find "real" height/width swing/awt object

because canvas3d doesn't have ability resize boldly progenitor frame, i means lane user resizes window following resize manually myself. (if ends adult crashing canvas3d, docs suggest, i simply destroy reconstruct user resizes window). biased way involves being means accurately tell large enclosing quarrel start with.

the twin methods i've tried:

panel.getheight();
panel.getpreferredsize().height;

don't seem accurately news things: getheight() constantly zero, getpreferredsize() advantage numbers don't indeed have anything tangible distance panel.

any ideas?

edit: so, i took debugger quarrel vigilant manually legalised non-object properties i didn't anything resembled width/height. granted, there sub-objects i didn't feeling at. also, maybe window manifest (it isn't, during indicate i'm interfacing object) i query height/object?

edit 2: so, representation classes subclasses awt classes, i suspect you're means height/width those, proceed generalize. i've nice due accordingly.
