Im building a GUI in Netbeans, it looks good in the designer but when I run the program it looks pretty rubbish. Im using a Mac and so I feel that it would look better using the Mac OS LAF but then when I run it on Windows, what will happen? Is a Windows system able to use the Mac LAF and vice-versa?
I dont usually mind the Ocean/Metal LAF but it looks better on Windows than it does on Mac, is there a way to set a theme as a fallback? Or to change depending on the system its running on?
The UIManager.setLookAndFeel(String className) Loads the LookAndFeel specified by the given class name:className, using the current thread's context class loader.
To set look and feel of your current system, make use of UIManager.getSystemLookAndFeelClassName(): Returns the name of the LookAndFeel class that implements the native system look and feel if there is one, otherwise the name of the default cross platform LookAndFeel class.
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
put this code before you create instance of your application window: JFrame or any such Top-level Container.

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
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.
I have a swing application, that has its look and feel set to the custom L&F from the company at the main method, where the application is started.
The problem is: This works for ALL frames and windows, but somehow it doesn't work for JDialogs.
I've even manually set the L&F during the initialization of the dialog, but still get the platform dependent L&F.
Looking for answers or bugs that might explain this behavior, I found this thread, that explains that the environment variables change the behavior of the UIManager, so I've set the variables swing.crossplatformlaf and swing.systemlaf to return my custom L&F, but still get the OS dependent L&F.
Is there something that I'm missing here? How can Swing configure a different L&F for just JDialogs? I'm having a different L&F on Linux and Windows because of this.
Any help would be appreciated.
I made a simple Jframe with its child components in netbeans, when i run the application it shows it in NIMBUZZ lookandfeel as shown below:-
But I want it to be always shown in WINDOWS lookandfeel as shown below :-
How am I suppose to do that??
Before creating your first window call this code:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
note that this will work as expected only under windows where this is the system LAF
You maybe looking for setWindowDecorationStyle(), although some L&Fs may not support the feature. A complete example is cited here.
In my Java application I have a window which holds a JTextArea within a JScrollPane with scrollbars policies set to AS_NEEDED.
As I run my application I see that JTextArea this way:
Why am I seeing the scrollbars with that cutaway knob (which doesn't reflect a "standard" representation like this)?
The Layout for the frame is GridBagLayout, and I'm on Mac OS X 10.8.2, should that matter.
This is based on the Look and Feel your app is using, and the limitations of Java's integration with the native OS layout components. The one in your screenshot looks like Nimbus.
Swing applications always custom-render the look and feel, and don't do a very good job of using the native OS widgets everywhere. The result is that you get weird looks that might be consistent the OS only some of the time, or only with certain layout components.
Welcome to developing cross-platform desktop apps in Java. :(
To attempt to get the system look and feel when your application starts you can do this:
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassname());
} catch (Exception e) {
// Handle exception
}
This will set the look and feel to that of the system regardless of what you run it on.
And as mentioned, the default look and feel for your application appears to be Nimbus and not OSX's Aqua, which again can be fixed with he above snippet and you could (should you care to) offer a UI option to the user to change the look and feel of the application to whatever they chose.
You are with Nimbus LookAndFeel

Is there a way (using Java) to make the GUIs that you create look like normal Windows programs? I don't like the look and feel of the Java buttons and scrollers and stuff... It can use those if it's running on Mac or Linux, but I'd like it to inherit the buttons and stuff from Windows. Any suggestions?
You can set the look and feel of any Swing program to the native operating system's with one call.
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName())
The Windows PLAF can be seen in the Nested Layout Example.
