örnek olarak 0 'dan, bu da windowsta mouse wheel ile scroll edilmiyor. nedir acaba sorun,

	    shell = new Shell();

	    shell.setSize(450, 300);

	    shell.setText("SWT Application");

	    shell.setLayout(new FormLayout());


	    Composite composite = new Composite(shell, SWT.NONE);

	    composite.setBackground(SWTResourceManager.getColor(SWT.COLOR_YELLOW));

	    FormData fd_composite = new FormData();

	    fd_composite.bottom = new FormAttachment(0, 46);

	    fd_composite.right = new FormAttachment(100);

	    fd_composite.top = new FormAttachment(0);

	    fd_composite.left = new FormAttachment(0);

	    composite.setLayoutData(fd_composite);

	    composite.setLayout(new FillLayout(SWT.HORIZONTAL));


	    Composite composite_1 = new Composite(shell, SWT.NONE);

	    FormData fd_composite_1 = new FormData();

	    fd_composite_1.right = new FormAttachment(0, 100);

	    fd_composite_1.top = new FormAttachment(composite, 1);

	    fd_composite_1.left = new FormAttachment(0);

	    fd_composite_1.bottom = new FormAttachment(100);

	    composite_1.setLayoutData(fd_composite_1);


	    Composite composite_2 = new Composite(shell, SWT.NONE);

	    composite_2.setLayout(new FillLayout(SWT.HORIZONTAL));

	    FormData fd_composite_2 = new FormData();

	    fd_composite_2.top = new FormAttachment(composite, 1);

	    fd_composite_2.left = new FormAttachment(composite_1, 1);

	    fd_composite_2.bottom = new FormAttachment(100);

	    fd_composite_2.right = new FormAttachment(100);

	    composite_2.setLayoutData(fd_composite_2);


	    ScrolledComposite scrolledComposite = new ScrolledComposite(composite_2, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);

	    scrolledComposite.setBackground(SWTResourceManager.getColor(SWT.COLOR_DARK_RED));

	    scrolledComposite.setExpandHorizontal(true);

	    scrolledComposite.setExpandVertical(true);


	    Composite composite_3 = new Composite(scrolledComposite, SWT.NONE);

	    composite_3.setLayout(new GridLayout(1, false));


	    Composite composite_4 = new Composite(composite_3, SWT.NONE);

	    composite_4.setBackground(SWTResourceManager.getColor(SWT.COLOR_BLUE));


	    Composite composite_5 = new Composite(composite_3, SWT.NONE);

	    composite_5.setBackground(SWTResourceManager.getColor(SWT.COLOR_MAGENTA));


	    Composite composite_7 = new Composite(composite_3, SWT.NONE);

	    composite_7.setBackground(SWTResourceManager.getColor(SWT.COLOR_DARK_BLUE));


	    Composite composite_6 = new Composite(composite_3, SWT.NONE);

	    scrolledComposite.setContent(composite_3);

	    scrolledComposite.setMinSize(composite_3.computeSize(SWT.DEFAULT, SWT.DEFAULT));
