JRadioButton positioning in JRE 1.4

Thread view:

I've long been maintaining an application that positions many JRadioButtons
inside JFrames having GridLayouts. For an application built with SDK 1.3, the
positioning of the buttons has always been consistent with JRE 1.2 and 1.3.
However I've found that the same application executed under JRE 1.4 results in
the buttons being positioned more to the right in the JFrame. The problem is
that the allocation of space is such that right side labels, which are always
1-3 digits, no longer fit when the label is 3 digits. There are good reasons
why I don't want to stretch my graphics horizontally so is there something I can
do to get the same Look 'n Feel from JRE 1.4 that JRE 1.2 and 1.3 gave me?

You can override the default borders for all instances
of JRadioButton and JCheckBox. Or you can use a l&f
that does this automatically to ensure a consistent
appearance over the different platforms.

The open source Plastic l&f family and the JGoodies
Windows l&f remove the borders as described above.

The project is located at http://looks.dev.java.net/

Hope this helps,

I can think of three parameters that constitute what you call "borders." They
are the insets of the JRadioButton, the insets of the frame, and the horizontal
and vertical gaps in the GridLayout that positions the button in the frame.
Since the application sets these parameters (they are 4's, 2's, and 0's
respectively) and since those values don't change whether the application is
being executed by JRE 1.3 or 1.4, what exactly do you think I should override?
If the JRE is taking these parameters and rendering things differently then I
don't understand what I should override or how the custom L & F packages you
mentioned will help.
