java - Changing org.eclipse.swt.widgets background color in Windows

Question

Right now I am trying to change the background color of a org.eclipse.swt.widgets.Button with the following code:

    Button sceneButton = new Button(border, SWT.TOGGLE | SWT.FLAT);  
    sceneButton.setBackground(Color.RED);

This works fine when I run the program in Solaris, but does nothing when I run the code in Windows. Is this possible? If not, is there some kind of workaround that would allow me to change the background color (even if the "color" is an image) while still displaying text in the button? Thanks!

On windows operating systems button.setBackGround doesn't work directly. A small snippet of code can help. Override the paint event of button as shown below:-

-----obj is button name in below snippet------------

obj.addPaintListener(new PaintListener() {
@Override
    public void paintControl(PaintEvent arg0) {
    // TODO Auto-generated method stub
    obj.setBackground(display.getSystemColor(SWT.COLOR_BLACK));
    org.eclipse.swt.graphics.Pattern pattern;
    pattern = new org.eclipse.swt.graphics.Pattern(arg0.gc.getDevice(), 0,0,0,100, arg0.gc.getDevice().getSystemColor(SWT.COLOR_GRAY),230, arg0.gc.getDevice().getSystemColor(SWT.COLOR_BLACK),230);
    arg0.gc.setBackgroundPattern(pattern);
    arg0.gc.fillGradientRectangle(0, 0, obj.getBounds().width, obj.getBounds().height, true);
    }
});
