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 101 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 40 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 73 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 29 of file qgsmodelviewtooltemporarykeyzoom.cpp.
