| void | diagramAboutToBeDestroyed (AbstractDiagram *diagram) |
| Emitted when a diagram is being destroyed, but before its data is invalidated. | |
| void | diagramAttributesChanged (AbstractDiagram *diagram) |
| This signal is emitted whenever the attributes of the diagram change. | |
| void | diagramDataChanged (AbstractDiagram *diagram) |
| This signal is emitted whenever the data of the diagram changes. | |
| void | diagramDataHidden (AbstractDiagram *diagram) |
| This signal is emitted whenever any of the data of the diagram was set (un)hidden. | |
| void | diagramDestroyed (AbstractDiagram *diagram) |
| This signal is emitted immediately before the diagram is being destroyed. | |
