Constructor & Destructor Documentation

◆ QgsLayoutViewToolZoom()

QgsLayoutViewToolZoom::QgsLayoutViewToolZoom ( QgsLayoutView * view )

Constructor for QgsLayoutViewToolZoom.

Definition at line 23 of file qgslayoutviewtoolzoom.cpp.

Member Function Documentation

◆ deactivate()

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 136 of file qgslayoutviewtoolzoom.cpp.

◆ keyPressEvent()

void QgsLayoutViewToolZoom::keyPressEvent ( QKeyEvent * event )

overridevirtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 110 of file qgslayoutviewtoolzoom.cpp.

◆ keyReleaseEvent()

void QgsLayoutViewToolZoom::keyReleaseEvent ( QKeyEvent * event )

overridevirtual

Key release event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 123 of file qgslayoutviewtoolzoom.cpp.

◆ layoutMoveEvent()

void QgsLayoutViewToolZoom::layoutMoveEvent ( QgsLayoutViewMouseEvent * event )

overridevirtual

Mouse move event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 69 of file qgslayoutviewtoolzoom.cpp.

◆ layoutPressEvent()

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.

◆ layoutReleaseEvent()

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 80 of file qgslayoutviewtoolzoom.cpp.
