How do I remove "tab borders" in JTabbedPane

Question

I would like to remove the lines drawn around just the "tab" at the top. So I am on left with the label text.

How can I do this? I HAVE SEARCHED extensively but nothing works for me.

Answer 1

Below are all the UIManager values that seem to affect the area you are targeting. As my previous answer didn't work for you I have listed all the ones I believe are relevant, I would suggest copying the below list and then commenting various ones out to monitoring the effects and see if one, or a combination will prove successful for you. I recommend putting them in before calling the tabbedpane constructor.

    UIManager.put("TabbedPane.borderHightlightColor", java.awt.Color.CYAN); 
    UIManager.put("TabbedPane.darkShadow", java.awt.Color.CYAN); 
    UIManager.put("TabbedPane.light", java.awt.Color.CYAN);
    UIManager.put("TabbedPane.selectHighlight", java.awt.Color.CYAN);
    UIManager.put("TabbedPane.darkShadow", java.awt.Color.CYAN);
    UIManager.put("TabbedPane.focus", java.awt.Color.CYAN);

I have put the color CYAN because it is very bright, and so very clear what has changed with each one.

Good luck!

You're searching for:

UIManager.getDefaults().put("TabbedPane.lightHighlight", Color.BLACK);
UIManager.getDefaults().put("TabbedPane.selectHighlight", Color.BLACK);
