Commands triggered by a key stroke [message #248612]

Hi,

I want to execute a command triggered by a key stroke. This command will
create a child figure and only could be triggered if the parent figure is
selected.

what would be the better way to do that?

I've been thinking to addKeyListener to the parent figure, but I suppose
that the command should be instantiated in the apropiated EditPart.

Any idea?

Thank you in advance.

Should I have to add a keyHandler to EditPartViewer?

How is used the addKeyListener in figures?

Thanks

Yes, you'll want a KeyHandler set on your EditPartViewer. Then you can
map an IAction to a particular keystroke using:

org.eclipse.gef.KeyHandler.put(KeyStroke keystroke, IAction action)

Your Action would take care of executing the command on the command stack.

For a full example, check out how the DeleteAction is hooked into the
Logic example.

Regards,
Ben
