Class: QgsFocusWatcher

class qgis.gui.QgsFocusWatcher

Bases: PyQt5.QtCore.QObject

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.

QgsFocusWatcher(parent: QObject) Constructor for QgsFocusWatcher.

Parameters

parent

parent widget to catch focus events for. This class will automatically be

installed as an event filter for parent.

focusChanged

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

Parameters
  • name (str = ...) –

  • revision (int = ...) –

  • arguments (Sequence = ...) –

Return type

PYQT_SIGNAL
