Constructor & Destructor Documentation

◆ QgsModelViewToolZoom()

QgsModelViewToolZoom::QgsModelViewToolZoom ( QgsModelGraphicsView * view )

Constructor for QgsModelViewToolZoom.

Definition at line 24 of file qgsmodelviewtoolzoom.cpp.

Member Function Documentation

◆ deactivate()

void QgsModelViewToolZoom::deactivate ( )

overridevirtual

Called when tool is deactivated.

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

Reimplemented from QgsModelViewTool.

Definition at line 128 of file qgsmodelviewtoolzoom.cpp.

◆ keyPressEvent()

void QgsModelViewToolZoom::keyPressEvent ( QKeyEvent * event )

overridevirtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 102 of file qgsmodelviewtoolzoom.cpp.

◆ keyReleaseEvent()

void QgsModelViewToolZoom::keyReleaseEvent ( QKeyEvent * event )

overridevirtual

Key release event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 115 of file qgsmodelviewtoolzoom.cpp.

◆ modelMoveEvent()

void QgsModelViewToolZoom::modelMoveEvent ( QgsModelViewMouseEvent * event )

overridevirtual

Mouse move event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 63 of file qgsmodelviewtoolzoom.cpp.

◆ modelPressEvent()

void QgsModelViewToolZoom::modelPressEvent ( QgsModelViewMouseEvent * event )

overridevirtual

Mouse press 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 33 of file qgsmodelviewtoolzoom.cpp.

◆ modelReleaseEvent()

void QgsModelViewToolZoom::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 74 of file qgsmodelviewtoolzoom.cpp.

Member Data Documentation

◆ mMarqueeZoom

bool QgsModelViewToolZoom::mMarqueeZoom = false

protected
