Hi,
after attempting this snippet of code provided by Carlos, it seems that java-linux
allows resizing
of this Dialog despite the setResizable( false ) call, while java in winNT doesn't do
so.
I tried it with jdk116v5 and netscape 4.5 on linux and netscape 4.5, MSIE4.01, sun
jdk1.1.6 and
microsoft sdk3.1 on Windoze
I thing that this looks like a bug.
I tried chainging the layout to grid layout and flow layout as well, but the virtual
machine seems
to refractory to manage ;-}.
Dimitris.
