Deselect Radio Buttons

Hi!

I made a Unit Converter Program, but theres one problem...

When I run it everything works, but when i press the button clear (look in the screenshot) the text field gets cleared, but the buttons stay the same.

so what i am asking, is how whould make it so when I press clear both the text field, and the buttons get "cleared"

here's the Code for the GUI:

Code:

have you try setSelected method?

I suggest that you add the two columns of jradiobuttons into two ButtonGroups. Then when you want to clear the selection call clearSelection() on both button groups.

No, I have not tried that , thanks

how would i use setSelected()?

i agree with Fubarable
use two buttonGroup (ButtonGroup (Java Platform SE 6))

use add method of buttonGroup to add buttons
use clearSelection method to clear selection

Or if you want a class that's easier to use than ButtonGroup, you can try my Select Button Group on tips4java.
