Constructor & Destructor Documentation

◆ QgsLayoutViewToolTemporaryKeyZoom()

Member Function Documentation

◆ activate()

void QgsLayoutViewToolTemporaryKeyZoom::activate ( )
overridevirtual

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

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

Reimplemented from QgsLayoutViewTool.

Definition at line 99 of file qgslayoutviewtooltemporarykeyzoom.cpp.

◆ keyPressEvent()

void QgsLayoutViewToolTemporaryKeyZoom::keyPressEvent ( QKeyEvent *  event)
overridevirtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 38 of file qgslayoutviewtooltemporarykeyzoom.cpp.

◆ keyReleaseEvent()

void QgsLayoutViewToolTemporaryKeyZoom::keyReleaseEvent ( QKeyEvent *  event)
overridevirtual

Key release event for overriding.

Default implementation does nothing.

Reimplemented from QgsLayoutViewTool.

Definition at line 71 of file qgslayoutviewtooltemporarykeyzoom.cpp.

◆ layoutReleaseEvent()

void QgsLayoutViewToolTemporaryKeyZoom::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 27 of file qgslayoutviewtooltemporarykeyzoom.cpp.
