How to Detect Cancel Event Dialog in "UniFileUploadButton"

[Luciano França]

If I choose a file the event "UniFileUploadButton1Completed"
will be called but if I click the "Cancel" button in the Dialog I don't have an event to capture.

There is no such standard event. I think it's possible only by workarounds. You can google it.

How could I adapt this code in unigui

Or  I believe that a simple way to solve
How can I wait for a call to return?

Example

 UniFileUploadButton1.JSInterface.JSCall('fileInputEl.dom.click', []);

 While DialogOpen do  //  How to check if Dialog is open ?
  UniSession.Synchronize;

 if Not Assigned(AStream) Then
  Showmessage('Botão cancel');
