Cinq méthodes de disposition communes pour le swing à Java

1. Disposition de la bordure

2. Flowlayout

3. Disposition de la grille

4. Boxlayout

5. Disposition vide (null)

Il y a aussi deux autres dispositions, à savoir Gridbaglayout et Cardlayout

Remarque: JFrame et JDialog sont des dispositions car BorderLayout, Jpanel et Applet sont des dispositions sous le nom de FlowLayout

Exemple de code de mise en page de la limite:

 import java.awt.borderlayout; import javax.swing.jbutton; importer javax.swing.jframe; classe publique borderlayoutexample étend jframe {jbutton btn1 = new JButton ("East"); JBUTTON BTN2 = New Jbutton ("Sud"); JBUTTON BTN3 = New Jbutton ("Western"); JBUTTON BTN4 = New Jbutton ("North"); JBUTTON BTN5 = New Jbutton ("Medium"); BorderLayOnexample () {init (); this.setTitle ("BorderLayout"); this.setResiSable (true); this.setSize (200, 200); this.setLocationRelativeto (null); this.setDefaultCloseOperation (exit_on_close); this.setVisible (true); } void init () {this.setLayout (new BorderLayout (10,5)); // par défaut est 0, 0; Espacement horizontal 10, espacement vertical 5 this.add (btn1, borderlayout.East); this.add (btn2, borderlayout.south); this.add (btn3, borderlayout.west); this.add (btn4, borderlayout.north); this.add (btn5, borderlayout.center); } public static void main (String args []) {new BorderLayOnexample (); }}
