Never mind that.

Vertical scale of online histograms *has* to change after a refresh- the number of
counts in an online histogram increases as it accumulates more data and the histogram
would grow up out of the visual range unless it is rescaled.

Now, we can be smart about this: for a zoomed histogram, we can freeze the "y" scaling
or we can maintain the zoom ratio while rescaling.

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 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.

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.

Committed MainFrame.cxx/.h with a fix for the problem of segmentation faults
while updating online histograms.  The problem was the pointers to the
histograms needed to be changed in the TGLVContainers when the histograms
were deleted and recreated due to being updated.  The main difficulty was
getting a handle on which TGLVEntry matched which histogram, when the
histogram pointers were obtained from the TPad and not the TGLVContainer. 
Anyway, you can now view online histograms without the program crashing.

The original "main.cxx" always produced "segmentation fault" on my system. So I 
rewrite a new one as the attached "main_el.cxx". It works stable on my systems. I 
use "getopt.h" to parse the command line options. Also, the options are altered 
as the following:
-------------------
--mhost, -M <mhost>   connect to MIDAS server <mhost>
--rhost, -R <rhost>   connect to ROOT server <rhost>
--port, -p <port>     connect to port <port>
--config, -c <xml>    Using config file <xml> in XML format
-------------------
The main_el.cxx doesn't pass options to TApplication except root file names. 
Please see the source in detail. I hope it may help.

FYI, I am presently working in an updated version of roody.

The user interface, GUI and user-visible functionality I am leaving alone. The under-the-hood handling of 
histogram data I am reworking using our latest understanding of the workings of ROOT (object ownership, 
etc) and C++ (hey, with STL std::map, C++ is as easy as perl!).

The updated version may also fix some of the existing problems- crashes caused by confused object 
ownership rules, long startup times (current code has to look at every existing histogram before starting- 
slow if many histograms in an online folder) and inability to display TGraph objects (that is what started 
me working on the code).

While at it, we will move the Roody code repository from CVS to SVN.

K.O.

> FYI, I am presently working in an updated version of roody.

The new version of Roody has been commited.

It has been tested only on Linux (SL4.3) and while we are shaking out the new bugs,
all are welcome to try it and report any problems. It should not eat your data.

If the new version does not work for you at all, the old version was preserved as
an SVN branch, accessible using this SVN command:
svn checkout svn://ladd00.triumf.ca/roody/branches/roody-v1 roody-v1

The peak find panel has been added to MIDASviewer.  Click on the speed
button to open the panel.  Click the Find button to find peaks, and do a fit
if the attempt to fit check box is checked.  Fitting seems slow, but that is
all internal to ROOT.

Requirement List:
================
- To be done                   SW : Selection window
= Done                         GW : Graphic window
> Problem

1) Online capability
====================
- Socket connection to the Midas analyzer for histogram display.
- The Tree is not yet to be considered as yet not implemented in Root (Circular
buffer, NetTDirectory).
= done - Option of specifying the host name AND port number has to be present to
allow multiple parallel Miroodas session connected to different analyzer.
= done - Multiple Miroodas connecting to a given Midas experiment is already
available through the Midas analyzer local Root server.
= Retain the host:serverport for reconnection due to lost of possible communication
with the analyzer.
- Add RBclick for online disconnect.

2) Histogram update
===================
- While in online mode, simple mean of switching on/off the histogram update
with options such as: Single shot update, pause/resume update, change update
frequency need to be implemented.
- The update frequency is global to the application and therefore appears in a
pull-down menu in the SW.
- While the "Refresh", "Off", "On" are in the menu bar, should also be present in the
RBClick menu in either the SW or GW.

3) Open Offline Files
=====================
Possibility of concurrently open multiple files of the .root AND .hbook
file type. So far only the histogram part of the content of the files are
retrieved for display.
= The histogram list appears in a unique window and can be mixed with the
Online histogram (SW).
= The mode of histogram reference display may be using a tree listing.
= In that case the description string should merge information such as the
file name or run number in order to distinguish from the similar open files
containing equivalent histogram name.
> the Tree structure branch provide the open file name.

4) Multiple Selection buttons
=============================
> From the SW possibility of multiple selection using the standard Ctl/Alt
key should be available. Currently ROOT may not provide such option (contact
with René Brun for confirmation of this lack of flexibility).
Appears not possible, KO will look into ROOT code for implementation.

