Both the this.setCaption(x) and the generic setter this.set({caption:
x}) should work. You should first find out why you get an error (maybe
you post the error message here, for instance). May be related to your
sub-classing.
Since you are "trying to _dynamically_ change the caption of a window",
i.e. programmatically and _not_ in combination with an user interaction
(button click, etc.), you may have to flush the queues manually to
update the UI:
qx.ui.core.Widget.flushGlobalQueues();
Since most changes to the UI are related to user interaction, you
normally would not have to trigger such an update manually. You
frequently need to do so explicitly, though, for AJAX calls that result
in immediate changes to the UI.
Hope that helps,
Andreas
