Qt Application Manager



The application-manager binary (appman) is a headless daemon by itself. A suitable QML file needs to be supplied on the command-line or via a config file at startup, which will act as a compositing window manager using the APIs that are exported from the C++ side.

Please read the Introduction to the Qt Application Manager for a high-level overview of the package.
