Detailed Description¶
The purpose of area monitoring is to inform a user when he/she comes close to an area of interest. In general such an area is described by a
QGeoCircle. The circle’s center represents the place of interest and the area around it identifies the geographical region within which notifications are sent.A
QGeoAreaMonitorInfoobject is valid if it has a non-empty name and a validarea(). Such objects must be registered with aQGeoAreaMonitorSourceto start and stop the monitoring process. Note that extensive monitoring can be very resource consuming because the positioning engine must remain active and has to match the current position with eachQGeoAreaMonitorInfoinstance.To further reduce the burden on the system there are optional attributes which can set. Each monitored area can have an expiry date which automatically removes the to-be-monitored area from the monitoring source once the expiry date has been reached. Another option is to adjust the persistence of a monitored area. A
QGeoAreaMonitorInfothatisPersistent()will remain active beyond the current applications lifetime. If an area is entered while the monitoring application is not running the application will be started. Note that this feature is not available on all platforms. Its availability can be checked viasupportedAreaMonitorFeatures().See also
- __init__(other)¶
- Parameters:
other –
QGeoAreaMonitorInfo
Constructs a
QGeoAreaMonitorInfoobject as a copy ofother.- __init__([name=""])
- Parameters:
name – str
Constructs a
QGeoAreaMonitorInfoobject with the specifiedname.See also
Returns the boundaries of the to-be-monitored area. This area must not be empty.
See also
Returns the expiry date.
After an active
QGeoAreaMonitorInfohas expired the region is no longer monitored and theQGeoAreaMonitorInfoobject is removed from the list ofactive monitors.If the expiry QDateTime is invalid the
QGeoAreaMonitorInfoobject is treated as not having an expiry date. This implies an indefinite monitoring period if the object is persistent or until the current application closes if the object is non-persistent.See also
- identifier()¶
- Return type:
str
Returns the identifier of the
QGeoAreaMonitorInfoobject. The identifier is automatically generated upon construction of a newQGeoAreaMonitorInfoobject.- isPersistent()¶
- Return type:
bool
Returns true if the
QGeoAreaMonitorInfois persistent. The default value for this property is false.A non-persistent
QGeoAreaMonitorInfowill be removed by the system once the application owning the monitor object stops. Persistent objects remain active and can be retrieved once the application restarts.If the system triggers an event associated to a persistent
QGeoAreaMonitorInfothe relevant application will be re-started and the appropriate signal emitted.See also
- isValid()¶
- Return type:
bool
Returns true, if the monitor is valid. A valid
QGeoAreaMonitorInfohas a non-emptyname()and the monitored area is notempty(). Otherwise this function returns false.- name()¶
- Return type:
str
Returns the name of the
QGeoAreaMonitorInfoobject. The name should be used for user-visibility purposes.See also
- notificationParameters()¶
- Return type:
Dictionary with keys of type .QString and values of type QVariant.
Returns the set of platform specific parameters used by this
QGeoAreaMonitorInfo.See also
- __ne__(rhs)¶
- Parameters:
rhs –
QGeoAreaMonitorInfo- Return type:
bool
Returns
trueif any of thelhsobject’s values are not the same as those ofrhsobject. Otherwise returnsfalse.- __eq__(rhs)¶
- Parameters:
rhs –
QGeoAreaMonitorInfo- Return type:
bool
Returns
trueif all of thelhsobject’s values are the same as those ofrhsobject. Otherwise returnsfalse.Sets the to-be-monitored area to
newShape.See also
Sets the expiry date and time to
expiry.See also
- setName(name)¶
- Parameters:
name – str
Sets the user visibile
name.See also
- setNotificationParameters(parameters)¶
- Parameters:
parameters – Dictionary with keys of type .QString and values of type QVariant.
Sets the set of platform specific
parametersused byQGeoAreaMonitorInfo.See also
- setPersistent(isPersistent)¶
- Parameters:
isPersistent – bool
Sets the
QGeoAreaMonitorInfoobject’s persistence toisPersistent.Note that setting this flag does not imply that
QGeoAreaMonitorSourcesupports persistent monitoring.supportedAreaMonitorFeatures()can be used to check for this feature’s availability.See also
- swap(other)¶
- Parameters:
other –
QGeoAreaMonitorInfo
Swaps this
QGeoAreaMonitorInfoobject withother. This operation is very fast and never fails.
