** Dec 02, 2008**
Implemented the capability for zooming cell contents.

Dynamic entries under the Windows menu are now checkable and exclusive.

** Nov 30, 2008**
Fixed a bug in the navigation of huge datasets. Now displayed data is properly
updated when a slider drag ends and when the table is wheeled.

** Nov 13, 2008 **
Navigation of huge datasets is now fully implemented. Every navigation
device (vertical scrollbar, keyboard and mouse wheel) seems to work fine and
to update displayed data when a buffer fault occurs.

** Nov 04, 2008 **
Navigability of huge datasets has been enhanced. The selected cell is now
properly updated when a buffer fault occurs. It means that navigating the
table with the keyboard works fine now.

** Oct 31, 2008 **
Huge datasets can be displayed and navigated. Several things remain to be
done (usability enhancements) but the feature seems usable and stable.

** Oct 24, 2008 **
Opening files by dropping their icons in the databases tree panel is fully
implemented.

Some annoying problems that arised when nodes were moved around in the
databases tree panel have been fixed.

I've started to implement the support for huge datasets.

Opening files by dropping their icons in the databases tree panel has been
partially implemented.

Fixed a couple of bugs in the Properties dialog: data types are correctly
shown now.

In-place renaming of nodes has been debugged.

Fixed a little problem with groups expansion in the tree view pane that was
rather annoying: now pasting a node (or creating a new group) expands the
parent group if it was closed. So user can see that the node has really been
added.

** Oct 22, 2008 **
More progresses in the datasets displaying:
- the workspace and the tree of databases are synchronized now: if a leaf
with a view is selected in the tree then the view becomes active in the
workspace. And viceversa, if a view is activated in the workspace its leaf
is automatically selected in the tree
- when a node with views is overwritten (because a group has been created, a
node has been renamed or a node has been pasted/dropped) the views are
closed
- the drag and drop behavior has been debugged

** Oct 21, 2008 **
Fixed a bug in the application quitting process: the temporary database
wasn't properly deleted.

** Oct 20, 2008 **
The Windows menu has been reimplemented.

** Oct 19, 2008 **
Datasets can now be displayed in the workspace. Still importants things
remain to be done, mainly to add support for quickly navigate huge datasets.

** Oct 17, 2008 **
The buffer.py module has been refactored and modified.

** Oct 16, 2008 **
Fixed a bug in the node rename and file save as operations. A node/file
cannot overwrite itself.

** Oct 13, 2008 **
Fixed a subtle bug in the code for renaming nodes.

Fixed a bug in the dialog for entering the name of a node when a group is
being created or a node is being renamed: empty strings are not valid names
now :-)

** Oct 11, 2008 **
The code for renaming nodes has been refactored. Affected modules are
vtapp.py, utils.py, inputNodeName.py and renameDlg.py.

The setup.py has been updated.

** Sep 26, 2008 **
Fixed some minor bugs regarding the enabled/disabled state of toolbar buttons
and menu items.

Added new module inputNodeName.py. It is used instead of renameDlg.py for
creating groups and entering the initial name in renaming operations.

** Sep 25, 2008 **
The behavior of the Open Recent File submenu is now a little bit more user
friendly.

** Sep 24, 2008**
Fixed a bug in the file opening procedure. Files with no PyTables/HDF5
format are properly managed now.

Some code in the vtapp.py module has been reorganized to make it more
readable.

** Aug 02, 2008 **
Fixed a couple of bugs in the File menu:

* the Close All action wasn't enabled/disabled properly
* the Save As... action didn't work

** Jul 23, 2008 **
The porting of the nodeProperties subpackage has finished.

** Jul 21, 2008 **
Merged r1054 and r1055 from trunk. Every modified file has been merged
but VERSION.

** Jul 18, 2008 **
The nodeProperties subpackage is being ported. At the moment the GUI
part has been ported. Next step will be porting the code for attributes
validation.

