我正在尝试将一些组件添加到JPanelin flowLayout。 

JPanel panelPrincipal = new JPanel();
principale.getContentPane().add(panelPrincipal, BorderLayout.CENTER);
panelPrincipal.setLayout(new BorderLayout(0, 0));

JPanel panelDynamique = new JPanel();
JScrollPane jScrollPane = new JScrollPane(panelDynamique);
panelPrincipal.add(jScrollPane, BorderLayout.CENTER);

if(this.getNbAppFor(champs.get(6)) > 0) {
    JLabel lblMAJ = new JLabel(champs.get(6));
    panelDynamique.add(lblMAJ);
    panelDynamique.add(new JSeparator());

    JPanel panelMAJ = new JPanel();
    panelMAJ.setLayout(new GridLayout(this.getNbAppFor(champs.get(6))/2, 2));
    panelDynamique.add(panelMAJ);
}

if(this.getNbAppFor(champs.get(7)) > 0) {
    JLabel lblDispo = new JLabel(champs.get(7));
    panelDynamique.add(new JSeparator());

    JPanel panelDispo = new JPanel();
    panelDispo.setLayout(new GridLayout(this.getNbAppFor(champs.get(7))/2, 2));
    panelDynamique.add(panelDispo);
}

这是核心构建，但看起来不像我预期的那样。

我对我正在尝试做的事情做了一个说明：

预期结果

如何将组件添加到FlowLayout前一个组件下的下一个“行”中？我怎样才能让我的分隔符填满我的宽度Container？

根据您的图纸，但没有使用FlowLayout。

package testp;

import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JSeparator;

public class LayTest {

    public static void main(String[] args) {

        JPanel p = new JPanel();
        p.setLayout(new GridBagLayout());

        GridBagConstraints c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 0;
        c.anchor = GridBagConstraints.WEST;
        c.weightx = 1;
        p.add(new JLabel("Mide a jour"), c);

        c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 1;
        c.fill = GridBagConstraints.HORIZONTAL;
        p.add(new JSeparator(), c);

        c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 2;
        c.weighty = 1;
        c.fill = GridBagConstraints.HORIZONTAL;
        p.add(new JPanel(), c);

        c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 3;
        c.fill = GridBagConstraints.HORIZONTAL;
        p.add(new JSeparator(), c);

        c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 4;
        c.anchor = GridBagConstraints.WEST;
        p.add(new JLabel("Disponsible"), c);

        c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 5;
        c.fill = GridBagConstraints.HORIZONTAL;
        p.add(new JSeparator(), c);

        c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 6;
        c.weighty = 1;
        p.add(new JPanel(), c);


        JFrame f = new JFrame();
        f.setSize(300, 400);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(p);
        f.setVisible(true);

    }

}
