Hi, I have a little problem with gmf.

I have found how to create nodes programmatically and it works but now I want to create connection between these nodes alors programmatically but I can't find where to do it and how to do it.

To understand what I want to do :

I create a node A which create automatically a node B and a node C, I need a connection between A and B and between A and C.

Another little question, after creating nodes B and C automatically, how to place them near A ? They are always top left at this time.

I don't know what I do wrong :

if(getArchi()==null){
	getComponent().setArchitecture((MuArchitecture)getComponent().eContainer());
	getArchi().getComponents().add(getComponent());
}
if(getComponent().getProvided()==null){
	InterfaceP interf = new MuadlFactoryImpl().createInterfaceP();
	interf.setArchiIP(getArchi());
	interf.setProvider(getComponent());
	getComponent().setProvided(interf);
	getArchi().getProviders().add(interf);
}
if(getComponent().getRequired()==null){
	InterfaceR interf = new MuadlFactoryImpl().createInterfaceR();
	interf.setArchiIR(getArchi());
	interf.setRequirer(getComponent());
	getComponent().setRequired(interf);
	getArchi().getRequirers().add(interf);
				}

I explain a little more :

I have an architecture with inside components, when I create a component, the code creates an InterfaceP and an InterfaceR, I add the two interfaces into my architecture then I link the interfaces with the component with require et provide but I have no connections between them...

Hi Alzago,

I found the GMF Tutorial Part 3 very useful when trying to achieve something similar.

If you look at the use of the DeferredCreateConnectionViewAndElementCommand

(http://wiki.eclipse.org/GMF_Tutorial_Part_3#Custom_Actions)

This will guide you in the right direction I think.

Well, I have found how to create the node and the connection outside the container (muarchitecture) but when I do the same thing into the container, the connection is invisible.

I don't know why and what to do to fix that.

New evolution ! The connection is created but I can't see it, I need to close the diagram et reopen it to see it.

I think I need to refresh something after the link is created. Now need to know how to do it.

hi, is it possible to explain me, how to create a node and a connection programmatically? I need to create a Node A, which connects to a Node B, maybe it should connect to a node C, D, E, F,....

Thanks
Thomas