** Jul 15, 2008 **
Fixed a nasty bug that crashed the application every time a node was
expanded in the tree viewer. The reported Qt4 error was:

QObject: Do not delete object during its event handling!

I've been unable to locate exactly where the bug was. Apparently it was
produced by a strange interaction between VTApp and VTGUI classes so
I've embedded VTGUI in VTApp and removed the vtgui.py module. It seems
to fix the bug.

** Jul 07, 2008 **
The porting of the nodeProperties subpackage has started.

A new module, nodeDoc.py, has been added. It is in charge of the
information collection about a given PyTables node. This module makes
unnecessary the following ones: nodeDoc.py, tableDoc.py, arrayDoc.py,
unimplementedDoc.py and groupDoc.py. All those modules have been
removed from the project.

** Jul 03, 2008 **
The behavior of the Preferences dialog has been tuned.

** Jul 01, 2008 **
The porting of the documentation browser has been done.

The behavior of the documentation browser has been tuned.

** Apr 07, 2008 **
Implemented Node --> Rename command with overwriting support.

** Apr 03, 2008 **
Fixed a bug in the algorithm for recovering last session. Now if a
given node doesn't exist then the application reports it and doesn't
crash.

Implemented Node --> New Group command with overwriting support.

** Apr 02, 2008 **
The overwriting feature has been implemented in the drag and drop of
nodes.

Splash screen readability improved.

Fixed a bug in DBDoc.pasteNode method of dbDoc.py module.

setup.py and Makefile.

Version number has changed to 2.0.

A note has been attached to the start of every source file of ViTables.
In this note it is specified how the ViTables program is licensed.

** Mar 27, 2008 **
Copyright statement of source files has been updated.

ViTables logo has changed: now it doesn't contain the Carabos logo.
I've done this because now ViTables is not developed by Carabos Coop.
V.. Instead it is a free software project maintained by myself.

The ViTables source code license has changed. From now on it has a
GPLv3 license.

** Mar 26, 2008 **
Creating a branche for porting ViTables to PyQt4.

Fixed a little problem in the drag and drop support of the tree of
databases model/view.

The treeEditor subpackage has been removed.

The functionality of the File menu has been implemented. Only
overwritting files during a File --> Save as... operation remains
unimplemented.

Fixed a couple of bugs in the tree of databases model:
- the close database operation didn't remove the node from the tree
view.
- when opening a database fails the returned value was no specified.

The configuration module has been rewritten.

Small changes introduced in several modules: the name of some
attributes has changed and some imports have been slightly modified.

** Mar 20, 2008 **
The vtgui.py module has been refactored and some small problems have
been fixed: the size of the toolbars icons, the WhatsThis action
setup, and the setup of the menu with entries for the toolbars.

The vtgui.py module porting is done. The result is a module much
shorter and clearer thant it was before.

** Mar 19, 2008 **
The porting of the vtgui.py module has started. It has been greatly
simplified.

The drag and drop behavior of the tree of databases view has been
debugged a little bit.

PyQt4.QtXXX libraries are now imported as QtCore and QtGui instead of
qtCore and qtGui. In addition a couple of modules have some minor
changes.

** Mar 18, 2008 **
Copy, cut, paste and delete operations have been implemented in the
tree of databases model. Overwriting has not been considered yet.

** Mar 05, 2008 **
Basic drag and drop of the tree of databases model/view works!
Nodes can be moved from one location to another (even in a different
file). Nodes that belong to files opened in read-only mode cannot be
dragged. Lazy population of the model works fine too.

** Mar 03, 2008 **
The basic model/view implementation for the tree of opened databases
is done. Databases can be opened and closed. The object tree of a
given database is populated in a lazy way so that performance is
guaranteed when opening files with a large number of nodes. Finally,
icons are tied to nodes in the tree view.

** Feb 29, 2008 **
Drag and drop support is being implemented.

** Feb 27, 2008 **
Added basic support for renaming nodes in-place.

** Feb 26, 2008 **
Added support for custom context menus to the tree of databases view.

Some modules have been changed in order to keep internal consistency.

