Conditional Display

Conditional display is simply managed with « if » or « switch » and using the generic() method (or the display() method for specific treatments):

public class myPanel extends GPanel {

 GButton but1;
 GButton but2;
 GButton but3;
 GCheckBox cb;

 public myPanel() {
   but1 = new GButton("Bouton 1");
   but2 = new GButton("Bouton 2");
   but3 = new GButton("Bouton 3");
   cb   = new GCheckBox("Display button 3"); 
 }

 public void generic() throws GException {
   put(but1);
   put(but2);
   if ( cb.isSelected() ) { put(but3); } // Easy, isn't it ?
   put(cb);
  }
