OLE Automation Sample
SUMMARY
=======
The SPoly sample draws polygons. The only way to make SPoly draw a polygon
is to use its programmability interface.
One OLE automation object is exposed by Spoly: spoly.application.
The object spoly.application is associated with SPoly's main application
window. It controls drawing polygons and clearing the display.
MORE INFORMATION
================
SPoly implements IDispatch for spoly.application.
Methods defined on spoly.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 the line width of the polygon.
SetWidth(width as short) Set the line width of the polygon.
Shortcomings of this sample
---------------------------
Many items in this sample should be properties. Instead, they are
implemented as methods. Anything that behaves like an attribute of the
object should be a property.
This is not a good example of how to implement a collection.
