Detailed Description
A mode where click+dragging on the background rubber-band selects nodes.
This mode does not select arcs.
- See also
- qtDisconnectMode to select arcs.
Member Function Documentation
◆ enterMode()
|
overrideprotectedvirtual |
This method is called by the diagram as the mode is being changed to this class.
Subclasses should override this method to prepare the scene (such as enabling/disabling items in the scene, adding items to be drawn while the mode is active, etc.)
Reimplemented from smtk::extension::qtDiagramViewMode.
◆ exitMode()
|
overrideprotectedvirtual |
This method is called by the diagram as the mode is being changed away from this class.
Subclasses should override this method to prepare the scene (such as enabling/disabling items in the scene, removing items drawn while the mode was active, etc.)
Reimplemented from smtk::extension::qtDiagramViewMode.
