How make the HContainer navigable?
Hello, I am trying to make my own 揅omponent? I want put some buttons pictures (HStaticIcon) to HContainer. I wont add first HStaticIcon using HContainer.add(HComponent) and next by using HContainer.addAfter(HComponent). And now there is my problem I don抰 know what interface I have to implements to my HContainer to make him focusable and navigable. I think I have to implements 揌State,HNavigable,HFocusListener,HNavigationInputPreferred?but I don抰 know how. I don抰 know what I have to do in inherited methods like:
public void setMove(int keyCode, HNavigable target) {
}
public HNavigable getMove(int keyCode) {
return null;
}
public void setFocusTraversal(HNavigable up, HNavigable down, HNavigable left, HNavigable right) {
addHFocusListener(this);
this.up = up;
this.down = down;
this.left = left;
this.right = right;
}
Is here anybody who can help me? Thanks you very much for your help. My functionless code is here:
public class PersonAgeMenu extends HContainer implements HState,HNavigable,HFocusListener,HNavigationInputPreferred{
private HStaticIcon v6_12;
