FAQ - Integration Between Qt Design Studio and Qt Design Studio

Is there a way to automatically propagate name changes between Qt Design Studio and Qt Design Studio?

Unfortunately we do not automate renaming files between tools at the moment. If you decide to change the name of a property, alias, or signal in Qt Design Studio, you need to manually change the name in Qt Design Studio to maintain the connection. However, you can rename symbols in all files within a project. To rename a QML type in a project, select Tools > QML/JS > Rename Symbol Under Cursor or press Ctrl+Shift+R. For more information, see Renaming Symbols.
