FR: allow tooltips as baloons too

[mlaggner]

In addition to the classic tooltips, more modern (web like) balloon like tooltips would be nice.

E.g. Visual Studio Code

or DarkLaf tooltips: https://github.com/weisJ/darklaf/wiki/Tooltips

Well, maybe in the (not so near) future...

At the moment, tooltips (and popups) use native borders with nice native drop shadows on nearly all platforms (except on Windows 10).

Not sure whether native balloon like popups/windows are supported/provided by Windows/macOS/Linux.

So it would be necessary to implement them in Java.
This would be no problem for "light weight" tooltips that fit into the main window.
But there are some technical issues for "heavy weight" tooltips, which are partly/fully out of the main window.
(transparent window and font rendering)

If you need some kind of ballon component now, here is some code used in the FlatLaf demo:

FlatLaf/flatlaf-demo/src/main/java/com/formdev/flatlaf/demo/HintManager.java

Line 244 in 6fdc56f

private static class BalloonBorder

Thanks for the response - I already implemented this for a few tooltips/hints in my app, but having this for all popups would be perfect ;)

At the moment adding them is very cumbersome...
