title: Access local user file on Qt for Web Assembly
body: <p>I want to access to local files (read binary file) in my software on Qt for Web assembly.</p>
  
  <p>It seems there is already a function to do that: QFileDialog::getOpenFileContent. But I can't find any related example to show how to use this function. I'll appreciate that if someone help me how to use this function.</p>
  
  <p>Thanks.</p>
