How to add figures programmatically [message #162448]

Hi,

I'd like to programmatically add figures to the diagram using the
commands that GEF uses.

How can I add an AbstractGraphicalEditPart to the diagram without using
the palette to manually add an edit part. I'd like to use the same
commands (extending org.eclipse.gef.commands.Command) that would be
returned from the various methods of XYLayoutEditPolicy.

I know how to create a command, but don't know what to do with it in my
action.

I'd be very happy if someone could help me put editparts into the
diagram from within an action.

Thanks in advance for any hint,

Christian

One nice thing about Eclipse is that you can follow the call path into the
GEF source if you need to. Following the call path for
EditPart.getCommand(...) you end up in AbstractTool.executeCurrentCommand()
which points you to the CommandStack which is retrieved from the EditDomain.
So at the end of the day you just need to:

commandStack.execute(yourCommand);

Thanks Rob. That seems to work, however, I don't know whether this is a
good solution.

But thanks anyway.

Hi,

Why not just create the command programmatically because there is no
tools invoked by user activity? Maybe it is better to bother less objects.