Minor modifications made in several modules.

** Feb 22, 2008 **
The h5db subpackage has been updated. Calls to Qt3 methods have been
moved to Qt4 equivalent methods.

nodes subpackage has been updated. Calls to Qt3 methods has been
replaced by calls to Qt4 methods.

** Feb 20, 2008 **
createIcons function changed: removed a line that was commented out.

The nodes subpackage migration has started. Calls to Qt
functions/methods have been adapted to Qt4.

** Feb 18, 2008 **
The following modules have been ported:

* scripts/vitables
* vitables/utils.py
* vitables/vtsplash.py
* vitables/vtSite.py
* vitables/vtgui.py
This module has been split in two modules: logger class is defined
in a new module now.
* vitables/logger.py

The whole preferences subpackage has been ported:
* vitables/preferences/vtconfig.py
* vitables/preferences/preferences.py
* vitables/preferences/configException.py

The following tests have been ported:
* vitables/preferences/preferencesGUI.py
* tests/preferences/test_vtconfig.py
* tests/preferences/test_preferences.py

** Dec 16, 2007 **
The Spanish translation has been updated.

WhatsThis help texts and some About... texts have been reformatted in
order to improve the code readability.

** Dec 14, 2007 **
The previous bug fix in the editing of the TITLE system attribute was
incomplete. It has been corrected now (hopefuly).

** Dec 13, 2007 **
Fixed a bug in the editing of the TITLE system attribute (accents
raised errors).

Some trivial enhancements have been done.

The editing of user attributes has been improved. Overflow cases are
now properly detected and a ValueError is raised. Although this is not
the default behavior of numpy arrays (which are silently converted to
the apropriate dtype when an overflow occurs) it seems more adequated
for an end user application as ViTables.

** Nov 29, 2007**
Drag and drop of nodes has been debugged. Cut and paste has been improved.
I hope that editing nodes is now implemented in a quite robust way.

** Nov 28, 2007**
The behaviour of the documentation browser has been improved.
A couple of bugs have been fixed:
- canceling the Open File... command works fine now
- opening a new documentation browser doesn't give errors due to not found
documents
- trying to open a document that doesn't exist don't shows a blank page but a
page with the message 'Document Not found'

A mess due to the use of backslashes still happened on Windows platforms,
specially in the list of recent files and in the navigation browser history
and bookmarks. This problem has been hopefully solved.

The copy and paste operation has been enhanced. Now a node can be copied and
pasted in its parent group. The overwrite dialog is raised, giving you the
chance to rename the pasted node. If you decide to overwrite, the operation
fails (a PyTable exception is raised) because a node cannot be overwritten
by itself.

** Nov 27, 2007**
The template script that generates the Windows installer has been updated.
Now it takes care of the available translations.

Unittests have been updated.

The search method for locating the application settings has been improved on
Mac OS X platforms.

** Nov 26, 2007**
Spanish translation added.

A couple of minor problems have been fixed:
- the .vitables directory is not created on Mac OS X platforms anymore
- the message raised when a directory is dropped on the tree viewer is now
clearer

The User's Guide has been updated.

** Nov 23, 2007**
Displaying of objects in tables widgets has been enhanced. Now cell contents
are dynamically adapted to the available room. It means that how the content
of a given cell is displayed depends on the column width. As a consequence,
the displaying of multidimensional objects has been greatly improved.

Some changes aimed to improve the i18n have been done.

** Nov 21, 2007**
Fixed a bug in the creation of user attributes with dtype float32.

Errors raised during user attributes editing are displayed in the attributes
editing dialog, not in the logger. This make easier to user to realise that
an error has been raised.

** Nov 19, 2007**
The release version has been updated.

The User's Guide source has been updated.

The DocBrowser behavior has been enhanced. Opening a file for the very first
time in the DocBrowser uses the home directory as a working directory.
Before it used the installation directory which was ugly.

