Under Swing1.0.3, the code below exhibited fairly nice behavior for
JTable column header resize in a JScrollpane. In Swing1.1beta3, the
behavior is different/unexpected/unacceptable. Happens under jdk1.1.7a
w/swing1.1beta3 jar (or jdk1.2RC2 w/plugin), Win95, IE 4.01 w/SP1.
Perhaps with all the JTable resizing updates, I've missed something
new that I should be doing to avoid this behavior.
Steps to reproduce:
1) Scroll the JTable in "Test" JIF all the way to the right (so that at least
Column A is not in view).
2) Pull the column header divider between cols D & E to the left. Problem:
Columns C, B etc. scoot over to the right as column D's size is reduced.
Under Swing1.0.3, columns C,B etc. did not scoot over to the right as
column D's size was reduced. You have to compile/run the code under
both releases to see what I talking about. Results in Column D's size
being reduced too quickly (unexpected).
Perhaps this is by design through new implementation of the options
I'm using below.
