Hello,Is there any way to define the appropriate type for `AMethod` (in mode ObjFPC)? TTestClass = Class Public Class Procedure AMethod; End; I tried Type TSomeType = Class Procedure; But this didn't work. Rather obvious of course since this could also be interpreted as a class named `Procedure` [I think]. Also I tried Type TSomeType = Class Procedure of Object; But this didn't get me any further. I read the manual (section 3.6 -- http://www.freepascal.org/docs-html/ref/refse17.html) and it contains no data in respect to this little problem of mine.
There is no real solution for this.
Any ideas? BTW: For time being I fixed it through TProcType(Pointer(@TTestClass.AMethod)), where `TProcType = Procedure;`. I think this boiles down to the same as a class procedure is nothing more than a normal procedure as I see it (except for the name and some other syntax)
This is not correct. A class method without static still has a hidden parameter through which the class type is passed. If you want to use the above you need to declare your method as "static;". In that case a method will behave the same as a normal procedure variable, but if you want to change e.g. class properties or class variables of the class the method belongs to, you must use the class name (e.g. TMyClass.MyProperty) to access it.
