TSaveDialog.OnTypeChange not working/firing

Original Reporter info from Mantis: MIS5

• Reporter name:

Description:

OnTypeChange simply does not fire. I do not think it has been implemented in the Cocoa widgetset.

Steps to reproduce:

FMySaveDialog.OnTypeChange := MyExportHandlerTypeChange;

procedure TMainForm.MyExportHandlerTypeChange;
begin
  ShowMessage('This never fires');
end;

Additional information:

Chaning filename file extension when the selected filter/format is changed by the user is a rather important feature

i.e. I have a default filename "default.csv" and then "Comma separated values fil (*.csv)" is also the default selected filter/format

I would like to have the file extension changed whenever he user changes the selected filter/format.

(This is how the dialog behaves on Delphi/Windows/VCL - but from forum I can the OnTypeChange events works on Laazarus/Windows)
