Use System Look and Feel

[Vorlent]

Have you tried the native UI Look and Feel?

https://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/plaf.html
Here is the code example I'm referring to

public static void main(String[] args) {
    try {
            // Set System L&F
        UIManager.setLookAndFeel(
            UIManager.getSystemLookAndFeelClassName());
    } 
    catch (UnsupportedLookAndFeelException e) {
       // handle exception
    }
    catch (ClassNotFoundException e) {
       // handle exception
    }
    catch (InstantiationException e) {
       // handle exception
    }
    catch (IllegalAccessException e) {
       // handle exception
    }

    new SwingApplication(); //Create and show the GUI.
}

I tried this, and it looks a bit better, but the main components are JFX, so this has not a huge effect. You mainly get native scrollbars and progress bars:

Shameless plug: I recommend using wchargin/laf-optimizer instead of directly setting the system look-and-feel. It's a tiny utility class that sets the system look-and-feel, and then fixes some platform-specific issues (you can just read the code). Applying it to this project is just

diff --git a/src/main/java/App.kt b/src/main/java/App.kt
index 66c99bd..d5a0b35 100644

         }
     }

after copying LAFOptimizer.java into the same directory as App.kt.

Here are some screenshots of the differences between default and laf-optimized look-and-feels.

I tried the platform look and feel (on macOS) but it broke the sizing on certain elements (always seemed to be height related) :/

[wchargin]

I assumed that the sizing was always broken: if the window is not at a specific size, everything is either cropped or isolated. Neither of the following screenshots is cropped:

Is this not known?

PS Please don't feel obligated to actually fix these on my behalf. I enjoyed playing with it for a bit, but as you describe in your background blog post, I do see the whole thing as a bit of a joke and don't actually intend to use it. (No hard feelings, of course! 🙂 )

Hehe no worries @wchargin —but yeah, I'm probably about done with this for now. Someone would probably have to convert it all to JavaFX if it were to be at all serious—and that won't be me :)

I hadn't seen that issue with resizing. I'm guessing it's a platform thing since everything resizes when the window is resized here.

The height issue with the macOS platform L&F was that comments were set to zero height and progress bars were something like 10px.
