Thanks for your answer!
The laser pointer part is a program running on a pc, maybe I shouldn't have used the
word application in the same context as smartphone, sorry.
So the whole setup right now is as follows:
- A bluetooth client app running on an Android smartphone, which converts gestures to a series of coordinates sent to...
- a bluetooth "server" program running on a Windows 10 laptop (where the JavaFX stuff takes place at the moment)
I have two more specific questions regarding my problem:
1.) Is there a way to make a fullscreen exclusive mode application with for example an undecorated Swing JFrame transparent for mouse events?
2.) Is it maybe a better idea to have a tiny undecorated transparent window just big enough to display the laser pointer dot and move that whole window (instead of moving the dot inside a transparent fullscreen window) ?
Thanks again,
Joe
