        public CTreeComboColumn​(CTreeCombo parent,
                                int style)
        Constructs a new instance of this class given its parent (which must be a Tree) and a style value describing its behavior and appearance. The item is added to the end of the items maintained by its parent.

        The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

        Parameters:
        parent - a composite control which will be the parent of the new instance (cannot be null)
        style - the style of control to construct
        Throws:
        java.lang.IllegalArgumentException -
        • ERROR_NULL_ARGUMENT - if the parent is null
        org.eclipse.swt.SWTException -
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
        • ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

      • CTreeComboColumn

        public CTreeComboColumn​(CTreeCombo parent,
                                int style,
                                int index)
        Constructs a new instance of this class given its parent (which must be a Tree), a style value describing its behavior and appearance, and the index at which to place it in the items maintained by its parent.

        The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

        Note that due to a restriction on some platforms, the first column is always left aligned.

        Parameters:
        parent - a composite control which will be the parent of the new instance (cannot be null)
        style - the style of control to construct
        index - the zero-relative index to store the receiver in its parent
        Throws:
        java.lang.IllegalArgumentException -
        • ERROR_NULL_ARGUMENT - if the parent is null
        • ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the parent (inclusive)
        org.eclipse.swt.SWTException -
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
        • ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass
