Button click on the drawing area propagates only two events (buttonpress and release). I am using GTK+ 2.12.9. Please try it and tell usyour results.
