How do I change the background color of jtabbedpane?
•
Java
I know you can modify the LAF properties, but if you don't, how can you do it? I'm just asking, because setbackground doesn't seem to do that
Please note that I am looking to change the following properties:
> TabbedPane. Background (or tabbedpane. Contentareacolor?) > TabbedPane. tabAreaBackground
Solution
Taking tabcomponentsdemo as an example, setbackgroundat() seems to be valid:
private void initTabComponent(int i) { pane.setTabComponentAt(i,new ButtonTabComponent(pane)); pane.setBackgroundAt(i,Color.getHSBColor((float)i/tabNumber,1,1)); }
Appendix: as @ camickr does, the target component must be opaque
import java.awt.Color; import java.awt.Dimension; import java.awt.EventQueue; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTabbedPane; /** @see https://stackoverflow.com/questions/8752037 */ public class TabColors extends JPanel { private static final int MAX = 5; private final JTabbedPane pane = new JTabbedPane(); public TabColors() { for (int i = 0; i < MAX; i++) { Color color = Color.getHSBColor((float) i / MAX,1); pane.add("Tab " + String.valueOf(i),new TabContent(i,color)); pane.setBackgroundAt(i,color); } this.add(pane); } private static class TabContent extends JPanel { private TabContent(int i,Color color) { setOpaque(true); setBackground(color); add(new JLabel("Tab content " + String.valueOf(i))); } @Override public Dimension getPreferredSize() { return new Dimension(320,240); } } private void display() { JFrame f = new JFrame("TabColors"); f.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE); f.add(this); f.pack(); f.setLocationRelativeTo(null); f.setVisible(true); } public static void main(String[] args) { EventQueue.invokelater(new Runnable() { @Override public void run() { new TabColors().display(); } }); } }
