Java Tutorial/SWT/CTabItem

Adding CTabItems

Because no styles apply, pass SWT.NONE for the style. Optionally, you can pass an index to specify the zero-based order of the tab. The constructors are as follows:

   <source lang="java">

public CTabItem(CTabFolder parent, int style) public CTabItem(CTabFolder parent, int style, int index)</source>
