Detailed Description

Base class for statusbar items.

Each item represents functionality (or action) controlled by statusbar and related to MapFrame. One item is usually connected with one widget but it is not necessary. Item can represent property (depends on manager). Items are not widgets but can provide interface to them. Items usually has requirements to MapFrame instance (specified as MapFrame.methodname or MapWindow.methodname).

Todo:

consider externalizing position (see SbProgress use in SbManager)
