OLE Automation Sample Program: SPoly2
-------------------------------------
SPoly2 is a program which draws polygons. The only way to
make spoly2 draw a polygon is to use its programmability
interface.
One OLE Automation object is exposed by spoly2:
* spoly2.application
Spoly2.Application is the object associated with spoly2's main
window. It controls drawing polygons and clearing the display.
-----------------
Program Structure
-----------------
SPoly2 implements IDispatch by using INTERFACEDATA, DispGetIDsOfNames
and DispInvoke.
------------------------------------
Methods defined on spoly2.application
------------------------------------
Name Description
------------------------------------------------------------------
Draw() Draw the polygon.
Reset() Delete all points from the polygon.
AddPoint(X, Y) Add a point with coordinates (x,y)
to the polygon
EnumPoints() as VT_ENUM Return a collection of the polygon's
points
GetXOrigin() as short Get the X origin of the polygon.
SetXOrigin(x as short) Set the X origin of the polygon.
GetYOrigin() as short Get the Y origin of the polygon.
SetYOrigin(y as short) Set the Y origin of the polygon.
GetWidth() as short Get and the line width of the polygon.
SetWidth(width as short) Set the line width of the polygon.
---------------------------
Shortcomings of this sample
---------------------------
1. Many items in this sample should be properties. Instead,
they are implemented as methods. Anything which behaves like
an attribute of the object should be a property.
2. This is not a good example of how to implement a collection.
