[Guest]

nur eine Zeile einfügen hat bei mir geklappt:

   /** 
    * This method initializes jMenuItem    
    *     
    * @return javax.swing.JMenuItem    
    */ 
   private JMenuItem getJMenuItem() { 
      if (jMenuItem == null) { 
         jMenuItem = new JMenuItem(); 
         jMenuItem.setText("Login"); 
         jMenuItem.addActionListener(new java.awt.event.ActionListener() { 
            public void actionPerformed(java.awt.event.ActionEvent e) { 
               jPanel1.setVisible(false); 
               jPanel2.setVisible(true);
               jTextField.requestFocus(true); //Die hier ist neu
            } 
         }); 
      } 
      return jMenuItem; 
   }

achja, und ein :

	public static void main(String args[]) {
		(new testFocus()).setVisible(true);
	}

🙂

[Guest]

Bin ich auch überfragt, ich hätte auf :

private void test(){ 	   
    DlgTestFocus  dlg = new DlgTestFocus(f);
    dlg.setTitle("Scanner suchen"); 
    dlg.setModal(true); 
    dlg.setVisible(true); 
    dlg.getTextfield().requestFocus(true);

// oder auf:	   
//    final testFocus f=this;
//    SwingUtilities.invokeLater(new Runnable(){
//        public void run(){
//            DlgTestFocus  dlg = new DlgTestFocus(f);
//            dlg.setTitle("Scanner suchen"); 
//            dlg.setModal(true); 
//            dlg.setVisible(true); 
//            dlg.getTextfield().requestFocus(true);
//        }
//    });
}

getippt, geht aber beides nicht :-/ Kann aber nicht lang dauern, bei dem KSKB wird sich sicher bald noch jemand anders die Mühe machen 🙂
