Detailed Description

Functions that deal with the freezing of event processing of an evas.

Function Documentation

EAPI void evas_event_freeze (Evas * e)

Freeze all event processing. Parameters:

e The canvas to freeze event processing on.

This function will indicate to evas that the canvas e is to have all event processing frozen until a matching evas_event_thaw() function is called on the same canvas. Every freeze call must be matched by a thaw call in order to completely thaw out a canvas.

Example:

  extern Evas *evas;
  extern Evas_Object *object;
 
  evas_event_freeze(evas);
  evas_object_move(object, 50, 100);
  evas_object_resize(object, 200, 200);
  evas_event_thaw(evas);
 
 

 

EAPI void evas_event_thaw (Evas * e)

Thaw a canvas out after freezing. Parameters:

e The canvas to thaw out.

This will thaw out a canvas after a matching evas_event_freeze() call. If this call completely thaws out a canvas, events will start being processed again after this call, but this call will not invole any 'missed' events to be evaluated.

See evas_event_freeze() for an example.
