Hi! I have a problem. If I set command "pan" in the KeypressFcn of a GUI, so that I can use a key to control the pan mode (e.g. "P"). If the pan mode is not on, there is no problem to activate the pan mode. But if I press the key again, then the KeypressFcn will no more be invoked.
If there anyway to let the key alway control Pan on and Pan off?
Thanks

Yes, there is, by infiltrating the listener.

You turn on pan, you use the Jedi Mind Trick on the listeners, you install a new key press callback. The new key press callback handles everything the regular callback would but also looks for 'p' and if it finds it then then it removes the trick callback and wakes up the listeners and turns pan off.
