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);
}
