SWT- 如何在 Windows 中更改 ProgressBar 颜色? [英] SWT- How to change ProgressBar color in Windows?

问题描述

有没有办法在 SWT 中更改 ProgressBar 条的颜色?.setForeground() 似乎不起作用.

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

如果无法以编程方式更改颜色，是否可以使用 WindowBuilder GUI 工具更改 ProgressBar 的颜色?

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?

谢谢！

推荐答案

在 SWT 中，有 3 种内置状态，每种状态用一种颜色表示:

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. 

此状态不支持不确定的进度条样式(SWT.INDETERMINATE).

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

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

此状态将暂停不确定的进度条动画.

This state will pause the indeterminate progress bar animation.

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