hide notification

[howud...@gmail.com]

I can override onShow or cal addShowListener() in order to know when a form is being displayed.  I use this to start a timer.  I'd like to cancel the timer when the form is not visible (ie user went home, or turned the display off, or selected another form).  How can I do this?

If you use UITimer it will not invoke if the form is hidden. However it will keep counting down so it might invoke immediately if the form is shown.

I will look into UITimer.  What I have done for now is in showListener I create a timer.  In the timer event i check if (Display.getInstance().getCurrent() != this) and kill the timer.  That seems to work so far.
