FormLayout

[Guest]

Hallo zusammen,

ich hab ein Problem mit meinem FormLayout in meinem E-mail Client.
Und zwar will ich, dass die TextFields das fenster komplett in der Breite füllen (das funktioniert ja auch). Jedoch soll das AttatchmentPanel umbrechen, wenn die Anhänge in der breit nichtmehr drauf passen(deshalb das FlowLayout an der stelle)

Wie kann ich das schaffen???

Danke im voraus!

package newClient.gui;

import java.awt.Dimension;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextArea;
import javax.swing.JTextField;

import com.jgoodies.forms.builder.PanelBuilder;
import com.jgoodies.forms.layout.CellConstraints;
import com.jgoodies.forms.layout.FormLayout;

public class NewMail extends JFrame {

	public NewMail(){
		this.setTitle("Neue E-Mail");
		this.layoutComponents();
		this.setPreferredSize(new Dimension(800,600));
		this.pack();
		this.setLocationRelativeTo(null);
		this.setVisible(true);
	}
	
	private void layoutComponents(){
		PanelBuilder builder = new PanelBuilder(new FormLayout("2dlu,p,4dlu,fill:p:grow,2dlu","2dlu,p,4dlu,p,4dlu,p,4dlu,p,6dlu,fill:p:grow,2dlu"));
		
		CellConstraints contraints = new CellConstraints();
		
		builder.add(new JButton("Mail senden"), contraints.xy(2, 2));
		builder.add(new JLabel("Empfänger:"), contraints.xy(2, 4));
		builder.add(new JLabel("Betreff:"), contraints.xy(2, 6));
		builder.add(new JLabel("Anhänge:"), contraints.xy(2, 8));
		
		builder.add(new JTextField(), contraints.xy(4, 4));
		builder.add(new JTextField(), contraints.xy(4, 6));
		builder.add(new AttatchmentPanel(false), contraints.xy(4,8));
		
		builder.add(new JTextArea(), contraints.xyw(2, 10, 3));
		this.getContentPane().add(builder.getPanel());
	}
}

Hab' zwar das FormLayout nicht, aber du kannst mal schauen, ob das mit dem Umbruch funktioniert, wenn du das "FlowLayout mit Zeilenumbruch" ausprobierst, das Hobbit_Im_Blutrausch mal irgendwann in den Codeschnipseln gepostet hatte.
