Qt Application Manager


The application manager binary (appman) is a headless daemon by itself. You need to supply a suitable QML file via the command-line or via a config file at startup, which then acts as a compositing window manager using the APIs that are exported from the C++ side.

For a high-level overview, see Introduction to the Qt Application Manager.
