Wait indicator with grayed out JFrame

Question

I'm looking for some Java library/ class which has two functionalities:

1. I wan't to gray out whole JFrame content during long term operation.
2. Show the wait indicator as a layer on this grayed out JFrame.

I try to find some opensource library, but I couldn't.

I don't want to integrate JavaFX.

Do you know maybe of some good libraries which handle the cover behaviour in a nice way.

Answer 1

1. I wan't to gray out whole JFrame content during long term operation.
2. Show the wait indicator as a layer on this grayed out JFrame.

• use JLayer(best of ways) or GlassPane,

• put there JLabel with

  1. animated gif Icon

  2. few Icons invoked from Swing Timer

  3. create an animations (BufferedImage) by using paintComponent repainted from Swing Timer
