pan cancels WindowKeyPressFcn callback...

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

Thanks!

Actually I tried the "Jedi Mind Trick" that you suggest in the other thread . My code is now

function someFunction

Fig = figure();

plot(rand(1,10))

addlistener(Fig, 'WindowKeyPress', @keyPress);

pan on

function keyPress(src,evtData)

key = get(src,'CurrentCharacter')

end

end

Now I can capture the key that was pressed, but still the figure disappears after I press a key and I get back to Matlab command window...

Any further suggestions?

Thanks,

Razvan

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.

I know this is an old thread but it helped me out. In addition to step 3) I also have to set KeyPressFcn = [] to avoid keystrokes getting back to Matlab command window.

Thanks
