Hi everyone,
I want to insert a new model element into the model during the execution of a RecordingCommand and then have it selected in the diagram.
Until now I managed to create the model element, then have it positioned in a org.eclipse.gmf.runtime.notation.Diagram. As I understand it, the selection is done by the org.eclipse.gef.GraphicalViewer. The viewer does not update its ShapeNodeEditParts until after the command is executed and the TransactionalEditingDomain commited.
Is there a way to write such a command?
Best regards,
Erich

Yes, in your RecordingCommand you can either invoke a Runnable on the Display or schedule a Job to select the figure.
This is an example for the Runnable:
Display display = PlatfromUI.getWorkbench().getDisplay();
display.asyncExec(new Runnable() {
public void run() {
// your code to select a figure goes here
}
});
This is an example for the UIJob:
Job job = new UIJob("Select figure") {
public IStatus runInUIThread(IProgressMonitor monitor) {
// your code to select a figure goes here
return Status.OK_STATUS;
}
});
job.schedule(50); // schedule after 50 ms
Beware, however, that Commands are undoable and the Runnable/Job will be executed during undo operations, too, if you don't prevent this.
