Guidelines for Writing Delphi Components
Over the years, I have used components written by several companies.
There are a number of problems that seem to be repeated - this lists a few
the are easy to avoid.
I discuss general coding guide lines in
- this page covers additional guidelines that apply specifically to components.
Many of the Bolrand components have private methods.
This effectively prevents deriving a new component to fix design errors.
Because of license restrictions, you can not simply fix the broken code
and distribute the fixes ...
but if all functions are virtual and non-private
then it is possible to distribute fixes.
I suggest that NO methods should ever be made private
and that all methods should be virtual.
