Hi!
I have a component, and a tool in Delphi.
I wanna call it from Python.
I can implement all things I need into a Delphi generated DLL.
It is ok, I can use this DLL from Python, but the DLL procedure needs a
callback procedure to return the partially output, and needs a python
passed variable to check terminate/abort signal.
For example:
procedure ProcessFiles(In putFiles : string; CallBackProc:
??????????????? ?????????); export;
begin
....
CallBackProc(Pr ocessedFiles, Percentage, NeedToAbort);
if NeedToAbort then Exit;
....
end;
def CallBackProc(Pr ocessedFiles, Percentage, NeedToAbort):
...
But I don't know, how to call back this procedure, and how to pass
variables.
The other way is a ActiveX.
This time I don't load the DLL, I only construct the Delphi based Com
Object, and I start the process.
But in this way I also don't know how to implement the callback, because
the main code uses callback events, and I need to use too...
Thanks for every usable help!
