GDK_IS_WINDOW(event->any.window) fails

[Siddharth Uppal <siddharthuppal yahoo co in>]

Hi,

The test for GDK_IS_WINDOW for the window associated
with an GdkEvent fails in my event handler.

In my app, I hook onto the events like this:
---
    gdk_event_handler_set (main_event_handler, NULL,
NULL);

      gdk_root_add_watch (GDK_POINTER_MOTION_MASK,
root_event_monitor, NULL);

---
Now, when an event occurs, I get the control in my
root_event_monitor. root_event_monitor() is defined
as:

static GdkFilterReturn
root_event_monitor (GdkXEvent *gdk_xevent,
                    GdkEvent  *event,
                    gpointer   gdk_root)
{
  // do something

  Here the test GDK_IS_WINDOW(event->any.window)
passes!
}

And, when I get control in main_event_handler, defined
as:

static void
main_event_handler (GdkEvent *event,
                    gpointer  data)
{
     // do something...

     Here the test GDK_IS_WINDOW(event->any.window)
fails!
}

What can explain this behavior?

Regards,
Siddharth
