Création d'un ChekboxGroup avec java Fermé

Question

Bonjour,
quel est le code java permettant d'écrire la liste des choix dans un ChekboxGroup et d'afficher ce dernier sur mon interface?Aidez moi s'il vous plait.
Merci

Salut,

Pourquoi pas qqch du genre

		ButtonGroup bg = new ButtonGroup();
		bg.add(getConnectionAdminRB());
		bg.add(getConnectionHistRB());
		bg.add(getConnectionNormRB());


où les méthodes get retournent des JRadioButton? Ceci marche également pour des JCheckBox à la place des boutons radio (mais moins courant de les utiliser dans une interface si des choix à faire sont mutuellement exclusifs).

HTH,

Les 3 méthodes get retournent un JRadioButton (ou une JCheckBox, si tu y tiens) ==> remplacer avec tes propres radio boutons ou checkbox.

Une autre question stp,comment je peux ecrire ma liste de choix et l'afficher dans le CheckBox? ==> là je ne comprends pas trop, est-ce que tu parles d'une ComboBox??

En tout cas, voici un petit exemple montrant l'utilisation des boutons radio, des checkboxes et d'une JComboBox, j'espère que cela sera plus clair:

package minos11.test;

import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;

import javax.swing.ButtonGroup;
import javax.swing.DefaultComboBoxModel;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;

public class MinosSample extends JFrame {
	private static final long serialVersionUID = 1L;
	private JComboBox comboBox;

	/**
	 * Launch the application
	 * 
	 * @param args
	 */
	public static void main(String args[]) {
		try {
			MinosSample frame = new MinosSample();
			frame.setVisible(true);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	/**
	 * Create the frame
	 */
	public MinosSample() {
		super();
		setBounds(100, 100, 500, 375);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		final JPanel centerPane = new JPanel();
		final GridBagLayout gridBagLayout = new GridBagLayout();
		gridBagLayout.rowHeights = new int[] { 0, 7, 7 };
		centerPane.setLayout(gridBagLayout);
		getContentPane().add(centerPane);

		final JRadioButton radioButton = new JRadioButton();
		radioButton.setText("New JRadioButton");
		final GridBagConstraints gridBagConstraints_4 = new GridBagConstraints();

		final GridBagConstraints gridBagConstraints_6 = new GridBagConstraints();
		gridBagConstraints_6.fill = GridBagConstraints.HORIZONTAL;
		gridBagConstraints_6.anchor = GridBagConstraints.WEST;
		centerPane.add(radioButton_2, gridBagConstraints_6);

		final JCheckBox checkBox = new JCheckBox();
		checkBox.setText("New JCheckBox");
		final GridBagConstraints gridBagConstraints = new GridBagConstraints();

		gridBagConstraints_1.fill = GridBagConstraints.HORIZONTAL;
		gridBagConstraints_1.anchor = GridBagConstraints.WEST;
		gridBagConstraints_1.gridy = 1;
		gridBagConstraints_1.gridx = 1;
		centerPane.add(checkBox_1, gridBagConstraints_1);

		final JCheckBox checkBox_2 = new JCheckBox();
		checkBox_2.setText("New JCheckBox");
		final GridBagConstraints gridBagConstraints_2 = new GridBagConstraints();
		gridBagConstraints_2.fill = GridBagConstraints.HORIZONTAL;
		gridBagConstraints_2.anchor = GridBagConstraints.WEST;
		gridBagConstraints_2.gridy = 1;
		gridBagConstraints_2.gridx = 2;
		centerPane.add(checkBox_2, gridBagConstraints_2);

		comboBox = new JComboBox();
		final GridBagConstraints gridBagConstraints_3 = new GridBagConstraints();
		gridBagConstraints_3.fill = GridBagConstraints.HORIZONTAL;
		gridBagConstraints_3.anchor = GridBagConstraints.WEST;
		gridBagConstraints_3.gridy = 2;
		gridBagConstraints_3.gridx = 0;
		centerPane.add(comboBox, gridBagConstraints_3);

		final JPanel southPane = new JPanel();
		final FlowLayout flowLayout = new FlowLayout();
		flowLayout.setAlignment(FlowLayout.RIGHT);
		southPane.setLayout(flowLayout);
		getContentPane().add(southPane, BorderLayout.SOUTH);

		final JButton okButton = new JButton();
		okButton.setText("OK");
		southPane.add(okButton);

		// On rajoute les 3 radio buttons au 1er group, les trois checkboxes ou 2ème group et on remplit le combo
		ButtonGroup bg1 = new ButtonGroup();
		ButtonGroup bg2 = new ButtonGroup();
		bg1.add(radioButton);
		bg1.add(radioButton_1);
		bg1.add(radioButton_2);

		bg2.add(checkBox);
		bg2.add(checkBox_1);
		bg2.add(checkBox_2);

		DefaultComboBoxModel model = new DefaultComboBoxModel();
		model.addElement("1er élément");
		model.addElement("2ème élément");
		model.addElement("3ème élément");
		comboBox.setModel(model);

	}
}
