I am trying to put buttons with images(gif) on the background which has already been set as an image (shell.setBackgroundImage(image)) and I can't figure out how to remove transparent border around buttons with images. I would be grateful if somebody could give me some tip about this issue.

Here is my code:

import org.eclipse.swt.widgets.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.*;
import org.eclipse.swt.graphics.*;

public class Main_page {
        public static void main(String[] args) {
                Display display = new Display();
                Shell shell = new Shell(display);
                Image image = new Image(display, "bg.gif");
                shell.setBackgroundImage(image);
                shell.setBackgroundMode(SWT.INHERIT_DEFAULT);
                shell.setFullScreen(true);

                Button button = new Button(shell, SWT.PUSH);
                button.setImage(new Image(display, "button.gif"));

                RowLayout Layout = new RowLayout();
                shell.setLayout(Layout);

                shell.open();
                while (!shell.isDisposed()) {
                        if (!display.readAndDispatch())
                            display.sleep();      
                }
                display.dispose();
        }
}

Sorceror, thanks for your answer I will definitely look into this article. Maybe I will find my way. So far I have improved my code a little bit. Firstly, I managed to get rid of the gray background noise. Secondly, I finally succeeded in creating the button as I had seen it in the first place. Yet, another obstacle has arisen. When I removed image(button) transparent border it turned out that the button change its mode(from push button to check box). The problem is that I came so close to the thing I was looking for and now I am a little puzzled. If you have some time please give a glance at my code.

Here is the code, if you launch it you will see what the problem is(hope you didn't have problems downloading images):

import org.eclipse.swt.widgets.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.*;
import org.eclipse.swt.graphics.*;

public class Main_page {
        public static void main(String[] args) {
                Display display = new Display();
                Shell shell = new Shell(display);
                Image image = new Image(display, "bg.gif"); // Launch on a screen 1280x1024
                shell.setBackgroundImage(image);
                shell.setBackgroundMode(SWT.TRANSPARENT);
                shell.setFullScreen(true);


                GridLayout gridLayout = new GridLayout();
                gridLayout.marginTop = 200; 
                gridLayout.marginLeft = 20;
                shell.setLayout(gridLayout);



                // If you replace SWT.PUSH with SWT.COLOR_TITLE_INACTIVE_BACKGROUND
                // you will see what I am looking for, despite nasty check box  

                Button button = new Button(shell, SWT.PUSH); 
                button.setImage(new Image(display, "moneyfast.gif"));



                shell.open();
                while (!shell.isDisposed()) {
                        if (!display.readAndDispatch())
                            display.sleep();      
                }
                display.dispose();
        }
