[Bug 1894419] Re: Wrong TextPane.background color with GTKLookAndFeel on dark theme
Hi, here is the reproducer;
OpenJDK version/OS version:
openjdk 11.0.8 2020-07-14 / Mint Linux 20
openjdk 1.8.0_265 / Ubuntu 20.04
import java.awt.*;
import javax.swing.*;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.StyleSheet;
public class Example {
private String toHex(Color color) {
return String.format("#%02x%02x%02x", color.getRed(), color.getGreen(),
color.getBlue());
}
public Example() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException |
IllegalAccessException | UnsupportedLookAndFeelException e) {
e.printStackTrace();
}
JFrame frame = new JFrame();
JTextPane pane = new JTextPane();
pane.setContentType("text/html");
((HTMLDocument) pane.getDocument()).setPreservesUnknownTags(false);
String text = "Displays the text using htmlDocument class "
+ "font color : TextPane.foreground=" +
toHex(UIManager.getColor("TextPane.foreground"))
+ " background color : TextPane.background=" +
toHex(UIManager.getColor("TextPane.background"))
+ " background color should lighter when light mode
and darker when dark mode.";
StyleSheet styleSheet = ((HTMLDocument)
pane.getDocument()).getStyleSheet();
styleSheet.addRule("body { font-family: Arial; font-size: 24pt;
font-style: bold;"
+ " color: " + toHex(UIManager.getColor("TextPane.foreground"))
+ "; "
+ " background: " +
toHex(UIManager.getColor("TextPane.background")) + "; "
+ " }");
pane.setText(text);
pane.setPreferredSize(new Dimension(800, 200));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(pane, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {

[Bug 1894419] Re: Wrong TextPane.background color with GTKLookAndFeel on dark theme
Forgot to add what happened in my case.
- background was dark
- text was white
I modified the code a bit to simplify it:
import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JTextPane;
public class Example {
public Example() {
JFrame frame = new JFrame();
JTextPane pane = new JTextPane();;
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pane.setPreferredSize(new Dimension(200, 200));
frame.getContentPane().add(pane, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
new Example();
}
}
** Changed in: openjdk-lts (Ubuntu)
Status: New => Incomplete

Thank you for taking the time to report this bug and helping to make Ubuntu better. I tried the code in https://stackoverflow.com/a/31928409 with Ayu- Mirage-Dark and I couldn't reproduce the issue. Please provide the following items: - a reproducer with actual code - the exact OpenJDK version - which Ubuntu release was this tested on I'm setting it as incomplete for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894419 Title: Wrong TextPane.background color with GTKLookAndFeel on dark theme To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-lts/+bug/1894419/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
