JTable and JScrollPane

H

helmut.teichmann

Hi,

a very small demo to tell you my problem (I use Java 1.6).
I have a JTable with 11 columns in a smaller JScrollPane.
The problem is, that I can't put the column "10" between the columns
"8" and "9" with the mouse. It scrolls to the first column.
What is wrong with the JScrollPane.
It works fine with older versions of Java.

Who can help me?

You're right. That's busted in Java6. Did you find the bug yet? Surely
due to size calculation bug as commenting
//frame.setResizable(false);
and resizing larger than columns then it works fine.

Not fixed in Java6 Update 2.

}

Works for me in Java 5 and fails in java 6 and Java 6 Update 2.
