How can you make a ComboBox expand and show it’s optons, programatically?
Perhaps you can try something like this:
final ComboBox[] combos = new ComboBox[10]
;
Property.ValueChangeListener listener = new Property.ValueChangeListener() {
public void valueChange(ValueChangeEvent event) {
StringBuffer sb = new StringBuffer();
for (int i = 0; i < 10; i++) {
sb.append(i > 0 ? "-" : "");
sb.append(combos[i]
.toString());
}
mainWindow.showNotification("State = " + sb);
}
};
for (int i = 0; i < 10; i++) {
combos[i]
= new ComboBox("Box " + i);
combos[i]
.addListener(listener);
mainWindow.addComponent(combos[i]
);
}
