How to set SWT button foreground color?

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.

This is the code to Implement FOreground Color in Buttons in SWT with allowing Mnemonic key to be Shown also and Enabled by Pressing Alt+"Mnemonic Key";

Button radioButton=new Button(parent,SWT.RADIO);
StringBuffer sb = new StringBuffer("I am a Coloured radio button");
String name=null;
 String S = "I am a Coloured radio button";
String substr="C";
int i=S.indexOf(substr);
sb.insert(i,"&");
S=sb.toString();
name=sb.substring(i, i+2);
name=sb.toString();
String whiteSpace=" ";
final String TName=S;

for(int l=0;l<1000;l++)
    whiteSpace=whiteSpace.concat("            ");

radioButton.setText(name+whiteSpace);

radioButton.addPaintListener(new PaintListener(){
 String name=TName;
    @Override
    public void paintControl(PaintEvent e) {
        // TODO Auto-generated method stub
        e.gc.setForeground(hex2Col("ffffcc"));
        int x=21;
        int y=21;
        e.gc.drawText(name, x,y,SWT.DRAW_MNEMONIC | SWT.TRANSPARENT);

    }

});

Note: hex2Col is my own method to Convert hex Color Code to Color Type

Note: Here ALT+C is Mnemonic Key Combination i have Used

If you need Button with style SWT.CHECK you can try use Button without text and add Label element. Example:

chkAutorun = new Button(fCompositeLogin, SWT.CHECK);
Label lblAutorun = new Label(fCompositeLogin, SWT.NONE);
lblAutorun.setForeground(white);
lblAutorun.setText("Autorun");

On windows, setForeground doesn't work for Group either.

If you can convince your users to use the Classic Theme, setForeground will miraculously work.

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.
