I've noticed that a simple call to JEditorPane.setBackground(Color) doesn't work in Nimbus. setBackground() seems to work for JTextAreas fine, but not JEditorPane. Why is this? The only workaround I can come up with is to install a BasicEditorPaneUI on my JEditorPane, which will honor the setBackground() call, but then I have to workaround other issues (such as setting the selected text and selection colors to match the rest of Nimbus).
Below is an SSCCE. Any ideas? Is there an easier solution than changing the UI?
import java.awt.*;
import javax.swing.*;
import javax.swing.text.JTextComponent;
public class NimbusTest extends JFrame {
final Color BACKGROUND = new Color(232,232,255);
public NimbusTest() {
JPanel contentPane = new JPanel(new BorderLayout());
JTextComponent editor = createEditorPane();
contentPane.add(new JScrollPane(editor));
setContentPane(contentPane);
setTitle("Nimbus Test");
setSize(350, 350);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private JTextComponent createEditorPane() {
//JTextArea editor = new JTextArea();
JEditorPane editor = new JEditorPane();
// Comment this out and JEditorPane BG won't be changed for Nimbus
if (UIManager.getLookAndFeel().getName().equals("Nimbus")) {
Color selFG = editor.getSelectedTextColor();
Color selBG = editor.getSelectionColor();
editor.setUI(new javax.swing.plaf.basic.BasicEditorPaneUI());
editor.setSelectedTextColor(selFG);
editor.setSelectionColor(selBG);
//editor.setContentType("text/html");
}
editor.setBackground(BACKGROUND);
editor.setText("This is some sample text");
return editor;
}
/**
* Program entry point.
*
* @param args Command line arguments.
*/
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
//UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
} catch (Exception e) {
e.printStackTrace();
}
new NimbusTest().setVisible(true);
}
});
}
}
