Focus problem

[miguel lisboa]

Since

 setNextFocusableComponent(component) 

is deprecated, how can i control the focus on my components?
thanks in advance

Here's a page from the Swing trail in the java tutorial that deals with focus: How to use the Focus Subsystem

Thanks a lot
that really helped

to those with the same problemas i had, here's what i did:
created this class:

 import java.awt.*;
 
class Foco
        extends FocusTraversalPolicy {
 
        TesteVisual visual;
 
        Foco(TesteVisual v) {
            visual = v;
        }
 

        public Component getComponentAfter(Container focusCycleRoot,
                                           Component aComponent) {
            if (aComponent.equals(visual.txtAno)) {
                return visual.txtTurma;
            }
            else if (aComponent.equals(visual.txtTurma)) {
                return visual.txtNomeUtilizador;
            }
            else if (aComponent.equals(visual.txtNomeUtilizador)) {
                return visual.txtPalavraPasse;
            }
            else if (aComponent.equals(visual.txtPalavraPasse)) {
                return visual.txtEpoca;
            }
            else if (aComponent.equals(visual.txtEpoca)) {
                return visual.lstEpocas;
            }
            else if (aComponent.equals(visual.lstEpocas)) {
                return visual.lstTurmas;
            }
            else if (aComponent.equals(visual.lstTurmas)) {
                return visual.cmdCriar;
            }
            else if (aComponent.equals(visual.cmdCriar)) {
                return visual.cmdEliminar;
            }
            else if (aComponent.equals(visual.cmdEliminar)) {
                return visual.cmdActualizar;
            }
            else if (aComponent.equals(visual.cmdActualizar)) {
                return visual.cmdSair;
            }
            else if (aComponent.equals(visual.cmdSair)) {
                return visual.txtAno;
            }
 
            return visual.txtAno;
        }
 
        public Component getComponentBefore(Container focusCycleRoot,
                                            Component aComponent) {
            if (aComponent.equals(visual.txtAno)) {
                return visual.cmdSair;
            }
            else if (aComponent.equals(visual.cmdSair)) {
                return visual.cmdActualizar;
            }
            else if (aComponent.equals(visual.cmdActualizar)) {
                return visual.cmdEliminar;
            }
            else if (aComponent.equals(visual.cmdEliminar)) {
                return visual.cmdCriar;
            }
            else if (aComponent.equals(visual.cmdCriar)) {
                return visual.lstTurmas;
            }
            else if (aComponent.equals(visual.lstTurmas)) {
                return visual.lstEpocas;
            }
            else if (aComponent.equals(visual.lstEpocas)) {
                return visual.txtEpoca;
            }
            else if (aComponent.equals(visual.txtEpoca)) {
                return visual.txtPalavraPasse;
            }
            else if (aComponent.equals(visual.txtPalavraPasse)) {
                return visual.txtNomeUtilizador;
            }
            else if (aComponent.equals(visual.txtNomeUtilizador)) {
                return visual.txtTurma;
            }
            else if (aComponent.equals(visual.txtTurma)) {
                return visual.txtAno;
            }
 
            return visual.txtAno;
        }
 
        public Component getDefaultComponent(Container focusCycleRoot) {
            return visual.txtAno;
        }
 
        public Component getLastComponent(Container focusCycleRoot) {
            return visual.cmdSair;
        }
 
        public Component getFirstComponent(Container focusCycleRoot) {
            return visual.txtAno;
        }
    }
 
 

note the constructor so that i can control the visual components.
in the gui class (TesteVisual) i added this:

    //Construct the frame
    public TesteVisual() {
//...
 
        Foco newPolicy = new Foco(this);
        this.setFocusTraversalPolicy(newPolicy);
    }

And worked perfectly!
