RosTopicProperty * marker_topic_property_
Subscriber subscribe(const std::string &topic, uint32_t queue_size, void(T::*fp)(M), T *obj, const TransportHints &transport_hints=TransportHints())
virtual bool setValue(const QVariant &new_value)
Set the new value for this property. Returns true if the new value is different from the old value...
Definition: property.cpp:130
virtual int getInt() const
Return the internal property value as an integer.
Definition: int_property.h:73
ros::NodeHandle update_nh_
A NodeHandle whose CallbackQueue is run from the main GUI thread (the "update" thread).
Definition: display.h:269
IntProperty * queue_size_property_
virtual void subscribe()
Overridden from MarkerDisplay. Subscribes to the marker array topic.
virtual void setDescription(const QString &description)
Set the description.
Definition: property.cpp:164
bool isEnabled() const
Return true if this Display is enabled, false if not.
Definition: display.cpp:281
void incomingMarkerArray(const visualization_msgs::MarkerArray::ConstPtr &array)
Process a MarkerArray message.
void setMessageType(const QString &message_type)
ros::Subscriber array_sub_
std::string getTopicStd() const
Display for an array of markers. The MarkerDisplay class handles MarkerArray messages. This is just a wrapper to let MarkerArray topics get selected in the topic browser.
virtual void unsubscribe()
Overridden from MarkerDisplay. Unsubscribes to the marker array topic.
#define PLUGINLIB_EXPORT_CLASS(class_type, base_class_type)
Displays "markers" sent in by other ROS nodes on the "visualization_marker" topic.
void handleMarkerArray(const visualization_msgs::MarkerArray::ConstPtr &array)
virtual void setStatus(StatusProperty::Level level, const QString &name, const QString &text)
Show status level and text. This is thread-safe.
