How to add radio buttons in button group?

Question

在Netbeans 7.2中拖放按钮组之后，如何在该按钮组中添加单选按钮？

Answer 1

There's a Button Group field in the radio button's property. Set this value for each of the radio button that you want to add in the group to the button group's name.

Answer 2

1. Drag a ButtonGroup from the palette and drop it on your GUI. It will show up under Other Components in the Inspector panel.
2. Right-click on it and Change variable name to something meaningful.
3. Now select a radio button in your GUI.
4. In the Properties panel look for the buttonGroup property.
5. Click the combo box next to it and select your button group.

Answer 3

Click on the Button Group and then click anywhere in the design form. Select all the buttons you want to group by pressing CTRL and the button. Right click on one of the buttons and select properties. In the ButtonGroup of the Properties, click on the down arrow. Your selection of button groups should appear. Left click on the one you want.

Answer 4

In Netbeans 8.0.1, I use:

ButtonGroup bG = new ButtonGroup();
    bG.add(btn_1);
    bG.add(btn_2);
    bG.add(btn_3);
    bG.add(btn_4);
    ....
