FilterFunc


Description:

[ CCode ( instance_pos = 2.9 ) ]
public delegate FilterReturn FilterFunc (XEvent xevent, Event event)

Specifies the type of function used to filter native events before they are converted to GDK events.

When a filter is called, event is unpopulated, except for `event->window`. The filter may translate the native event to a GDK event and store the result in event, or handle it without translation. If the filter translates the event and processing should continue, it should return gdk_filter_translate.

Parameters:

xevent

the native event to filter.

event

the GDK event to which the X event will be translated.

data

user data set when the filter was installed.

Returns:

a FilterReturn value.
