Last change on this file since 1731 was 1724, checked in by Kana Sugimoto, 15 years ago

New Development: Yes

JIRA Issue: Yes (CAS-1801)

Ready to Release: Yes

Interface Changes: Yes

What Interface Changed: two classes, CustomToolbarTkAgg and CustomToolbarCommon,

are created to a new module casatoolbar

Test Programs: run sdplot with plottype='spectra' and 'totalpower'

Put in Release Notes: Yes/No

Module(s): CASA task sdplot, sdbaseline, sdstat, sdfit

Description:

Two new classes, CustomToolbarTkAgg and CustomToolbarCommon, are
created to a new module casatoolbar in order to remove backend dependency
of sdplot(). The other code are modified accordingly.
The additional toolbar, casabar, is now default in ASAP plotter
(asapplotter.plot and asapplotter.plottp).