** Nov 02, 2007**
Fixed a bug in the access to VLArrays elements. The bug avoided the creation
of views for VLArrays.

VERSION has been updated in vtSite.py. This is required in order to run
properly on Mac OS X platforms because on these platforms the module is NOT
overwritten by setup.py.

The temporary database is not removed when quitting ViTables because on
Windows platforms a Permission denied error is raised.

**Oct 31, 2007**
Explicit support for addressing 64 bit space has been added. Now ViTables
can display tables with more than 2**32 rows with no problem.

A small bug has been fixed (hopefully) in the node paste operation: pasting
a node on an expanded group doesn't refresh the object tree i.e. the pasted
node is not visible.

The whole unittest directory has been updated/refactored/debugged.

I forgot to update tests/test_all.py in the previous commit :-(

Fixed a small bug in the File Save As... procedure. The file extension of
the new file was generated in a wrong way because the full filepath was used
to determine the extension. The right thing is to use the filename.

**Oct 30, 2007**
The Users' Guide has been updated.

A specific icons has been given to the toobar button in charge of opening
files so that users can appreciate that it can show a popup menu now.

Fixed a bug in File --> Close All and Query --> Delete All. Closing a set of
non selected nodes caused a wrong update of the QAction in charge of
closing all open files. Deleting a set of non selected filtered tables
caused a wrong update of the QAction in charge of deleting all filtered
tables.

Fixed a bug in the procedure used to close a database. A race condition has
been removed.

A new icon has been added.

Fixed a bug in the updating of query QActions. The bug couldn't be
appreciated by users because it happened when the application was about to
exit.

**Oct 26, 2007**
The VERSION file has been updated.

A new usability enhancement has been added. The Open button of the File
toolbar is able now to open the file of Recent files too.

**Oct 22, 2007**
Fixed a bug in the initial setup of the application.

Fixed a bug in the Properties dialog of empty groups.

Creating and renaming node operations have been made more robust.

Fixed a small problem of name qualification when accessing to a couple of
PyQt attributes.

**Oct 19, 2007**
Usability of Properties dialog has been improved by fixing the visual
behavior of attributes editing.

The format given to catched errors has changed again. Now the readability of
Syntax Errors is better.

In the Filter Table dialog ValueErrors are explicitely catched now.

**Oct 18, 2007**
Some classes still were instantiated via apply(qt.QSomeWidget.__init__,
(self,args)). Now qt.QSomeWidget.__init__(self, args) is used.

The behavior of tables shown in the Properties dialog has been improved.
Tables have been resized so that they occupy all the available horizontal
space leaving no (anoying) gaps.

**Oct 17, 2007**
Fixed a small bug in the console that produced a wrong color update in some
situations.

Wild imports have been completely removed.

The examples directory has been updated.

**Oct 16, 2007**
The management of application preferences and configuration has been
improved. The code has been simplified and a small bug has been fixed.

Fixed a bug in the Preferences dialog that made the Cancel button useless.

Some error and warning messages have been changed in order to ensure that all
of them have a consistent format.

**Oct 15, 2007**
The resize mode of the Tree Viewer widget has been fixed so that the widget's
header resizes properly its sections when the widget is resized.

A subtle bug has been fixed in the setup of the default configuration of the
application.

**Oct 11, 2007**
Some logger messatges have been changed in order to make them
self-explanatories.

The installer template script has been modified. The name of the installer
includes the kind of license now.

Fixed a small bug in the File Save As... command. It avoided open files
overwriting on Windows platforms.

The format used for display catched exceptions has changed. Now it is more
readable (although provides less information).

**Oct 10, 2007**
The format of docstrings has been updated. Now every docstring has a
restructured text format.

Docstrings of every module have been updated. In particular the updated
sections are those that listed the names of classes, methods, functions and
global variables contained in the modules.

Code for moving a node from one location to a different one has been changed
in order to improve the performance.

