(previous message was completely garbled by the Elog "ELCode" whatever it is)


Restored fixes (2) and (3) that were removed by a careless previous committer.

(Note this assumes windows has "setenv()", which I believe it does have, please
test compilation on Windows ASAP and let me know).

K.O.

Fixed: do not make a group named "-1" when TGTextDialog returns "-1" when
canceled; rationalize the host name and port number code; do not use hot
keys "O" and "C" in TGTextDialog as I could not enter an "O" or a "C" into
the text area (probably some conflict with X-Win32, but just as well to get
rid of it).

A memory leak was fixed in Roody.cxx, which occurred when updating a histogram
from a NetFolder object.

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 
 
K.O. 
 

The bottom canvas window has been removed.  The superfluous buttons have
been removed.  No response, yet, to my question in the ROOT forums regarding
inserting PeakFind in the pre-defined context menu when right-clicking on a
histogram.

The y-axis scales can now be fixed just like the x-axis scales.  Choose
YaxisLimits from the context menu when right-clicking on a histogram frame and a
small dialog box will open in which you can enter the min and max values.  If
the frame is part of a multipad canvas, all pads on that canvas will be redrawn
with the new scales.  Choose YaxisLimits again and click on the Unzoom button to
unzoom all pads on that canvas.

Two bugs were introduced yesterday...
 -- program crashes when trying to connect online via  roody -h nodename
    (uninitialized pointer)
 -- program crashes when restoring an xml file which tries to use the
    external dtd file (unchecked error condition)
Both problems are now fixed.

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.

Attached is a cvs patch to allow roody to display graphical cuts (TCutG).

Does somebody have the permissions to commit this patch to the cvs repository?

It also includes some hooks where code for updating a cut will be implmented.
Updating cuts will be done with another patch, to both roody and midas.  This same
mechanism can be used for creating new cuts and sending them to the analyzer.

The final part of this project will be a change to midas to allow cuts to be booked
into (sub)folders.  I have some code which I am using for testing purposes, but I
don't like where it stores the cuts for persistence between different invocations of
the analyzer.  I'm thinking that cuts should be stored in last.root, and retrieved
from there.

cvs commit made today to support display of polygons, and sending polygons an analyzer.
A patch for mana.c so that MIDAS analyzers receive polygons has been sent to Stefan.

Patch has been submitted to CVS so mana.c is up-to-date.

- Stefan

I have just sent a MIDAS patch to Stefan so that:

(1) cuts should be booked using TCutG *cut_book( const char *name).
    Usage is similar to h1_book etc.

(2) cuts are saved in last.root.

(3) cuts are restored from last.root.

I also fixed a bug in receiving cuts from ROODY.  The search for
cuts should be made only in gManaHistosFolder, not from gROOT.
Should this also be the case for GetPointer etc.?

I believe this implements a first pass at handling TCutG for MIDAS and ROODY.
To create a cut from scratch, one declares it in the analyzer init functions
using cut_book, and saves the pointer for use in the event-by-event code.
Then in ROODY, create a polygon, name it and send it to the analyzer (right click
on the polygon).

I believe the patchs which I have made should also be applied to ROME.

John.

I have talked with Pierre-Andre and Stefan over the last few days about the need
to be able to display graphical cuts (TCutG) in Roody, and also to be able to
change them and send them back to the analyzer.

I expect to have some sample code for putting cuts into a folder sometime soon.

Command line argument change:
   the space between -h and hostname is optional
   the space between -r and filename is optional

The save file is now an xml file validated with roody.dtd

When saving or restoring, if you enter a filename without an extension,
.xml will be appended.  The previous save file format is no longer
supported.

New files:  RoodyXML.h, RoodyXML.cxx, roody.dtd

Fixed up group problems when an online file is located in a folder.

Makefile modified to support libxml2.

When the number of zones (sub-pads) is changed, any histograms on the active
canvas will be redrawn on the new canvas.  Also, more general code clean-up.
