Sets the function to call to handle all events from GDK.
Usage
gdkEventHandlerSet(func, data)
Arguments
func
[GdkEventFunc] the function to call to handle events from GDK.
data
[R object] 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+.)
