2 つのJlabelの名前を変更するトグル ボタンを取得しようとしてtoggledいuntoggledますActionListener。
ボタンを押すと、toggled Jlabelが表示され、 untoggled Jlabelが非表示になります。エラーは発生していませんが、トグルを解除すると、選択した状態またはトグル状態と同じままです。
JToggleButtonコードは次のとおりです。
JToggleButton tglbtnNewToggleButton = new JToggleButton("New toggle button");
tglbtnNewToggleButton.setBounds(351, 387, 121, 23);
tglbtnNewToggleButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent actionEvent) {
AbstractButton abstractButton = (AbstractButton) actionEvent.getSource();
boolean selected = abstractButton.getModel().isSelected();
if (selected =true) {
untoggled.setVisible(false);
toggled.setVisible(true);
}
else{
toggled.setVisible(false);
untoggled.setVisible(true);
}
}
});
