Constructor for QgsLayoutViewToolZoom.

Member Function Documentation

void QgsLayoutViewToolZoom::deactivate ( )

overridevirtual

Called when tool is deactivated.

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

Reimplemented from QgsLayoutViewTool.

Definition at line 131 of file qgslayoutviewtoolzoom.cpp.

void QgsLayoutViewToolZoom::keyPressEvent ( QKeyEvent *  event )

overridevirtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 105 of file qgslayoutviewtoolzoom.cpp.

void QgsLayoutViewToolZoom::keyReleaseEvent ( QKeyEvent *  event )

overridevirtual

Key release event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 118 of file qgslayoutviewtoolzoom.cpp.

void QgsLayoutViewToolZoom::layoutMoveEvent ( QgsLayoutViewMouseEvent *  event )

overridevirtual

Mouse move event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 64 of file qgslayoutviewtoolzoom.cpp.

void QgsLayoutViewToolZoom::layoutPressEvent ( QgsLayoutViewMouseEvent *  event )

overridevirtual

Mouse press event for overriding.

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

Reimplemented from QgsLayoutViewTool.

Definition at line 32 of file qgslayoutviewtoolzoom.cpp.

void QgsLayoutViewToolZoom::layoutReleaseEvent ( QgsLayoutViewMouseEvent *  event )

overridevirtual

Mouse release event for overriding.

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

Reimplemented from QgsLayoutViewTool.

Definition at line 75 of file qgslayoutviewtoolzoom.cpp.
