Hi,

I'm using Xtext and GMF and therefor I would like to acces the current selected node in my xtext project in order to get the child of this node exported.

index.php/fa/15066/0/

For exampple if Super Class 1 is selected, I want to acces this class in my xtext project to get the childs B and C. Is there a way to do this?

Hi,

thanks for the hint. I tried to implement the selection service, but it didn't seems to acces the GMF related node. Rather that I get an xtext class object, because I implmented an IXtextAwareEditPart in GMF. Is there a way to acces the active GMF node?
This code hasn't work for me so far:

ISelectionService selectionService = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getSelectionService();
ISelection selection = selectionService.getSelection();
if (selection instanceof IStructuredSelection) {
	IStructuredSelection iStructuredSelection = (IStructuredSelection) selection;
	if (iStructuredSelection.getFirstElement() instanceof PartImpl) {
		PartImpl partImpl = (PartImpl) iStructuredSelection;  // <------ The xtext class
	}
}
