fxruby users - Jan 2009 - No more GUI update after FXRuby app put in the background?

Hi,

Here is a small program that represents the GUI I use for deploying
FXRuby applications: a small window, with a progress bar in it.

It works fine, as long as the application is not put in the background.
Then the GUI stops being updated, even if the application is put back to
the foreground again.

Is there anything I can do for this?

Thanks,

Philippe Lang

Hi again,

I found the solution, I hope it can help someone: the trick is to call
"$app.runWhileEvents" now and then, to give a chance to fox to process
OS events... I should have remembered that before... !
