OK,So in the end how can I cast a Interface to a Object in Lazarus?
I usually add a "function getinstance(): <theBaseImplemetationClass>" to
the interface definition.
Which goes completely against the very purpose of interfaces.
If you need this, you should not be using interfaces to begin with.
The only possible excuse is an external requirement to use interfaces.
I do not agree.
No surprise there, I assume you would not have done it otherwise.
It is a free world, after all.
I consider that very wrong design, and this is the reason the OP had to wait
for his answer so long; I tried to provide alternatives for what is in my
personal opinion a unnecessarily complicated and convoluted design.
The fact that no-one else bothered to (or could) reply is IMHO enough of a
hint that the design is maybe not optimal ?
