- class qgis.gui.QgsFocusWatcher¶
A event filter for watching for focus events on a parent object. Usually QObjects must subclass and override methods like focusOutEvent to handle focus events. Using this class as an event filter avoids the need to subclass objects and the focus events can be directly caught using the emitted signals.
New in version 2.16.
