Guidata

Since this version, `guidata` is compatible with PyQt4 API 1 *and* API 2.
Please read carefully the coding guidelines which have been recently added to
the documentation.

Possible API compatibility issues:

* Removed deprecated wrappers around QFileDialog's static methods (use the wrappers provided by `guidata.qt.compat` instead):
* getExistingDirectory, getOpenFileName, getOpenFileNames, getSaveFileName

Bug fixes:

* qtwidgets.ShowFloatArrayWidget: fixed string float formatting issue (replaced %f by %g)
* Fixed compatiblity issues with PyQt v4.4 (Contributor: Carlos Pascual)
* Fixed missing 'child_title' attribute error with FileOpenItem, FilesOpenItem, FileSaveItem and DirectoryItem
* (Fixes Issue 8) disthelpers.add_modules was failing when vs2008=False

Other changes:

* added *this* changelog
* qtwidgets: removed ProgressPopUp dialog (it is now recommended to use QProgressDialog instead, which is pretty much identical)
* Replaced QScintilla by spyderlib (as a dependency for array editor, code editor (test launcher) and dict editor)
* qtwidgets.DockWidgetMixin: added method 'setup_dockwidget' to change dockwidget's features, location and allowed areas after class instantiation
* guidata.utils.utf8_to_unicode: translated error message in english
* Add support for 'int' in hdf5 save function
* guidata.dataset/Numeric items (FloatItem, IntItem): added option 'unit' (automatically add suffix ' (unit)' to label in edit mode and suffix ' unit' to value in read-only mode)
* Improved dataset __str__ method: code refactoring with read-only dataset widgets (DataItem: added methods 'format_string' and 'get_string_value', DataSet: added method 'to_string')
* Added coding guidelines to the documentation
* guidata.dataset.qtwidget: added specific widget (ShowBooleanWidget) for read-only display of bool items (text is striked out when value is False)
* guidata.hdf5io.Dset: added missing keyword argument 'optional' (same effect as parent class Attr)
* guidata.dataset.dataitems.IntItem objects: added support for sliders (fixes Issue 9) with option slider=True (see documentation)

Bug fixes:

* setup.py: added svg icons to data files
* gettext helpers were not working on Linux (Windows install pygettext was hardcoded)

Other changes:

* hdf5io: printing error messages in sys.stderr + added more infos when failing to load attribute

Bug fixes:

* setup.py: added svg icons to data files
* gettext helpers were not working on Linux (Windows install pygettext was hardcoded)
* DataSet/bugfix: comment/title options now override the DataSet class __doc__ attribute
* Added missing option 'basedir' for FilesOpenItem
* DirectoryItem: fixed missing child_title attribute bug
* For all DataSet GUI representation, the comment text is now word-wrapped
* Bugfix: recent versions of PyQt don't like the QApplication reference to be stored in modules (why is that?)
* Bugfix/tests: always keep a reference to the QApplication instance

Other changes:

* setup.py: added source archive download url
* Tests: now creating real temporary files and cleaning up at exit
* qtAllow a callback on LineEditWidget to notify about text changes (use set_prop("display", "callback", callback))
* qthelpers: provide wrapper for qt.getOpen/SaveFileName to work around win32 bug
* qtwidgets: optionally hide apply button in DataSetEditGroupBox
* added module guidata.qtwidgets (moved some generic widgets from guidata.qthelpers and from other external packages)
* qthelpers: added helper 'create_groupbox' (QGroupBox object creation)
* Array editor: updated code from Spyder's array editor (original code)
* Added package guidata.editors: contains editor widgets derived from Spyder editor widgets (array editor, dictionary editor, text editor)
* Array editor: added option to set row/col labels (resp. ylabels and xlabels)
* ButtonItem: changed callback arguments to*instance* (DataSet object), *value* (item value), *parent* (button's parent widget)
* editors.DictEditor.DictEditor: moved options from constructor to 'setup' method (like ArrayEditor's setup_and_check), added parent widget to constructor options
* Added DictItem type: simple button to edit a dictionary
* editors.DictEditor.DictEditor/bugfixes: added action "Insert" to context menu for an empty dictionary + fixed inline unicode editing (was showing the error message "Unable to assign data to item")
* guidata.qtwidgets: added 'DockableWidgetMixin' to fabricate any dockable QWidget class
* gettext helpers: added support for individual module translation (until now, only whole packages were supported)
* DataSetShowGroupBox/DataSetEditGroupBox: **kwargs may now be passed to the DataSet constructor
* disthelpers: added 'scipy.io' to supported modules (includes)
* Added new "value_callback" display property: this function is called when QLineEdit text has changed (item value is passed)
* Added option to pass a text formatting function in DataSetShowWidget
