Member Function Documentation

template<class T >

bool swri_console::NodeClickHandler::callService	(	ros::ServiceClient &	client,
		T &	service,
		int	timeout_secs = 5
	)		[inline, private]

Attempts to call a ROS service. Will time out and return false if the service call does not return within a specified time.

This is *so* ugly, but some sort of hack like this is necessary for keeping the UI responsive; ROS service clients do not have any built-in timeout mechanism, so we have to wrap our own around the service call. If we don't, a call to a hanged node could spin forever.

Template Parameters:

T	Type of the ROS service

Parameters:

client	An initialized ros::ServiceClient
service	An instance of the ROS service
timeout_secs	The number of seconds to wait before timing out

Returns:

true if the service call completed successfully, otherwise false

template<class T >

void swri_console::NodeClickHandler::callServiceWorker	(	ros::ServiceClient &	client,
		T *	service,
		bool *	success
	)		[inline, private]

Used by callService() to actually call the service in another thread.

bool swri_console::NodeClickHandler::showContextMenu	(	QListView *	list,
		QContextMenuEvent *	event
	)		[private]

Normally this call should return very quickly, but we don't want the GUI to hang if the roscore is stuck, so add a timeout. The value is pretty arbitrary, but we also want to give enough time for this to still respond over a slow network link, so it shouldn't be *too* small.