**Oct 04, 2007**
Fixed a bug in the paste node procedure.

**Oct 03, 2007**
The behavior of the Query results node of the tree view has been setup
accordingly to its aim.

A subtle bug has been fixed in the dbView.py module. When dealing with
nodepaths os.path.join should be avoided in favour of tables.utils.joinPath.
The reason: in Windows platforms os.path.join can produce paths with a mix of
slashes and backslashes.

A small bug in the template installer script has been fixed. The uninstaller
didn't remove completely the ViTables entry from the Start menu.

Fixed a bug in the opening file process. When the open file dialog was
called for the first time (i.e. application startup) and the dialog was
cancelled then later calls of this dialog were unusable.

The procedure for saving a file with a different name has been slightly
changed to avoid a nasty HDF5 error. The error was raised when the new file
name was filename (with no extension) and a filename.h5 file already existed.

**Oct 02, 2007**
As no evaluation versions are going to be distributed the dbManager template
is not needed now. That's why it has been renamed to dbManager.py

Unneeded and obsolete files have been removed.

A small bug has been fixed in vitables/nodes/leafView.py. The bug was raised
by a bug in the underlying PyTables 2.0.1

The ViTables configuration has been updated. The Startup option `start in
current directory` is now `start in home directory` to avoid opening
unexpected directories in Windows and Mac OS X when ViTables is launched by
double clicking its desktop icon.

Fixed a small bug that prevented to start ViTables in the home directory
(when configured to do it) in Windows platforms.

The template script for generating installers has been modified to add more
items to the Start menu: links to documentation (in both PDF and HTML4
formats) and to the examples directory.

**Oct 01, 2007**
The users' guide has been updated.

A check has been added to several methods in vtapp.py, to ensure that
filepaths do not contain backslashes because they produce a real mess in the
Windows registry and the list of recent files.

**Sep 30, 2007**
Added a button for group creation to the Node toolbar.

**Sep 29, 2007**
Fixed a bug in the drag and drop of a node from a read-only file to a
read-write one.

**Sep 28, 2007**
QActions updating and synchronizating panels strikes back!
The last approache has been discarded because it didn't encompass every
possible case. The new approache seems to work better and it is simpler.

Fixed a bug that prevented empty nodes to be added to the object tree when
the tree was expanded.

Fixed a bug in the creation of new groups. Now the new group can overwrite
any node with the same name placed in its parent group. Before only groups
could be overwriten.

**Sep 27, 2007**
The Help Browser history and bookmarks are now stored in the configuration
file instead of in their own files.

Fixed a bug in the updating of the QActions state.

**Sep 26, 2007**
The list of recent files is now stored in the configuration file (or in the
Windows registry) instead of in its own file.

The last session is now stored in the configuration file (or in the
Windows registry) instead of in its own file.

unittests have been updated.

**Sep 25, 2007**
The configuration file lastdir, used to store the last opened directory has
been removed. Now this information is stored in the application configuration
file (or in the Windows registry).

**Sep 24, 2007**
Fixed a small bug in the recovering last session process.

**Sep 23, 2007**
Unittests have been updated.

**Sep 22, 2007**
Added a new usability improvement: the tree view pane and the workspace keep
now their selection state synchronized.

Several keyboard accelerators added.

**Sep 21, 2007**
A couple of small usability improvements has been added. The action
Node-->New group has a keyboard accelerator now.

**Sep 20, 2007**
The dialog raised when a node editing leads to a naming problem is now more
readable a.k.a useful.

Added permission to create groups under the Query results root node.

Fixed a bug that appeared when a node was moved from one file to a different
one.

Fixed a bug that appeared when a node was copied from one file and pasted
into a different one.

**Sep 18, 2007**
A small bug has been fixed in the renameDlg.py module.

Fixed a bug in the implementation of tables queries. The bug caused wrong
values to be displayed in the query indices field (if requested) when the
range of rows to be queried was other than (start=1, stop=n, step=1)..

**Sep 17, 2007**
A small bug has been fixed in the dbView.py module.

The unittests under tests/h5db have been updated.

