This megawidget displays statistics about the fragments that have been removed from source queues. It consists of a summary region that shows the total number of fragments and a per-queue area that shows the fragments removed from each queue.
See the OPTIONS and METHODS sections below for information that describes how to control the contents of those sections.
-totalfragmentsSets the total number of fragments emitted. This value appears in the summary region of the widget.
The configure and cget methods operate just like those methods for any other Tk widget.
$window addSource srcid fragments
Sets source output statistics. srcid
is the id of a dta source. fragments
is the number of fragments ordered from that queue
(and output). If necessary, a new row in the
per source statistics region is created for this
data source.
$window clear ?value?
Clears the output counts on all sources. If
the optional parameter value
is supplied all source counts are set to that value.
Otherwise all source counts are set to zero.
$window reinit
Reinitializes the per-source region of the widget by removing all sources ids and their associated counter.
$window listSources
Returns a list of the source ids that are currently known to the per source statistics. region. Note that if called just after a reinit, this will return an empty list.
