When using the QtWebEngine, you can enable the chromium debug dev tools with setting the QTWEBENGINE_REMOTE_DEBUGGING environment variable. Normally Chromium creates a DevToolsActivePort file, which contains the information about the debug port. However when using the QtWebEngine, this file is not created. How can I make Qt/Chromium create this file?

  • Why do you want the file? Commented Jul 9, 2022 at 18:10
  • To get the debug port and websocket address. Commented Jul 9, 2022 at 22:34
  • Set the port to whatever you like. See this answer. Commented Jul 10, 2022 at 0:23
  • The tricky part is the websocket address since it contains a GUID. While I found a workaround (see this answer), the general question still stands. Commented Jul 10, 2022 at 0:43
  • What evidence do you have that chromium "normally" creates this file? The relevant part of the source code noted in your other question suggests this is not the case: it's only written if the output_directory is set, which comes from a command-line argument specific to Torque; there's no default if the option isn't set. But in any case, you still haven't given a valid reason why you would need this file, since the information can already be obtained by other means. Commented Jul 10, 2022 at 10:39