**Sep 13, 2007**
The dialog raised when a naming problem appears has been enhanced. Now,
detailed information about the operation being executed is displayed and
buttons text is self-explanatory.

Fixed a small bug that affected the File Save as... operation.

Added support for overwriting nodes when a new group is being created.

Docstrings of dbMananger_template have been updated.

Fixed a small bug in renameDlg.py.

**Aug 09, 2007**
Fixed a serious bug in node deletions procedure.

New, clearer descriptions are used in the Properties dialog, in help texts
and in buttons text.

Unneeded messages are not passed to the logger anymore.

Management of filenames extensions has been improved.

The Query menu has been simplified.

The HelpBrowser toolbar layout has changed. It is clearer now.

**Aug 03, 2007**
All unittest modules have been refactored and debugged.

__init__.py files have been added to the tests directory and its
subdirectories.

test_all.py module has been added so that all unittests can be executed
easily.

testingHOWTO.txt has been updated and moved to the tests directory.

**Jul 31, 2007**
Unittest module test_query.py has been added.

The tables query implementation has been modified in order to make it more
suitable for testing it with unittests.

Fixed a bug that was hitting every module in the tests/nodes directory.

Unittests in the tests/preferences directory have been updated.

Unittest module root_package/test_commandLine.py updated.

**Jul 25, 2007**
Updated Mac packaging instructions to avoid linking sip/PyQt against wrong
Python.

**Jul 24, 2007**

INSTALL.txt and ChangeLog.txt have been updated.

VTApp.slotHelpAbout method changed. The info displayed in the About tab has
been updated.

Support for VLArrays has been enhanced. VLArrays with pseudo-atom of kind
vlunicode are now supported.

Module zoomCell.py has been updated accordingly to the recoded cell
formatting methods of utils.py

**Jul 23, 2007**

Use a `make.sh` script instead of `make` to build Mac OS X DMG images.
The process is not complete yet, since the license is not shown on opening
the DMG image. That's why the `SLA.*` files are still in place.

Makefile_windows and the template NSIS installer script have been updated.
Now they take care of the LICENSE.html file.

Makefile for unix has been simplified.

Added RTF readme to DMG image with important details for Mac OS X.

Removed the files for the Mac OS X DMG resource fork.

The license file in the DMG root is enough and easier to place. ;)

**June 20, 2007**
The mingwm10.dll library must be included in the installed ViTables because
qt and pyqt have been compiled dinamically with the MinGW compiler. The
Makefile mswindows/Makefile_windows and the template NSIS script
mswindows/vitables.nsi.in have been modified to take care of this dependency.

**June 15, 2007**

The methods for iterating over tree views have been refactored.

The mechanism for querying tables has been refactored and reorganized. Some
modules have moved to different locations, some methods have moved to

has been moved to other modules. The xxxEditor modules have been removed from
the project.

**May 12, 2007**
Fixed an annoying bug that produced lots of error messages when a new

Several internal operations have been simplified. The code of the whole
application is now clearer.

**May 11, 2007**
The utils.py module has changed. The function getNode has been moved to

been fixed for renaming and dropping operations. Some minor changes have
been done to descendants of NodeDoc class.

**Apr 23, 2007**
The queries management has been enhanced in several ways. On the one hand
performance of the filling of the result table has been increased when a
column for selected indices is required by user. On the other hand usability
of the query dialog has been improved in some aspects.

However there was a LeavesManager.closeGroup method designed for closing
every opened view under the selected group when the Close view action was
launched.

- the icons dictionary was recreated every time an icon was required by the
application. It caused the openRecentFile action not to work at all. On the

Properties dialogs.

The attributes editing stuff have been refactored and simplified.

**Mar 27, 2007**
The editing code of the TITLE system attribute has been simplified.

included anymore in the ViTables installer for Windows. Instead numpy will
be included so the numarray license has been substituted by the numpy one in
the 3rd_party_licenses directory.
