Is there a way to put a JSlider into the macOS menu bar? I'm using Swing with Kotlin to make a Tetris clone, and I want to use JSliders in the menu bar to control some settings (in this case, how rounded the edges of the board's tiles are, and the size of the gap between them).

The problem is that when I try to do so, neither the JSliders nor their JLabels show up. Is there...

Creating singletons using Initializer<T> vs object Heyo, I'm looking for some advice.

But, looking at the sample code, where they construct an ExampleLogger with a dependency on...

But this only works for float and not List. fun giveMeSomeFloats(@FloatRange(from = 0.0, to = 1.0) floats: List) Here, someone can actually pass in...
