Of course since DialogService.MessageDialog is a procedure. I guess because on mobile platforms this is non-modal dialog.

class procedure MessageDialog(const AMessage: string; const ADialogType: TMsgDlgType;
  const AButtons: TMsgDlgButtons; const ADefaultButton: TMsgDlgBtn; const AHelpCtx: THelpContext;
  const ACloseDialogProc: TInputCloseDialogProc); overload;

I am afraid there is no way to provide a function for ACloseDialogProc. But you can use the procedure to show a simple message, with say an OK button (customizable version of ShowMessage).

@lmbelo Can we do some special wrapping of this and related functions?

got it need Wrap TPyDelphiDialogServiceSync = class(TPyDelphiObject) private function GetDelphiObject: TDialogServiceSync; procedure SetDelphiObject(const Value: TDialogServiceSync); public class function DelphiObjectClass: TClass; override; public property DelphiObject: TDialogServiceSync read GetDelphiObject write SetDelphiObject; xx=DialogServiceSync.MessageDialog('hello2', 'mtInformation', ['mbYes', 'mbNo'], 'mbYes', 0 ) print(xx) ruslt a integer thanks
