After executing the method I'm getting "Control '' has no parent
window' at the CopyRect line. I'm sure there is another method to copy a
TCanvas to a TFPCustomCanvas.
Use Chart.PaintOnCanvas instead. See savedemo for an example.
Note that you must give it full TCanvas -- just TFPCanvas is not enough.
Yes, but, how can I use a TCanvas in a CGI app?
If I write:
Chart.PaintOnCanvas(TCanvas(lCanvas), Rect(0, 0, 100, 100));
I get an Access Violation.
Simply said: you can't.
The current TAChart is not suitable for a CGI application. It expects a GUI.
