Hi,
I need to change the color of a SWT CLabel from dark blue to light blue.

Can you please tell me how I can fade from dark blue to a lighter blue in this CLabel?

This is the code I have that make it dark blue color:

        GridData gridDataBanner = new GridData(SWT.FILL, SWT.FILL, true, false);

        
        CLabel banner = new CLabel(shell, SWT.CENTER);
        Color MWBlue = new Color (shell.getDisplay(), 62, 87, 189);
        banner.setBackground(MWBlue); 
        
        FontData fontData = banner.getFont().getFontData()[0];
        Font fontBanner = new Font(shell.getDisplay(), new FontData(fontData.getName(), 10, SWT.BOLD));
        banner.setFont(fontBanner);
        banner.setForeground(shell.getDisplay().getSystemColor(SWT.COLOR_WHITE));
        

        banner.setText("\nSOMETHING \n ");
        banner.setLayoutData(gridDataBanner);

Replace lines 5 & 6 with this...
banner.setBackground(new Color[] { display.getSystemColor(SWT.COLOR_DARK_BLUE), display.getSystemColor(SWT.COLOR_BLUE) }, new int[] { 100 });

Obviously, you can use different colors, etc if you want. You can also do a bit more complex gradients with this method, if you desire. The javadoc alludes to some things you can do, but it might not be obvious as to what it's doing, so if you want more info, just ask!

Use this instead then...
banner.setBackground(new Color[] { display.getSystemColor(SWT.COLOR_DARK_BLUE), display.getSystemColor(SWT.COLOR_BLUE) }, new int[] { 100 }, true);
