I was thinking that certain nodes (e.g., TextField) won’t provide a valid pref size until the window was made visible (and the CSS had been evaluated).
A few times I’ve added code set Window Opacity to zero, do a Window show/hide, then reset Window Opacity to one. Then you should get valid pref sizes. I’m not proud of myself, but it seems to work in practice. :-) jeff On Aug 4, 2014, at 1:03 PM, Richard Bair <[email protected]> wrote: > autosize() on Node may be what you want (sizes it then afterward you can read > values)? > > On Aug 4, 2014, at 10:56 AM, Mike Hearn <[email protected]> wrote: > >> I'd like to find the calculated height of a node in my window controllers >> initialise() method, so I can shrink the height to zero and then animate it >> to the right size later.
