Chart Document Controller
The chart document model implements com.sun.star.frame.XModel. Therefore, controllers can be registered with the method connectController()
. When one of the registered controllers is set as current one with setCurrentController()
, this one is also returned in the method getCurrentController()
.
Apart from using the controller directly, there are three other useful methods:
void lockControllers() void unlockControllers() boolean hasControllersLocked()
With a call to lockControllers()
all registered controllers will no longer be notified about changes in the model. If there are changes those are notified no earlier than after calling unlockControllers()
. This is especially useful if you do many changes to the chart model at a time but do not need the view to be updated after every single change. The method hasControllersLocked()
just gives you the state whether controllers are locked or not.
