Hey allemaal,

Ik heb een probleem... en dat probleem is namelijk dit:

Ik heb hier drie klassen
- 1ste klas die roept een JFrame op en
- de 2e class zorgt voor onderandere buttons enzo. en hier gaat het fout... op één of andere manier blijft ie steken op een bepaalde grootte... als ik em zet naar bijv. 800x600 dan... blijft ie gewoon bij zijn vorige grootte.
- De derde class is de class voor 't oproepen van een gif voor de splash.

Ik heb em ook geprobeerd de grootte te veranderen in de 1ste class zelf.. maar dat wil ook niet..

hieronder zijn de codes:

code:

import javax.swing.UIManager;
import java.awt.*;

public class SplashApp {
      boolean packFrame = false;
    
      public SplashApp() {
            FrameMain frame = new FrameMain();\
            Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
            int x = (int)(screenSize.getWidth() - 500) / 2;
            int y = (int)(screenSize.getHeight() - 400) / 2;
            frame.setLocation(x, y);
            frame.pack();
            frame.show();
      }
      public static void main(String[] args) {
            try {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
            }
            catch(Exception e) {
            e.printStackTrace();
            }
            SplashApp slashApp = new SplashApp();
      }
}

code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class FrameMain extends JFrame {
      JPanel contentPane;
      BorderLayout borderLayout1 = new BorderLayout();
      JTextArea jTextArea1 = new JTextArea();
      JLabel jLabel1 = new JLabel();
      JLabel jLabel2 = new JLabel();
      JButton jButton1 = new JButton();
      JRadioButton jRadioButton1 = new JRadioButton();
      FrameSplash frmSplash;
    
      public FrameMain(){
            try{
            frmSplash = new FrameSplash(this, 5000, "splash.gif");
            frmSplash = null;
            jbInit();
            pack();
            }
            catch(Exception ex){
            JOptionPane.showMessageDialog(this, ex, "Exception", JOptionPane.ERROR_MESSAGE);
            }
      }
    
      private void jbInit() throws Exception  {
            contentPane = (JPanel) this.getContentPane();
            jTextArea1.setText("jTextArea1");
            contentPane.setLayout(borderLayout1);
            this.setSize(new Dimension(400, 300));
            this.setTitle("Main Frame");
            jLabel1.setText("jLabel1");
            jLabel2.setText("jLabel2");
            jButton1.setText("jButton1");
            jRadioButton1.setText("jRadioButton1");
            contentPane.add(jTextArea1, BorderLayout.CENTER);
            contentPane.add(jLabel1, BorderLayout.NORTH);
            contentPane.add(jLabel2, BorderLayout.SOUTH);
            contentPane.add(jButton1, BorderLayout.WEST);
            contentPane.add(jRadioButton1, BorderLayout.EAST);
      }
    
      protected void processWindowEvent(WindowEvent e) {
            super.processWindowEvent(e);
            if (e.getID() == WindowEvent.WINDOW_CLOSING) {
