Hi,

I would like to display some attributes of semantic element as node's
tooltip. For a start I have overridden in MyEditPart
handleNotificationEvent(Notification notification) method. This way I
can reflect changes in semantic model to tooltip label. It works well,
but I have no idea how to preset tooltip during node's creation. Where
such code should be plugged-in?

Regards,
Seweryn Niemiec

When you need to update some related data structure, like a tooltip,
you'll both need to initialise the data when the edit part is
activated and react when new changes are made. The initialisation is
typically done in the refreshVisuals() method, while you react by
overriding handleNotificationEvent() (as you know). Here's code in an
edit part of mine:
The method for the tooltip is put in its own method, and this method
is called both from refreshVisuals and handleNotificationEvent.

protected void handleNotificationEvent(Notification notification) {
Object feature = notification.getFeature();
if (ModelPackage.eINSTANCE.getComputation_Function().equals(
feature)) {

refreshFunction((ComputationNodeFigure)getNodeFigure());
} else {
super.handleNotificationEvent(notification);
}
}

protected void refreshVisuals() {
super.refreshVisuals();
refreshFunction((ComputationNodeFigure)getNodeFigure());
}

protected void refreshFunction(ComputationNodeFigure nodeFigure) {
Function fun = getFunction();
setFunctionToolTip(nodeFigure, fun);
nodeFigure.setArity(getFunctionArity());
}

Seems this site is down ?

Is the getComputation_Function() method a manually coded method ? I
don't have that in my (generated) model package ...

thx,
Armin

Ok, figured that one out:

Ok, too, these where classes from Hallvard's model, "translated" them to
my own. Now I'm stuck with setFunctionToolTip and the Function class.
Where is that coming from ?

thx,
Armin

That code actually helped and I solved my problem.
