chromium embedded framework: file type filter in a dialog box

Question

I am working with the cef dialogs to filter the viewable file types inside the dialog box

I only want the user to see common image files like jpeg, gif, png. So far I have something that works but in the dialog box, the option is titled PNG Images. That is wrong because it should be just Images not PNG Images.

I tried following the sample that came with cef and building off it. (sample)

My code is

  std::vector<CefString> file_types;
  file_types.push_back(".png;*.jpg;*.jpeg;*.gif");
  browser->GetHost()->RunFileDialog(FILE_DIALOG_OPEN, "Open Icon File",
    "", file_types, new RunFileDialogCallback(message_name));
  return true;

The following works

file_types.push_back(".png;*.jpg;*.jpeg;*.gif"); 

But I do not know how to give this filter a name

Answer 1

Maybe it will be usefull for someone in 2022, who use jcef (java cef):

Vector<String> file_types = new Vector<String>();
file_types.add(".csv");
manager.getBrowser().runFileDialog(CefDialogHandler.FileDialogMode.FILE_DIALOG_OPEN, "Choose CSV", null, file_types, 0, dialogCallBack);
}
