Constructor for QgsModelViewToolTemporaryKeyZoom.

Member Function Documentation

◆ activate()

void QgsModelViewToolTemporaryKeyZoom::activate ( )

overridevirtual

Called when tool is set as the currently active model tool.

Overridden implementations must take care to call the base class implementation.

Reimplemented from QgsModelViewTool.

Definition at line 100 of file qgsmodelviewtooltemporarykeyzoom.cpp.

◆ keyPressEvent()

void QgsModelViewToolTemporaryKeyZoom::keyPressEvent ( QKeyEvent * event )

overridevirtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 39 of file qgsmodelviewtooltemporarykeyzoom.cpp.

◆ keyReleaseEvent()

void QgsModelViewToolTemporaryKeyZoom::keyReleaseEvent ( QKeyEvent * event )

overridevirtual

Key release event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 72 of file qgsmodelviewtooltemporarykeyzoom.cpp.

◆ modelReleaseEvent()

void QgsModelViewToolTemporaryKeyZoom::modelReleaseEvent ( QgsModelViewMouseEvent * event )

overridevirtual

Mouse release event for overriding.

Default implementation does nothing. Note that subclasses must ensure that they correctly handle cases when a modelPressEvent is called without a corresponding modelReleaseEvent (e.g. due to tool being changed mid way through a press-release operation).

Reimplemented from QgsModelViewTool.

Definition at line 28 of file qgsmodelviewtooltemporarykeyzoom.cpp.
