Externaly open local HTML file

[DavidM29]

Hello,
I would like to open a local HTML file on the computer web browser.
But I don't know how to achieve this. Can somebody help me ?
I tried this :

Qt.openUrlExternally("help.html")

but it does not work : here is the error message I have :

ShellExecute 'qrc:/help.html' failed

@DavidM29 it seems you need to fully qualify the page you want to open.

Qt.openUrlExternally("http://some-server-name-or-ip/help.html")

or

Qt.openUrlExternally("file:///path/to/help.html")

How about this?

QDesktopServices::openUrl(QUrl("help.html"));

@Pablo-J-Rogina @kenchan
Thank you for those answer !
This line worked :

Qt.openUrlExternally("file:///path/to/help.html")

I also tried @kenchan's solution but it did not work Qt can't find QUrl so maybe problem with a missing import. But anyway find a good solution.
