Text Field disabling in NetBeans
提问by 3yoon af
I want to ask if there is a way to make the text field active and inactive according to the radio button.
我想问一下是否有办法根据单选按钮使文本字段处于活动状态和非活动状态。
For example, the textfield will be inactive and when the user click on the radio button, the textfield will be active.
例如，文本字段将处于非活动状态，而当用户单击单选按钮时，文本字段将处于活动状态。

You could have two radio buttons for representing the active/inactive state. Add an action listener to each and when the 'active' one is pressed you call setEditable(true) on the JTextField and when the 'inactive' JRadioButton is called you call setEditable(false).
您可以有两个单选按钮来表示活动/非活动状态。为每个添加一个动作侦听器，当按下“活动”时，您在 JTextField 上调用 setEditable(true)，当调用“非活动”JRadioButton 时，您调用 setEditable(false)。
JTextField textField = new JTextField();
JRadioButton activeButton = new JRadioButton("Active");
JRadioButton inactiveButton = new JRadioButton("Inactive");
activeButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
textField.setEditable(true);
}
});
inactiveButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
textField.setEditable(false);
}
});
