I'm trying to print a text in a tooltip, and in the end, put an icon, however I'm not getting it, I tried doing with html.

The problem is that the image comes "broken", does not appear.

Whatwouldbetherightwaytodothis?

importjava.awt.Dimension;importjavax.swing.JComponent;importjavax.swing.JFrame;importjavax.swing.JPanel;importjavax.swing.JTextField;publicclassToolTipextendsJFrame{privateJTextFieldjTextField=newJTextField();publicToolTip(){add(tela());setSize(300,300);setVisible(true);setDefaultCloseOperation(EXIT_ON_CLOSE);}privateJComponenttela(){JPanelpainel=newJPanel();painel.add(jTextField);jTextField.setPreferredSize(newDimension(150,20));jTextField.setToolTipText("Nome do campo: " + personalizaToolTip());
        return painel;
    }

    private String personalizaToolTip() {
        //JLabel label = new JLabel();
        //label.setIcon(new ImageIcon(getClass().getResource("/imagens/testeIcon.png")));

        String texto = "<html><body> o campo esta desabilitado.. <img src=\"/imagens/testeIcon.png\"/> </body></html>";
        return texto;
    }

    public static void main(String[] args) {
        ToolTip tp = new ToolTip();
    }
}

Your code works, the problem is you add text outside the html tags, this breaks the tooltip parse.

Change as below:

import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class JTooltipImageTest extends JFrame {

    private JTextField jTextField = new JTextField();

    public JTooltipImageTest() {
        add(tela());
        setSize(300, 300);
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }

    private JComponent tela() {
        JPanel painel = new JPanel();
        painel.add(jTextField);
        jTextField.setPreferredSize(new Dimension(150, 20));
        jTextField.setToolTipText(personalizaToolTip("Nome do campo: "));
        return painel;
    }

    private String personalizaToolTip(String text) {


       return "<html><body>" + text + " o campo esta desabilitado.. <img src='" + getClass().getResource("/imagens/testeIcon.png") + "' /></body></html>";
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> JTooltipImageTest tp = new JTooltipImageTest());
    }
}

Notice that I just concatenated your text inside the string, so that it succeeds in the <html> tag, as this should be the first thing in the string for rendering to work correctly.

See a test with an image:
