[FIXED] Corrupted java swing component

Issue

I'm working on a Java Swing project,

I have an issue with some component while running projects vs running the interface here's some screen shoot :

This look when I run only the jFrame

This is when I run A Frame that lead to this

and this when i run the full project

I want to know why this look difference and how to resolve it.

I'm Using netbeans 12.2 with jdk 15.0.2 on a windows 64 bit machine

Solution

Java Swing by default uses native GUI components. The upside of this is that when done correctly, your Java application will have a Windows style on Windows and a Linux on Linux etc. To get a fixed style, you can set the Java Look And Feel to a LAF that is always available, such as the built-in METAL LAF. This page contains much more specifics on Java Look And Feels, how to set them and even how to create your own if you wish.
