SWT- How to change ProgressBar color in Windows?

问题:

Is there a way to change the color of a ProgressBar's bars in SWT? .setForeground() doesn't seem to work.

If there is not a way to change the color programmatically, is there a way to change ProgressBar's color using the WindowBuilder GUI tools?

Thanks!

In SWT there are 3 built-in states, each represented by a color:

progressBar.setState(SWT.ERROR); //Red Fill color. Useful when the task is aborted. 

This state does not support an indeterminate progress bar style (SWT.INDETERMINATE).

progressBar.setState(SWT.PAUSED); //Yellow Fill color.

This state will pause the indeterminate progress bar animation.

progressBar.setState(SWT.NORMAL); //Default state and color as controlled by OS.

You can't change the color of the progress bar on Windows using SWT.

You can now, using JProgressBar.setForeground( Color )
