Forgot to mention the main reason of this update: when looking at ROOT files, ROODY could not open any subdirectories because of some name 
changes inside ROOT. Now fixed.

ROODY svn rev 236

It is possible that you are referencing the SVN repo using the "svn:" access method. This access method was recently 
disabled.

Please switch to the "https:" method (username/password svn/svn) using this command:

cd .../roody
svn switch --relocate svn://ladd00.triumf.ca/roody https://ladd00.triumf.ca/svn/roody

I removed the checks for ROOTSYS being the same at run time and compilation time. 
These checks never worked right and are unnecessary since we always install roody 
separately for each experiment and ROOTSYS settings are always consistent.

The "Zones" manu has not been working right - if you have a canvas open with one 
histogram plotted and you select Zones "2x2", nothing happens. The expected 
action is to have the canvas divide itself into 4 pads (2x2) and the one 
histogram to show up in the first pad. That's how it works now.

svn rev 240.

I created a CVS repository for the ROOT GUI project: 
/dasdevpc/cvsroot/rootgui (dasdevpc:/usr/local/cvsroot/rootgui) 
 
(should I rename it to cvsroot/miroodas?).

We will have our regular meeting this Tuesday at 10am in the ISAC2 2nd 
floor kitchen. 
 
Agenda: 
 -review of assigned homework (I did most of mine!). 
 -layout of our cvs repository

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()

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.)

I removed Greg King from the MIROODAS email notification. 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 commited a change to TTriumfFileGUI.cxx to silence the message "No Loaded
Online Histograms". 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 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.

> There are still problems to overcome:

a second time);

problem confirmed.

problem confirmed.

right.

> - need to figure out a way to let the user choose the active pad, so he/she
can pick any drawn histogram for peak finding (currently it only works with the
latest drawn histogram).

the current pad (gPad) is selected by clicking on it with the middle mouse
button. This has always worked and it still works (for me).

> - Clear All online histograms has been added to the main menu (it used to be
a button).

right.
