anoncvs account is not working anymore.

Please fix that.

Thanks

What was the fix? I do not think it was ever broken, except for the name change from "miroodas" to "roody", which I could not document until Pierre restored this Elog forum 
a few hours ago. K.O.

Added:  current online host name is now displayed in dialog box
Fixed:  online histograms can now be added and displayed in groups

A timer has been added to check if the online socket remains valid.  If, say,
the analyzer has been stopped while running Roody, this will be detected and the
connection closed, then, every second, that connection will be attempted until
successful.  Also, the external dtd file, roody.dtd, has been eliminated in
favour of internal dtd verification. Please note that Roody is being linked with
Root version 4.00.08, as version 4.02.00 introduces problems, such as context
menu errors.

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

The Makefile bits for building roody on MacOSX have been commited, tested on
MacOSX 10.3.9 with an unknown version of ROOT. Caveats: there is no support for
linking the roody shared library (volunteers are welcome!); there are warnings
about a double-include of libz when linking "roody" (ignore them). K.O.

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???).

Added:
  right click on filename (under Offline) brings up "Close file" option;
  automatic creation of TEMP folder (under Offline);
  right click on Groups folder brings up "Make new group" option
    which brings up a text dialog requesting a group name, which must
    be a new name;
  right click on a group name brings up "Delete group" and "Draw" options,
    "Delete group" does just that, while "Draw" automatically creates a
    new canvas divided into #pads = #histograms in the group and draws 
    the histograms one per pad;
  right click on a histogram brings up the context menu with added option
    "Add to group", which in turn brings up the list of existing groups

The group context menu options are changed to "Draw group", "Reset group" and
"Delete group", where "Reset group" means reset any online members of the group
and will only appear if there are online members in that group.  Multiple
selections (left click while holding down the control key) now have a context
menu (right click to open) but the context menu for multiple selections will
only display "New canvas", "Add to group" and, if there are online members,
"Reset", since the options "Current pad", "Overlay on pad" and "Next pad" are
not relevant to multiple selections.  Online folders now have a context menu
with "New canvas", "Add to group" and "Reset" options.

implemented context menu when right clicking on an online histogram in the
upper TreeView, also eliminated duplicate entries for online histograms in
the lower ListView.

PeakFind has been added to the context menu when right clicking on a drawn
histogram.  There are still problems to overcome:  the PeakFind panel needs
to communicate back to the gui that it has been deleted (to overcome a
segmentation violation error when the pointer is deleted a second time);
multiple PeakFind menu items appear when the canvas is split into multiple
pads (even though it is not added if already in the menu???); still no way
found to get a context menu for the folder icons (Files, Online, Groups);
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).  Also, Clear All online histograms has been
added to the main menu (it used to be a button).

right.

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).

right.

This is because you delete it twice- (1) after the users hits the "close" button,
(2) when the destructor is called from TTriumfFileGUI::PeakFind().

I think we should create the peak finder panel once and then hide and show it as
need. I will commit a fix shortly.

This is because Joe's check for duplicate menu items is broken (uses the wrong
object name). I simplified this by adding the menu item to the "TH1" class context
menu exactly once in the TTriumfFileGUI constructor. Will commit shortly.

Fixed. The peak finder is created once, never destroyed. Window is opened and
closed as needed.

> > - multiple PeakFind menu items appear when the canvas is split into multiple

Fixed. "PeakFind" menu item is added once in the viewer constructor.

I am looking into it.

In the mean time, I copied&kludged code from TGFrame.cxx to make the popup menu pop
at the pointer position.

Also if histogram is plotted from context menu, the "plot in" menu setting is left
unchanged.

The other problem is multiple selection of histograms. Looking into it.

I do not understand the difficulty- context menus for all menu items work the same way,
so once we know how to implement contect menus for histograms, other context menus are
done the same way. As an example, I added context menus to all non-histogram list tree
items.

RTFM of http://root.cern.ch/root/htmldoc/TGListTree.html#TGListTree:description shows
how to correctly position the popup menu without kludging the event handler. Commited.

> The other problem is multiple selection of histograms.

Short answer: Multiple selection of list tree items cannot be done. The code in
TGListTree::HandleButton(Event_t *event) explicitely enforces single-selection by
always unconditionally unselecting all items. I will have to bring this up with the
ROOT team.

K.O.

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.

To set the x-axis limits, right click anywhere on a histogram frame and choose
"XaxisLimits" from the popup context menu.  This brings up a dialog box where
you can enter the xmin and xmax values. Click "OK" and all pads within the
currently selected canvas will be redrawn with that x-axis scale.  To reset all
histograms so the x-axes are unzoomed, click "Unzoom".

Every overlayed histogram on a currently drawn histogram, will be drawn in a
different color (up to the max number of colors).

When choosing a new pad division for a canvas (from the "Zones" menu), all
currently drawn histograms on that canvas will be redrawn in the new zones. If
there are fewer pads in the new configuration, the extra histograms are not
drawn.  Overlays (with their color) and x-axis scaling are preserved in the new
configuration.

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.
