Live layout of Swing windows

Thread view:

I have seen Swing applications where they do what I call "live layout" and I
want to know how to do it in my application. Live layout is where the
contents of a frame/window are laid-out continuously while the user resizes
the window by moving the resize border with the mouse. This happens *while*
they have the mouse button pressed. This is opposite to the way most Swing
applications (including mine) work where the laying out of contents is only
performed *after* the user releases the mouse button and not while the
actual window is being resized.

I am sure it must be something simple or even complex, it doesn't matter.
Most Windows programs work in this way and I want my Swing applications to
work in the same manner.

Does anyone know the method used to accommodate live layout? Please don't
send me to a URL or ask me to RTFM; I've done the layout tutorial already
and now I just need some help.

Thanks,

Wes

The technical term for this is "dynamic layout".

Well, in spite of your admonition I send you to this URL
http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Toolkit.html#setDynamicLayout(b
oolean)
and request you to read it. ;-)
Looks like
Toolkit.getDefaultToolkit().setDynamicLayout(true);
is exactly what you want.

Yes, that's it exactly! I thought it would be something simple. Thanks
very much.
