I have algready googled about the subject, but found nothing regarding user Usability.
SwingX can be put on table instead of Swing. Third party components in either side can too, as long as they aren't so many that most GUI is based on them.
Using a few components of a framework inside another one isn't desireble.
What I'm rly looking for is which one provides best productivity and complex graphical components, that resambles Windows native Look&Feel.
For example. I've not worked with Swing for some years, but I remember that masks over edit input didn't work well in Swing. While Borland VLC components used to process mask as soon as user typed a key, Swing used to wait for the component to lose focus to process mask as "fix" the
string.
