Class TableauItem
Item to go insize a StripTableau widget.
This widget is designed to be placed within a StripTableau widget, to graphically display
a single channel of data. Ideally, this widget will not be instantiated
directly by the user, but rather indirectly via the StripTableau widget's
addChannel method.
Once instantiated the TableauItem associated with some data is
returned by both the addChannel and getChannel
methods of the StripTableau widget.
The TableauItem has a "metadata"
region on the right. This metadata region can display the name of the
channel and a close button by default, and optionally a caller-specified
component which can display additional information. To make this metadata
region visible, the caller should do the following:
-
Set the
metawidth instance variable to an
appropriate size (eg: 100).
-
Set the
name of the channel.
-
(Optional) Set the
meta instance variable to a
gtk.Widget subclass which is displayed beneath the label
and button.
