        public HeapManager​(org.eclipse.swt.widgets.Composite parent,
                           int style)
        Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

        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 widget which will be the parent of the new instance (cannot be null)
        style - the style of widget 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
