I am facing an issue with my Java Swing project in NetBeans on macOS, specifically related to the background color of components. I have a JButton in my GUI, and I'm trying to set their background colors from the properties. However, despite setting the color values in the code, the background colors do not appear as expected when I run the program.
Here is a snippet of the relevant code from the initComponents method:
// Code from initComponents method
jButton1.setBackground(new java.awt.Color(102, 255, 51)); // Light green color
jButton1.setOpaque(true);
jLabel1.setBackground(new java.awt.Color(255, 51, 0)); // Bright red color
set the setOpaque(true) property. Reinstalled NetBeans. Tried with a panel and without it. Despite these efforts, the background colors are not updating as expected. Are there any known issues with Java Swing in NetBeans on macOS, especially on M1 chips? Any suggestions on how to troubleshoot and resolve this issue would be greatly appreciated.
Here is the entire code:
