Set JLabel in Tab of JTabbedPane (JAVA)

Question

I am trying to put a JLabel in tab of JTabbedPane but it isn't showing... here is the code that i am using:

...
public class FormulariosTabbedPane extends JTabbedPane implements IEventoListener<TipoDeEvento> {

...
    @Override
    public void eventoDisparado(EventoGenerado<TipoDeEvento> eventoGenerado) {
        ...

        addTab(null, pnlCrearEditarProceso);

        JLabel labelPest = new JLabel("Crear proceso");
        labelPest.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 5));
        labelPest.setForeground(Color.WHITE);

        setTabComponentAt(indexOfComponent(pnlCrearEditarProceso), labelPest);
        setTabComponentAt(indexOfComponent(pnlCrearEditarProceso), new ButtonTabPanel(this));
        setSelectedIndex(indexOfComponent(pnlCrearEditarProceso));

        ...
    }
...

}

And here the result:

What can be wrong?... thanks in advance

Answer 1

This can be caused because of this:

setTabComponentAt(indexOfComponent(pnlCrearEditarProceso),labelPest);
setTabComponentAt(indexOfComponent(pnlCrearEditarProceso),new ButtonTabPanel(this));

This won't merge the labelPest and ButtonTabPanel together, this firstly use labelPest, but then ButtonTabPanel overwrites labelPest.

Your ButtonTabPanel should contain a Label, then this will work. Without the source code of this class I cant help you in general.
