refreshing/repainting figures in a diagram [message #822232]

Hello everyone,

i have a wrapping label in a compartment and i want to associate it with a model property. I solved this by subclassing the GraphicalEditPolicy, which sends a GEF command that sets the new value manually after selecting it from the property sheet. This works fine but the new value isn't visible before performing an action on the figure, like dragging or collapsing it. My question is how can i convince GMF to refresh the figure (the editpart which contains the label) or also the whole diagram.

regards
bj

Hi,

you can override the notifyChanged in your EditPart like this:

@Override
public void notifyChanged(Notification notification) {
   super.notifyChanged(notification);
   if (notification.getFeature() == MyPackage.Literals.MY_TEXT_FEATURE) {
       // Update the label text
	getLabel().setText(resolveSemanticElement().getText());
   }
}

Regards,
Andreas
