解决方案

在Windows上， setForeground 为按钮作为解决方法，向按钮中添加 PaintListener 。在此侦听器的 paintControl 方法中，获取生成的事件的 GC ，并重写<

你可以在你的上绘制任何东西， Button 。

The SWT Button class has a setForeground(Color) method but it seems to have no effect (the method is actually on Button's superclass). The javadoc says that this method is a hint and may be overridden by the platform. My platform is Windows.

• Does this mean that it is not possible to set button foreground color on Windows?
• Does it work on other platforms?
• Is there a workaround?

解决方案

On Windows, setForeground for Buttons has no effects.

As a workaround, add a PaintListener to your Button. On this Listener's paintControl method, get the generated event's GC and, with it, re-write the text of your Button using the color you want.

You can, in fact, draw anything over your Button.
