Hi.
I'm usually at icedtea web maillist, but this bug seems to be 100%
swing-related.
I'm trying to display a dialog, centered on screen, which size is
fitted to changing contents.
AFAIK, this should be done using pack().
Running the "attached testcase", I have noticed two things:
- After each pack, as the BorderLayoutseem to be center-resized, the
window moves down after each click (but pack always seem to work).
IMHO this is not a friendly behaviour, but can be solved adding a
setLocationRelativeToafter pack
- If I add a setLocationRelativeTo(as shown below) pack fails from
time to time and incorrectly sizes the dialog.
Can you guys help me?
