SWT CTabFolder doesn't display when running from eclipse

Question

I am creating an app using WindowBuilder in eclipse 4.4.2. I've added CTabFolders and corresponding CTabItems. The tabs are displayed properly when Click the preview button(Quickly test/preview the window without compiling or running it) in windowbuilder.

But the real problem is when I run the app,the tabs are not displayed.

Can anyone suggest a solution. Thanks in advance.

Answer 1

And Finally I've figured the problem in the code. The composite in the base layout was assigned with the StackLayout as follows.

Composite content = new Composite(shell, SWT.BORDER);    
content.setLayout(new StackLayout());    
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

When I changed the StackLayout to GridLayout, I got a working solution.

    Composite content = new Composite(shell, SWT.BORDER);       
    content.setLayout(new GridLayout(1, false));
    content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
