How To

# Configure QML Language Server

Since Qt 6.4, QML Language Server offers code completion and issues warnings for QML.

To set preferences for QML Language Server, go to Preferences > Language Client > General and select QML Language Server.

## Turn off QML Language Server for all projects

To globally turn off QML Language Server, clear the QML Language Server checkbox.

For more information about how to turn on and off language servers for a particular project, see Configure language servers for projects.

## Use advanced features

By default, QML Language Server issues warning messages and provides code completion, while the embedded code model handles advanced features, such as renaming symbols and finding usages.

To disable the embedded code model and use QML Language Server for everything, select Use advanced features.

## Select QML Language Server version

Qt Creator tries to use QML Language Server shipped with the Qt version in your current kit. To override that behavior and always use QML Language Server of the highest registered Qt version, select Use from latest Qt version.

To use older QML Language Server versions, select Allow versions below Qt 6.8.

## Automatically configure new CMake projects

To automatically configure new CMake projects, select Create .qmlls.ini files for new projects.
