Method
XdpPortallocation_monitor_start
Declaration [src]
void
xdp_portal_location_monitor_start (
XdpPortal* portal,
XdpParent* parent,
guint distance_threshold,
guint time_threshold,
XdpLocationAccuracy accuracy,
XdpLocationMonitorFlags flags,
GCancellable* cancellable,
GAsyncReadyCallback callback,
gpointer data
)
Description [src]
Makes XdpPortal start monitoring location changes.
When the location changes, the XdpPortal::location-updated.
signal is emitted.
Use xdp_portal_location_monitor_stop() to stop monitoring.
Note that XdpPortal only maintains a single location monitor
at a time. If you want to change the distance_threshold,
time_threshold or accuracy of the current monitor, you
first have to call xdp_portal_location_monitor_stop() to
stop monitoring.
This method completes asynchronously. Use xdp_portal_location_monitor_start_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
