======================================================================= Changelog: 12/23/15 - v0.8 - Fixed Issue #2 (VarIntVal constructor was checking _val before it was set) - Made shared_ptr explicitly use std::tr1 namespace - Cleanup in VarTypesFactory - Added import/export options - More coherent use of shared_ptr - Added VarAny wrapper - Added runtime loader interface, for at-runtime loading of vartype .so's (optional feature) - Changed emit to Q_EMIT - Integrated example into CMakeLists.txt and removed .pro build file. 06/10/11 - v0.7 - Changed to shared_ptr model for all VarTypes. - VarTypes now requires the tr1 C++ extensions. 10/25/10 - v0.6 - Re-licensed from GPL to LGPL, so VarTypes can now be used in commercial applications. - Added CMake files for building shared library. - Removed directory prefixes from include directives to be compliant with cmake's library installation. - Qt is now a requirement for compilation. Removed all VDATA_NO_QT statements. 12/04/09 - v0.5 - The VarTypes system now lives in the "VarTypes" namespace. - renamed "VarData" class to "VarType" - restructured code to separate between a full "VarType" and its containing raw data value "VarVal", allowing better integration in projects where pure high-performance data-types are required without the VarData overhead (caused by e.g. mutexes and the string-label + render-flags associated with each VarData type). - VarTypes are now template-instanciated through "VarTypeTemplate" - added the VarTypesFactory class, allowing easier, single-point creation of custom user-defined VarTypes by inheriting the VarTypesFactory. - added the clone() and cloneDeep() operators for all VarVals. - added binary string store load interface. - renamed all enumerations using more reasonable conventions - changed "renderFlags" to just "Flags" since they control much more than just render behavior. - changed string handling in XML i/o for code safety improvements - compilation should now work in windows
4/16/09 - v0.4 - added multi-item selection type - added VarNotifier class to catch change-events for entire sub-trees - fixed several bugs - improved visualization: - used persistent editors where applicable - bools now based on checkboxes - moves delegate functionality into respective type classes 10/31/08 - v0.3 - added string enums, fixed various performance bugs - added doxygen-style headers to files and classes 11/13/07 - v0.2 - basic thread-safety added - added VarQWidget and VarTrigger (buttons) types - added persistent editor flag - added no-load and no-save flags 9/27/07 - v0.1 - first release

About: VarTypes is a feature-rich, object-oriented framework for managing variables in C++ / QT4.

Features: VarTypes allows hierarchical organization, thread-safety, load/store to/from xml, QT4-based signals, QT4-based model/view visualization.

          VarTypes aims to make it easy for application developers to
          integrate automatic settings loading/storage, even for complex
          trees of settings. At the same time it allows a user to comfortably
          edit such settings in real-time without any risks of concurrency
          problems.

          Among supported base types are int, bool, double, string,
          string enumerations, lists, binary data, and triggers.
          More complex types can be added easily by inheriting the
          VarData base-class.

Requires: cmake, Qt >=4.5, C++ tr1 libraries (automatically supplied by many modern compilers).

Usage: The VarTypes library can be built by running: 1) make 2) sudo make install Note that cmake is required to build it.

          An example including the QT4 GUI is located in the example/
          directory. It is built automatically along with the library
          (but is not installed as part of the install command).
          
          To run the example:
          
          build/vartype_example

          All the interesting code on how to construct a vartree and
          GUI is located in example/src/mainwindow.cpp
          

Files: vartypes/primitives/ includes all basic vartype-datastructures

          vartypes/VarTypes.h
              is the main header to include to make use of the system

          vartypes/primitives/VarType.h
              is the base-class of all vartypes

          vartypes/gui/
              includes all GUI related QT widgets.

         vartypes/xml/
              includes the XML file parser/writer which was written by
              and is copyrighted by Frank Vanden Berghen.
