Opening a .py script from Qt (not running) in the default/user defined editor

[gde23]

Hello,

I want to open a python script from withing Qt.
The file should not be executed, it just should be opened with the default python-editor the user has installed.
Or as alternative the user should be able to specify the path to the editor to open the file with.

How would you typically do this?

Sounds like a job for QDesktopServices::openUrl(): https://doc.qt.io/qt-5/qdesktopservices.html#openUrl

This relies on the user configuring the OS to launch the editor when the user double-clicks the .py file on the desktop or file viewer app (e.g. Windows Explorer, Nautilus)

@JKSH Thanks for the quick reply. I also though about QDesktopSevice, but will this work?
Since when I click a python scrip on my system it gets executed and not opened in any editor?
And what would be the way if the user has explicitly specified a path to the editor to use?

Ah, OK. In that case, you can use QProcess to launch the editor application and pass the .py file as an argument:

QProcess proc;
proc.startDetached("C:/Program Files (x86)/Notepad++/notepad++.exe", {"D:\\Project\\src\\hello.py"});

@JKSH Thanks a lot, that works the way I need it.
I also noticed that QDesktopService will still open the file in the editor (even when its executable and clicking calls python)
