Added context menu -- single right click on a data item in the upper
TreeView window and a context menu opens on the right, choose where to plot
the item.  This becomes the default plotting location if you later double
click on an item.

Items chosen to plot from upper TreeView window will only appear once in the
lower ListView window (checks name, title, source, and type).

Also, more code clean-up (the "this" pointer was being deleted on exit even
though "this" was created on the stack and not on the heap???).

Modified TTriumfFileGui.h and .cxx to fix up drop down menus, putting in
check marks to denote which option is currently in effect.  Also, a few more
cosmetic changes.

Modified TTriumfFileGUI to draw in the first pad when the canvas
is divided into zones.  Also, a few cosmetic changes.

I commited fixes for a few annoying problems:
1) get rid of useless "delete/create TCanvas"
2) make the "zones" actually work
3) implement "draw in new canvas", "draw in current pad", "draw in next pad"
and "overplot in current pad"
4) consolidate all drawing into a single "DrawObject()" function.
K.O.

Somehow neither Joe nor myself were in the "cvs" group and could not commit
to the miroodas CVS. Fixed by editing root@dasdevpc:/etc/group + NIS reload.
K.O.

I commited a change to TTriumfFileGUI.cxx to silence the message "No Loaded
Online Histograms". K.O.

I commited a simplification of the Makefile:
- "make" now builds the GUI executable
- removed useless cruft for building the GUI on Solaris, RedHat 4.x, etc
K.O.

I removed Greg King from the MIROODAS email notification. K.O.

Joe Chuma commited some code cleanup and sundry unknown changes. K.O.

Here is the list of components that must/should be developed for MIROODAS:

1. Peak Finding Panel (1D w/ TSpectrum, 2D w/ TSpectrum2 ... note 2D is not
functional yet)
    *THIS is a new feature*
2. Fit Panel
    *This will be a remake of the old feature ... with some improvements*
3. Draw Options Panel
    *This will be a remake of the old feature ... with some improvements*
4. Stat Option Panel 
    *THIS is a new feature*
5. TCanvas
    including: custum context menus which will associate with the new features
6. TTreeViewer
    including: necessary bug fixes and developments as discussd in the meeting
7. Attributes Panel
    *Remake all Attributes Panels and combine into one panel*

> 2. Improved Fit Panel
> 3. Improved Draw Options Panel
> 5. TCanvas updates
> 6. TTreeViewer updates
> 7. Improve Attributes Panel

What are these "improvements" and "updates"? We cannot plan without good data.

K.O.

We will have the 10am meeting this Wednesday in the ISAC2 2nd floor kitchen.
Agenda:
 - progress reports
 - status of midas online connection (K.O.)
 - priority of improvements to the histogram viewer (TCanvas) and tree view
(TTreeViewer). (G.K.)
K.O.

I revived the test midas experiment on midtis06. We can start using it to
develop the online connection to the root gui. Here are the instructions
on running things:
 - login to midtis06
 - set ROOTSYS to /send/home/olchansk/daq/root
 - cd /send/home/olchansk/daq/root
 - ./start_daq (four xterm windows should open:
   1) mhttpd (on port 8080). Point a web browser to http://midtis06:8080
   2) odbedit
   3) a front end
   4) an analyzer)
 - run ~olchansk/daq/midas/linux/bin/rmidas
   enter "midtis06" in the "hostname" box.
   five histogram names should appear in the list on the left: CADC00
through 03 and ADCSUM. Click on the names to see the histograms.
 - start a run (from a web browser, or enter "start" in odbedit)
 - the frontend window should count 100 events/sec.
 - click on the rmidas "update" button, the counts should increment.
This is all done by vanilla ROOT and MIDAS.

The ROOT code to access the MIDAS histograms is in
~olchansk/daq/midas/src/rmidas.c, functions:
 - ConnectServer()
 - GetHistoList()
 - GetHisto()
 - ClearHisto()

miroodas code has been imported into the CVS and can be checkout

cvs -d /dasdevpc/cvsroot co miroodas

or

cvs -d gking@dasdevpc:/usr/local/cvsroot co miroodas
--using gking as an example user

Please see miroodas/doc/README.txt for more information on compiling
