Member Function Documentation

◆ allowItemInteraction()

bool QgsModelViewToolSelect::allowItemInteraction ( )

overridevirtual

Returns true if the tool allows interaction with component graphic items.

Reimplemented from QgsModelViewTool.

Definition at line 341 of file qgsmodelviewtoolselect.cpp.

◆ deactivate()

void QgsModelViewToolSelect::deactivate ( )

overridevirtual

Called when tool is deactivated.

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

Reimplemented from QgsModelViewTool.

Definition at line 331 of file qgsmodelviewtoolselect.cpp.

◆ keyPressEvent()

void QgsModelViewToolSelect::keyPressEvent ( QKeyEvent * event )

overridevirtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 319 of file qgsmodelviewtoolselect.cpp.

◆ modelDoubleClickEvent()

void QgsModelViewToolSelect::modelDoubleClickEvent ( QgsModelViewMouseEvent * event )

overridevirtual

Mouse double-click event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 203 of file qgsmodelviewtoolselect.cpp.

◆ modelMoveEvent()

void QgsModelViewToolSelect::modelMoveEvent ( QgsModelViewMouseEvent * event )

overridevirtual

Mouse move event for overriding.

Default implementation does nothing.

Reimplemented from QgsModelViewTool.

Definition at line 145 of file qgsmodelviewtoolselect.cpp.

◆ modelPressEvent()

void QgsModelViewToolSelect::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 47 of file qgsmodelviewtoolselect.cpp.

◆ modelReleaseEvent()

void QgsModelViewToolSelect::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 222 of file qgsmodelviewtoolselect.cpp.

◆ mouseHandles()

QgsModelViewMouseHandles * QgsModelViewToolSelect::mouseHandles ( )

Returns the view's mouse handles.

Definition at line 346 of file qgsmodelviewtoolselect.cpp.

◆ resetCache()

void QgsModelViewToolSelect::resetCache ( )

Resets the internal cache following a scene change.

Definition at line 364 of file qgsmodelviewtoolselect.cpp.

◆ setScene()

void QgsModelViewToolSelect::setScene ( QgsModelGraphicsScene * scene )

Sets the a scene.

Definition at line 351 of file qgsmodelviewtoolselect.cpp.

◆ wheelEvent()

void QgsModelViewToolSelect::wheelEvent ( QWheelEvent * event )
