Called by setFixedFrame(). Override to respond to changes to fixed_frame_.

Reimplemented from rviz::Display.

Definition at line 449 of file marker_display.cpp.

void rviz::MarkerDisplay::incomingMarker ( const visualization_msgs::Marker::ConstPtr & marker ) [private]

ROS callback notifying us of a new marker.

Definition at line 234 of file marker_display.cpp.

void rviz::MarkerDisplay::incomingMarkerArray ( const visualization_msgs::MarkerArray::ConstPtr & array ) [protected]

Process a MarkerArray message.

Definition at line 223 of file marker_display.cpp.

void rviz::MarkerDisplay::onDisable ( ) [protected, virtual]

Derived classes override this to do the actual work of disabling themselves.

Reimplemented from rviz::Display.

Definition at line 118 of file marker_display.cpp.

void rviz::MarkerDisplay::onEnable ( ) [protected, virtual]

Derived classes override this to do the actual work of enabling themselves.

Reimplemented from rviz::Display.

Definition at line 113 of file marker_display.cpp.

void rviz::MarkerDisplay::onInitialize ( ) [virtual]

Override this function to do subclass-specific initialization.

This is called after vis_manager_ and scene_manager_ are set, and before load() or setEnabled().

setName() may or may not have been called before this.

Reimplemented from rviz::Display.

Definition at line 79 of file marker_display.cpp.

void rviz::MarkerDisplay::processAdd ( const visualization_msgs::Marker::ConstPtr & message ) [private]

Processes an "Add" marker message.

Parameters:

message The message to process

Definition at line 282 of file marker_display.cpp.

void rviz::MarkerDisplay::processDelete ( const visualization_msgs::Marker::ConstPtr & message ) [private]

Processes a "Delete" marker message.

Parameters:

message The message to process

Definition at line 392 of file marker_display.cpp.

void rviz::MarkerDisplay::processMessage ( const visualization_msgs::Marker::ConstPtr & message ) [private]

Processes a marker message.

Parameters:

message The message to process

Definition at line 259 of file marker_display.cpp.

void rviz::MarkerDisplay::reset ( ) [virtual]

Called to tell the display to clear its state.

Reimplemented from rviz::Display.

Definition at line 456 of file marker_display.cpp.

void rviz::MarkerDisplay::setMarkerStatus	(	MarkerID	id,
		StatusLevel	level,
		const std::string &	text
	)

Definition at line 207 of file marker_display.cpp.

void rviz::MarkerDisplay::setTopic	(	const QString &	topic,
		const QString &	datatype
	)		`[virtual]`

Set the ROS topic to listen to for this display.

By default, do nothing. Subclasses should override this method if they subscribe to a single ROS topic.

setTopic() is used by the "New display by topic" window; it is called with a user selected topic and its type.

Parameters:

topic	The published topic to be visualized.
datatype	The datatype of the topic.

Reimplemented from rviz::Display.

Definition at line 462 of file marker_display.cpp.

void rviz::MarkerDisplay::subscribe ( ) [protected, virtual]

Subscribes to the "visualization_marker" and "visualization_marker_array" topics.

Reimplemented in rviz::MarkerArrayDisplay.

Definition at line 137 of file marker_display.cpp.

void rviz::MarkerDisplay::unsubscribe ( ) [protected, virtual]

Unsubscribes from the "visualization_marker" "visualization_marker_array" topics.

Reimplemented in rviz::MarkerArrayDisplay.

Definition at line 163 of file marker_display.cpp.

void rviz::MarkerDisplay::update	(	float	wall_dt,
		float	ros_dt
	)		`[virtual]`

Called periodically by the visualization manager.

Parameters:

wall_dt	Wall-clock time, in seconds, since the last time the update list was run through.
ros_dt	ROS time, in seconds, since the last time the update list was run through.
