\brief Provides an extension that allows to inhibit the idle behavior of the compositor.
\sa WaylandSurface::inhibitsIdle
The IdleInhibitManagerV1 extension provides a way for a client to inhibit the idle behavior of
the compositor when a specific surface is visually relevant to the user.
IdleInhibitManagerV1 corresponds to the Wayland interface, \c zwp_idle_inhibit_manager_v1.
To provide the functionality of the extension in a compositor, create an instance of the
IdleInhibitManagerV1 component and add it to the list of extensions supported by the compositor:
\qml \QtMinorVersion
import QtWayland.Compositor 1.\1
WaylandCompositor {
IdleInhibitManagerV1 {
// ...
}
}
\endqml
Inhibited surfaces have the WaylandSurface::inhibitsIdle property set to \c true.
