Hi everybody,

The manual (possibly Delphi one) says that TThread.OnTerminate executes in the GUI thread. This is easy if the GUI thread owns the TThread.

Suppose the GUI owns a TTHread which owns a subthread. In which context does the subthread's OnTerminate execute?

Thanks

Under unix OnTerminate is always called in the main thread:

procedure TThread.CallOnTerminate;
begin
  // no need to check if FOnTerminate  nil, because
  // thats already done in DoTerminate
  FOnTerminate(self);
end;
procedure TThread.DoTerminate;
begin
  if Assigned(FOnTerminate) then
    Synchronize(@CallOnTerminate);
end;

Always the main thread; no matter in which thread a thread was started.

There simply is no information about which thread has started another particular thread.

Michael.

Thanks Mattias and Michael
