I don't know: is this changed or am I fooled by my memory? I was rather
sure that when the signature of a published event is changed, forms
saved with the old signature cannot be read without error. But now I
notice that this is not true any more.
The version of TAChart which I just committed to trunk had to change the
signature of the TChartDataPointDrawEvent event from
procedure (ASender: TDataPointDrawTool) of object;
to
procedure (ASender: TDataPointDrawTool; ADrawer: IChartDrawer) of object;
Testing this with the demo in folder
(lazarus)/components/tachart/demo/tools in which the event is handled I
was expecting an error - but no, the program compiles and runs fine as
if nothing had changed.
Am I missing something?
