Re: Unable to capture mouse events of GtkGLArea

[Chris Moller <moller mollerware com>]

Some years ago, I used GtkGlArea in C with:

--------------------------------------------

GtkWidget *gl_area = gtk_gl_area_new ();

gtk_widget_add_events (gl_area, GDK_BUTTON_PRESS_MASK);
g_signal_connect (gl_area, "button-press-event",
                    G_CALLBACK (button_press), molecule);

static gboolean
button_press (GtkWidget *widget,
              GdkEvent  *event,
              gpointer   user_data)
{
  g_print ("button press\n");
}

-------------------------------------------

I'm not all that familiar with Python, but it looks like your code does 
the same thing except possibly that you seem to be setting the event 
mask rather than adding to it.
