Member Function Documentation
◆ 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()
|
overridevirtual |
Key press event for overriding.
Default implementation does nothing.
Reimplemented from QgsModelViewTool.
Definition at line 102 of file qgsmodelviewtoolzoom.cpp.
◆ keyReleaseEvent()
|
overridevirtual |
Key release event for overriding.
Default implementation does nothing.
Reimplemented from QgsModelViewTool.
Definition at line 115 of file qgsmodelviewtoolzoom.cpp.
◆ modelMoveEvent()
|
overridevirtual |
Mouse move event for overriding.
Default implementation does nothing.
Reimplemented from QgsModelViewTool.
Definition at line 63 of file qgsmodelviewtoolzoom.cpp.
◆ modelPressEvent()
|
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()
|
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.
