Q_INVOKABLE void DisplayVisual

(

bool

_value

)

Set whether to display the frustum visual.

Parameters

[in]

_value

Boolean value for displaying the visual

eventFilter()

bool eventFilter ( QObject *  _obj, QEvent *  _event  )

override

LoadConfig()

void LoadConfig ( const tinyxml2::XMLElement *  _pluginElem )

override

LoadFrustum()

void LoadFrustum

(

)

Load the scene and attach FrustumVisual to the scene.

OnCameraInfo()

void OnCameraInfo

(

const msgs::CameraInfo &

)

Callback function to get data from a CameraInfo message.

Parameters

[in]

_msg

CameraInfo message used to compute frustum information

OnRefresh()

Q_INVOKABLE void OnRefresh

(

)

Callback when refresh button is pressed.

OnScan()

void OnScan

(

const msgs::LogicalCameraSensor &

_msg

)

Callback function to get data from a LogicalCameraSensor message.

Parameters

[in]

_msg

LogicalCameraSensor message with frustum information

OnTopic()

Q_INVOKABLE void OnTopic

(

const QString &

_topicName

)

Set topic to subscribe for frustum data.

Parameters

[in]

_topicName

Name of selected topic

SetTopicList()

Q_INVOKABLE void SetTopicList

const QStringList &

_topicList

)

Set the list of topics.

Parameters

[in]

_topicList

Topic list

TopicList()

Q_INVOKABLE QStringList TopicList

(

)

const

Get the list of topics as a string list.

Returns

Supported topic list

TopicListChanged

void TopicListChanged ( )

signal

Notify that topic list has changed.

Update()

void Update ( const UpdateInfo &  _info, EntityComponentManager &  _ecm  )

overridevirtual

Update callback called every time the system is stepped. This is called at a Gazebo Transport thread, so any interaction with Qt should be done through signals and slots.

Parameters

[in]	_info	Current simulation information, such as time.
[in]	_ecm	Mutable reference to the ECM, so the system can read and write entities and their components.

Reimplemented from GuiSystem.
