Description Tomas Pavek 2003-03-25 16:58:00 UTC 
[release35 build 200303242350, jdk 1.4.x]

GridBagLayout has problems with large JTextFields
having weightx set to 0. When the container is too
small, all component sizes in the container are
screwed. If the GridBag customizer is invoked in
such moment, it hangs with 100% CPU (it tries to
display the components, but they have enormous
width, the computation takes forever). The IDE
must be killed from console...

Workaround is to set right layout constraints
(i.e. weightx to 1).

To reproduce, see attached form. Open it and
shrink the designer - the JTextField dissappears
(the same happens if you execute the form, it's
GridBagLayout behavior). Then invoke the GridBag
customizer.

Tomas, I'm removing the RELNOTE keyword since this bug has 
been fixed. Let me know if there  is info I should include 
in the readme anyway.
Comment 5 Tomas Pavek 2003-04-02 14:54:06 UTC 
This has been fixed in trunk only, not in NetBeans 3.5 - so that's why
the RELNOTE keyword. There could me some text like the following in
readme:

GridBag customizer in form editor may occasionally hang if the layout
contains JTextArea with long text that needs to be wrapped and its
Weight X layout property is set to 0. Workaround is to set Weight X to
1 for text components first.
Comment 6 Patrick Keegan 2003-04-02 15:03:27 UTC 
OK. I just added it. Thanks.
Comment 7 Jaromir Uhrik 2003-04-17 16:20:12 UTC 
Verified in dev build #200304170100. I see no problems or 
side effects.
Comment 8 Jan Chalupa 2003-04-18 11:30:00 UTC 
This is a potential showstopper. QA would like the fix to be
backported into release35.
