Hello,

Okay.

You can use UniURLFrame1.OnFrameLoaded event.

Onloadedform imediately hide the mask , 

Form1.showmask;

Try

Do_print_frame();

Finally

Form1.hidemask();

End;

Sory uniurlframe onframeloaded, i mean, the hidemask imediate run before the procedure do_print_frame() 

[donlego]

 

 

procedure TFrmPostBayar.UniURLFrame1FrameLoaded(Sender: TObject);
begin
  inherited;
 if UniURLFrame1.URL<>'' then
 begin
  FrmPostBayar.ShowMask('');
  try

     // long proses to preview
        UniURLFrame1.JSInterface.JSCode
    ('Ext.defer(function(){'#1'.iframe.contentWindow.print()}, 10);');
  finally
  FrmPostBayar.HideMask;

  end;

 end;
end;
