Hello all,

I am new to GMF .We have a requirement where we hide/unhide details for
the domain model elements represented in diagram based on user action i,e

We have rectangle object representing the domain model element it has
input and output model element affixed to the rectangle border where
(input/output details) are represented by small circle. On user action to
see only input details i would like to hide all the output details.(To
hide all the output circle)

Can i know what is the best way to achive this ?

Regards
BG

I do not know about any snipets for this.

For exmaple - by traversing whole diagram structure from the top down to
the ports.

I was able to create a command to hide the view based using attribute
CompositeCommand cc = new CompositeCommand("Diagram_settings");

BorderedBorderItemEditPart compShapeEditPart =
(BorderedBorderItemEditPart)object;
View hostView =(View)compShapeEditPart.getModel();
cc.add(new ShowHidePortsCommand(editingDomain,hostView,true));

when i do hide all or unhide all it working fine but when try to hide some
port node in this case let us take to hide all inport port and all unhide
outport then it is not refreshing correctly elements i.e hide is working
fine but unhide ports are not appearing back on editor if debug i can see
the view.setVisible(true) but still it not visible ?

PS :here my port object node is represented by image.

I had a similar problem. To solve the problem, inside the
BorderedShapeEditPart (the parent), I overwrote
#handleNotificationEvent(Notification event). Now, it only refreshes the
child EditPart, which visibility has changed:

if (NotationPackage.eINSTANCE.getView_Visible().equals(
event.getFeature())) {
Node node = (Node) event.getNotifier();
refreshChild((GraphicalEditPart)getChildBySemanticHint(
node.getType()));
}
else {
super.handleNotificationEvent(event);
}
