Browse Button

[celloman]

Hallo Leute

Habe ein Browse Button erstellt, ich möchte gerne durch ein klick auf den Button das Browse Fenster öffnen (JFilechooser).

public class converter extends javax.swing.JFrame {
    
    /** Creates new form converter */
    public converter() {
        initComponents();
    }
    
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
     */

Erzeugst hast Du das Objekt bereits, Du musst es nur mehr anzeigen.

        jButton4.setText("Browse...");
        jButton4.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                int option = jFileChooser1.showOpenDialog(this);
                File file = jFileChooser1.getSelectedFile();
                if (option == JFileChooser.APPROVE_OPTION && file != null) {
                   ...
                }

            }
        });

Also um es mal kurz zu sagen: Wir sind nicht dazu da, deine Hausaufgaben zu machen.
Wir helfen natürlich gern weiter, aber irgendwie hab ich nicht den Eindruck, dass du schon selbst was ausprobiert hast. Falls doch: was hat daran nicht funktioniert? JFileChooser ist eigentlich nicht so kompliziert, dass man den nicht versteht, wenn man mal in die API reinschaut...
