set根据动作命令在按钮组中选择一个特定的jradiobutton [英] setSelected a specific jradiobutton in a buttongroup based on action command

问题描述

我想根据actionCommand（/特定jradiobutton的名称）setSelected在按钮组中指定一个jradiobutton。

i want to setSelected a speicfic jradiobutton in a buttongroup based on the actionCommand(/name of the specific jradiobutton).

可以通过ind.setSelected（true ）

it could be done usind .setSelected(true)

，例如

JRadioButton rabbitButton = new JRadioButton("rabbit");
 rabbitButton .setActionCommand("rabbit");
JRadioButton pigButton = new JRadioButton("pig");
 pigButton .setActionCommand("pig");

ButtonGroup group = new ButtonGroup();

group.add(rabbitButton);
group.add(pigButton);

现在..没有，

{ RabbitButton.setSelected（true）;} NOR {group.setSelected（rabbitButton.getModel，true）}

{ rabbitButton.setSelected(true);} NOR {group.setSelected(rabbitButton.getModel,true)}

是否可以根据操作设置setSelected（true）rabbitButton command（）？

is there a way to setSelected(true) rabbitButton based on the action command()?

推荐答案

yourButtonGroup.clearSelection();
yourRadioButton.setSelected(true);
