Use external text editors

You can open files for editing in the default text editor for your system: Notepad on Windows and vi on Linux and macOS. To open the file you are currently viewing in an external editor, select Tools > External > Text > Edit with Notepad or Edit with vi, depending on your system.

Qt Design Studio looks for the editor path in the PATH environment variable of your operating system.
