Hi,
I noticed that after using the pan function, WindowKeyPressFcn callback doesn't work anymore...
Example:
function someFunction
Fig = figure('WindowKeyPressFcn', @buttonPressed_Callback);
plot(rand(1,10))
pan on
function buttonPressed_Callback(handle, event)
key = event.Key
end
end
How can I reactivate the WindowKeyPressFcn callback after the pan command?
Thanks,
Razvan

You are correct, pan does have that effect. Please see http://www.mathworks.com/matlabcentral/answers/30563-pan-mode-control-via-keyboard

1) *First* turn on pan.
2) Then turn off the listeners as shown at https://groups.google.com/group/comp.soft-sys.matlab/msg/db42cf51392b442a
3) Then set() your desired function as the WindowKeyPress callback.
4) When it is time to turn pan off, reverse the order: set() the WindowKeyPress callback to what it would normally be, then re-enable the listeners, then turn pan off.
addlistener() is not involved in this process: you need to disable the listeners instead as the listeners are blocking you from adding your own WindowKeyPress callback.
