If this is not appropriate for this newsgroup I apologize in advance, please
direct me to the appropriate group...

I have created a canvas object and set it as the current displayable in the
current display. The command listner is the class that I created and called
the canvas object from. I added commands to the canvas, to be caught by the
commandListener (which is set to the class that created the canvas). The
problem is this... Since I registered and added the exit command, a 'soft'
command, it is caught and it works correctly.... If I press a number key, it
is caught by the canvas object... If I want to press a number key, and have
it 'appear' to execute a function that is part of the calling class
(basically be caught by the command listener as does the exit 'softkey'....
how do I do this? I suspect that it would be something like this...

  protected void keyPressed(int keyCode) {
           if (keyCode == 1) {
                   'classThatCreatedThisCanvas'.doWhatIWant();
             }
     }

In the end, I just want to give control back to where it was before the
canvas so that I can create other canvases and set them as the current
displayable

THANKS SO MUCH FOR THE HELP.

Jason Wolfe.
