Public Member Functions

virtual void Restore (RenderRegion *, BOOL)
virtual void Render (RenderRegion *, BOOL Temp=FALSE)
virtual void SimpleCopy (AttributeValue *)
virtual NodeAttribute * MakeNode ()
 Makes the appropriate NodeAttribute-derivative from an end-arrow attribute.
BOOL IsDifferent (AttributeValue *pAttr)
 Compare two AttributeValue objects. The base class version always returns TRUE - derived classes should override this function to provide functionality.

Static Public Member Functions

static BOOL Init ()
 Registers line width attribute, and provides a default attribute to give non-dotted lines.

BOOL EndArrowAttribute::IsDifferent (  AttributeValue *  pAttr  )  [virtual]
 

Compare two AttributeValue objects. The base class version always returns TRUE - derived classes should override this function to provide functionality.

Author:
Tim_Browse (Xara Group Ltd) <camelotdev@xara.com>
Date:
12/04/94
Parameters:
pAttr - the attribute to compare against this one. [INPUTS]
Returns:
TRUE if objects represent different attributes (e.g. one is red and the other is blue); FALSE otherwise (i.e. they represent the same attribute, e.g. both represent 0.25pt lines).
