Hi all,
in the following program I expect the JRadioButtons
be placed on the left edge. But they start at the center.
What should be done to "move" them to the left? Thanks.

Add this - it will explain
radioPanel.setBorder(new EtchedBorder());

Positioning is also function of your Layout, not just the radio
buttons themselves. Read up on details of BoxLayout positioning. If
it won't give you the control you need, ramp up to a more complex
layout.