5) Grouping Histogram
=====================
Grouping is a feature allowing the display in a single operation of a
predefined set of histograms. Inital thoughts on that subject tend to suggest
that a group must be reference to the histogram name or histogram title only.
In the ONLINE mode this reference is correct as the histogram are re-used over
the multiple runs (the saving of the histograms themselves is done through
the analyzer, Miroodas doesn't have knowledge of the run state at this point
of development). For OFFLINE use, the group should also be only referenced to
the histogram name or title as the same group name could be used for
retrieving the same set of histograms from different files (different run).
The implementation of the manipulation of the group list (creation/add/remove)
is not yet defined.
= Jun 2004: main development topic (GROUPING).
= RULE: All histos of a given group cone from the same source.

6) Selection display option
===========================
= Once the selection from the SW is performed, option for the destination
selection display should permit "new canvas", "Overlay", "Replace" actions.
- Option to maintain Xscaling on different histo display.
- In the "Overlay" case option for color cycling should be available.

7) Save/Restore Configuration
=============================
= Possible save-set of the current SW is required for later quick restore
of the application state.
- The saved configuration could also include the graphical canvas characteristics.

8) Save/Restore selected histogram
==================================
- Possibility of saving a group to a file (.root) should be available.
- Possible automatic "group save" request during application termination may
be foreseen.

9) Zooming option
=================
= Zooming should survive the Online update (keep the associated zooming
parameter at the histogram level).
- hold refresh while selecting zoom option (prevent redisplay).

10) Offline file update
======================
- Possible update of the opened file can be investigated. This would allow
external application to update .root file opened by Miroodas.

11) PeakFinder() option
=======================
= done - Greg King PeakFinder() method should be part of the Miroodas.
= invoked by RBClick on the GW.

12) Pre-programmed fit
======================
- Possible extension of the list of pre-program fit function. This could be
part of the configuration file.

13) TreeViewer invocation
=========================
While Histogram is so far the only object handled by the online Miroodas
application, the offline file may contain Tree objects.
= Option for launching TTreeViewer() is beneficial.

14) Application argument option
===============================
- The Miroodas application should be able to take multiple combination of
command line arguments such as:
= initial .root, .hbook file 
= Argument option -Rfile.save for configuration (include groups).
= host name and port number for ONLINE access (-Hhost:port).
- log file description for debugging purpose.
---------------------------------------------------------------------
Current state of options:
> TTriumfFileGUI -h
USAGE:
TTriumfFileGUI [-h] [-Hhost[:port]] [file.root ...] [file.hbook ...]
Options :
   -h            - display usage
   -Hhost[:port] - connect to midas analyzer on given host and port
   file.root     - load .root files
   file.hbook    - load .hbook files
   -Rsavefile    - restore savefile
---------------------------------------------------------------------

15) Zone option
===============
= Predefine set of Zone should be available.

16) Block incrementation
=========================
In the case of a multiple CONSECUTIVE histogram selection, the Right Button
Click (RBClick) should provide option for displaying the "next block" of
histograms. The "next block" refers to the immediate following consecutive "not
yet selected" set of histograms. This option should follow the previous display
setting (ie: override canvas/new canvas, etc ). This permits a quick scan of
histogram before the block is referenced as a group by assigning a name to the
histogram set (RBClick option). 
> Depend on the mouse selection option... (see pt4).

17) Group naming in graphical canvas
====================================
- When in GW for group or block, RBClick should provide respectively the
renaming/naming of the group/block.

18) Persistence of the Xscale
=============================
- In the GW the RBClick should provide the option to freeze the last Xscale or
Yscale setting for later application to newer GW display.

19) Xscale applied to whole canvas
==================================
- In the case of a multiple histogram display (group or block), RBClick should
allow an option to apply automatically the last Xscale (or Yscale) setting to
the whole GW set of histograms.

20) Histogram Clear
===================
As for the 2) the clear action should be available at all the different CS
levels in either the SW or GW.

21) Histogram info box
======================
= Add run number extracted from the opened file name in the GW below the histogram name.
- Add possible run number extracted from online in the GW below the histogram name.
 
22) Temporary folder
====================
- Implement Temporary Tree for snapshot of any GW histogram content.

The peak finder context menu item was present only for TH1D histograms and
absent in all other histograms. I fixed this by explicitely adding this item
to the class menu of all TH1X classes. K.O.

I'm having a Roody refresh problem: when I draw groups in online mode the entire
canvas is refreshed with the most recently selected single histogram, instead of
the group.  I used svn to install the most recent version (svn checkout
svn://ladd00.triumf.ca/roody/trunk roody).  Any help would be greatly appreciated!
