Thanks, that pretty much works
the only strange behavior is the when I first launch the application
in hosted mode, the event doesn't appear to fire before the widget's
getOffsetHeight is > 0. But as soon as I refresh in hosted mode it
works fine.
And if I compile/browse and trying in IE6/Firefox/Chrome everything
works as expected.
So to ensure it works in hosted mode *every* time I added the
following deferred command to the Widget's constructor, in addition to
onLoad --
DeferredCommand.addCommand(new Command(){
@Override
public void execute() {
if(GWT.isScript()) {
... do calculation ...
}
}
});
I don't really like having to use a hack, but I need it to work in
hosted mode since people are using my widget library and i don't want
them to think something is broken.
Is there a better way than using this deferred command?
