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 131 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 105 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 118 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 64 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 75 of file qgslayoutviewtoolzoom.cpp.

Member Data Documentation

◆ mMarqueeZoom

bool QgsLayoutViewToolZoom::mMarqueeZoom = false
