Detailed Description

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.

Note: added in 2.16

Constructor & Destructor Documentation

◆ QgsFocusWatcher()

QgsFocusWatcher::QgsFocusWatcher ( QObject * parent )

explicit

Constructor for QgsFocusWatcher.

Parameters

parent parent widget to catch focus events for. This class will automatically be installed as an event filter for parent.

◆ eventFilter()

bool QgsFocusWatcher::eventFilter	(	QObject *	obj,
		QEvent *	event
	)

overridevirtual

Definition at line 26 of file qgsfocuswatcher.cpp.

◆ focusChanged

void QgsFocusWatcher::focusChanged ( bool focused )

signal

Emitted when parent object's focus changes.

Parameters

focused true if object gained focus, false if object lost focus

◆ focusIn

void QgsFocusWatcher::focusIn ( )

signal

Emitted when parent object gains focus.

◆ focusOut

void QgsFocusWatcher::focusOut ( )

signal

Emitted when parent object loses focus.
