We are proud to announce that version 1.99.1 of pygtkmvc has been released. Project homepage: <http://apps.sourceforge.net/trac/pygtkmvc/wiki> Download: <http://sourceforge.net/projects/pygtkmvc/> ============== About pygtkmvc ============== pygtkmvc is a fully Python-based implementation of the Model-View-Controller (MVC) and Observer patterns for the PyGTK2 toolkit. MVC is a pattern that can be successfully used to design and develop well structured GUI applications. The MVC pattern basically helps in separating semantics and data of the application, from their representation. The Observer pattern helps to weaken dependencies among parts that should be separated, but need to be connected each other. pygtkmvc provides a powerful and still simple infrastructure to help designing and implement GUI applications based on the MVC and Observer patterns. The framework has been designed to be: * Essential and small, it does only what it was designed for. * Not an external dependency for your application: it fits in 200KB and can be released along with it. * Easy to understand and to use; fully documented. * Portable: straightly runs under many platforms. License: LGPL ********************************************************************** * Dec 30 2010 * ********************************************************************** Released version 1.99.1 This is a release that keeps compatibility with previous version 1.99.0. However, some features provided in 1.99.0 are deprecated in 1.99.1. This version goes in the direction of stabilizing the API and making the code more robust. Many bugs were fixed, and a new, clean API is now provided for defining notification methods in observers, and logical observable properties in models. The documentation has been updated and extended to reflect all changes, and a complete Library Reference is now available. Furthermore, the documentation now uses Sphinx instead of Latex to generate both pdf and html documentation formats. Last but not the least, the team grew up! * New - Models now feature Logical Observable Properties, along with already supported Concrete Observable Properties. - In Observers notification methods have all the same prototype, which make much cleaner the application code. - New mechanism to declare both dynamically and statically notification methods in Observers. - Auto-adapt of FileChooserButton, ComboBox and Adjustment - API to extend default adapter list - More widget types now correctly cast when adapted to unicode/int/float properties. - Enable RoUserClassAdapter to update the widget. It used to only do it when connecting, not on property changes. This makes the built-in support for gtk.Calendar work in both directions. - Controller's method adapt() allows auto-adaption even if the view does not have corresponding widgets for *all* properties in the model. - Adapters can optionally call prop_write *instead of* casting the value from the widget to the type of the old property value. This was the intended behaviour all along. Default is still to call it after the cast. - Decorators for property setters/getters in models. The methods can now have arbitrary names and you are no longer limited to one property per method. * Changed - Name-based notification methods like `property_<name>_value_change` are still supported, but their usage is now discouraged. A new mechanism for declaring notifications is now available, and you should consider porting applications accordingly. - Decorator Observer.observes is now deprecated. A new mechanism for declaring notifications is now available, and you should consider porting applications accordingly. - Support GtkBuilder in addition to libglade, which is no longer required. This changed the signature of the View constructor. The two formats are not equivalent, as GTK cannot build only parts of a file. - Allow creation of adapters that act on spurious notifications. - Use less eval(codestring) This changed how adapters create observer functions. If you have adapter subclasses you will have to adjust them. - Misuse of the framework that used to exit your application can now be caught as exceptions. - Fewer warnings printed by the framework. Remember to increase the logging level during development. * Fixed - Assigning a tuple with length 3 to a property no longer raises - Pass the correct model when emitting notifications for an inherited signal. This changes how all property wrappers track their owners, but your code should not be affected. - Wrapped sequences lacked crucial special methods like len and iter. - Inspecting wrappers no longer omits the class name. - Various changes to make SQLObjectModel actually usable. - Wrapping more than one sequence class could cause the wrong methods to be called on all but the last instance created. This did not affect programs that only use the built-in list type. - Mutable instances that used to be assigned to properties would notify of their changes even after being replaced in the model. - No more errors from static container adapters you didn't create. - Multiple concurrent iterators on views no longer steal each other widgets.
