[news.eclipse.platform.swt] Re: Checkbox trees and disabled nodes

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi Alex,

Unfortunately a color constant for this does not currently exist, the
request for it is https://bugs.eclipse.org/bugs/show_bug.cgi?id=22782 .

The only way I can think of determining this is to add a PaintItem listener
to a disabled Table/Tree and seeing what the foreground colour of its GC is,
as shown in the snippet below:

public static void main (String [] args) {
    Display display = new Display ();
    final Shell shell = new Shell (display);
    shell.setLayout(new FillLayout());
    Tree tree = new Tree(shell, SWT.NONE);
    //tree.setEnabled(false);
    new TreeItem(tree, SWT.NONE).setText("item");
    tree.addListener(SWT.PaintItem, new Listener() {
        public void handleEvent(Event event) {
            System.out.println(event.gc.getForeground().getRGB());
        }
    });
    shell.open();
    while (!shell.isDisposed ()) {
            if (!display.readAndDispatch ()) display.sleep ();
    }
    display.dispose ();
}

HTH,
Grant
