Wie verwende ich ein Vorlagen-Dialogfeld für mehrere Schaltflächen?

Question

Ich schreibe eine GUI in Java. Ich habe eine JXTable, in der ich derzeit nur statische Daten habe, aber ich möchte, dass der Benutzer Daten mithilfe eines von mir erstellten Vorlagenfelds eingeben kann.

    Object[][] data = {

     buttonPane.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5)); 

     diagTemplate.add(buttonPane, BorderLayout.PAGE_END); 
     diagTemplate.add(rowContent, BorderLayout.CENTER); 

     add(diagTemplate); 
    } 

    public void closeWindow(){ 
     Window win = SwingUtilities.getWindowAncestor(this); 
     if(win != null) { 
      win.dispose(); 
     } 
    } 
} 

Wie Sie beiden Tasten im Fenster sehen könnten erstellt den Dialog, der zum ersten Mal erstellt wird („Zeile hinzufügen“ oder „Edit Row“). Ich möchte, dass sie verschiedene Dialoge erstellen, so dass die Bearbeitung von Daten nicht mit dem Hinzufügen von Daten in Konflikt steht.

Vielen Dank im Voraus.

Answer 1

ein anderes Dialog-Erzeugungsverfahren jede Taste zuweisen, so dass Sie zwei Dialoge öffnen:

public void openRowPane(String name){ 
     if(dialog == null){ 
      Window win = SwingUtilities.getWindowAncestor(this); 
      //change modality 
      dialog = new JDialog(win, name, ModalityType.MODELESS); 
      dialog.getContentPane().add(diagPanel); 
      dialog.pack(); 
      dialog.setLocationRelativeTo(null); 
     } 
     dialog.setVisible(true); 
    } 

    public void openRowPane2(String name){ 
     if(dialog2 == null){ 
      Window win = SwingUtilities.getWindowAncestor(this); 
      //change modality  
      dialog2 = new JDialog(win, name, ModalityType.MODELESS); 
      dialog2.getContentPane().add(diagPanel2); 
      dialog2.pack(); 
      dialog2.setLocationRelativeTo(null); 

     } 
     dialog2.setVisible(true); 
    }
