如果选中另一个，我该如何取消选中radiobutton？

Question

I am using a content pane with gridbag layout and i have created 3 JRadioButtons . I have an actionlistener that makes a command when they are press and in a different method I handle the actions.

I tried buttonname.setSelected(false); and it does not work. I searched about this and people were talking about button groups so I created one and added the buttons to the group like this:

    ButtonGroup group = new ButtonGroup();
    group.add(color1);
    group.add(color2);
    group.add(color3);

I put that in my pane thing where I add components to pane after I added the buttons with pane.add(buttonname, c);

How do I group.clearSelection() or whatever the command is from my action handling method?

Answer 1

This is from the Javadocs of ButtonGroup

This class is used to create a multiple-exclusion scope for a set of buttons. Creating a set of buttons with the same ButtonGroup object means that turning "on" one of those buttons turns off all other buttons in the group. A ButtonGroup can be used with any set of objects that inherit from AbstractButton.

So it would seem that you do not need to do anything.
