Sets the function to call to handle all events from GDK.
Usage
gdkEventHandlerSet(func, data)
Arguments
func
the function to call to handle events from GDK.
data
user data to pass to the function.
Details
Note that GTK+ uses this to install its own event handler, so it is
usually not useful for GTK+ applications. (Although an application
can call this function then call gtkMainDoEvent to pass
events to GTK+.)
