Answer 1

I would perhaps look at using JXLayer for this. It looks like what you're trying to do here is paint some context outside the of component's bounds. This is the kind of thing JXLayer excels at.

Answer 2

This can be a little bit tricky. When you need semitransparent border it will be pain. If not, it is easy. Just use popup with appropriate components and mouse listener to listen on mouse events occurred over active borders.

java - Getting boundary information from a 3d array

Hey, I'm currently trying to extract information from a 3d array, where each entry represents a coordinate in order to draw something out of it. The problem is that the array is ridiculously large (and there are several of them) meaning I can't actually draw all of it. What I'm trying to accomplish then, is just to draw a representation of the outside coordinates, a shell of the array if you'd like. This array is n...

For example, rounding monetary values half-up to nearest cent. Testing 0.005 rounds up to 0.01 is easy. Testing <0.005 rounds down is not (strictly speaking). I can obviously test an arbitrary value like 0.0049, but this doesn't guarantee that another value like ...
