Hi
I want to prevent my GUI application from displaying the exception
(and stopping execution) when a problem occurs and rather log the
message to syslog.

I thought about reassigning OnShowException to my own procedure to
handle this but I can't find much documentation on OnShowException. Am
I on the right track or is there a better way to solve this problem?
Are there any thing I should be aware of when doing this?

Assign your own event handler to the Application instance.

Application.OnException := @MyExceptionHandler;
...
procedure TMyForn.MyExceptionHandler(Sender : TObject; E : Exception);
begin
  LogToFile(E.ClassName, E.Message, ...);
end;
