The EiffelVision figure cluster can be considered a high-level way of drawing on an [[ref:libraries/vision2/reference/ev_drawable_chart|EV_DRAWABLE]] descendant. Here are some advantages:
|
||||
* The model is separated from the representation by using projectors that take a world of figures and project it to any device, not just a drawing area.
|
||||
* Instead of drawing with static API's like draw_line, real figure objects are used that can move, change color or morph.

EiffelVision 2 is a platform independent Graphical User Interface (GUI) library that allows easy, simultaneous development of Windowed applications for both Windows & Unix based platforms. Heavily relying on EiffelBase library, EiffelVision 2 has been designed primarily with ease of use in mind. By reusing EiffelBase structures, existing, as well as new Eiffel users will find EiffelVision to be surprising intuitive and easy to use. In no time, users will be producing good-looking Windowed application skeletons, of which will run on a multitude of platforms with no manipulation of code.
|
||||
The EiffelVision 2 library includes the following interface clusters:
|
||||
* A [[Kernel| kernel]] cluster that includes classes that are key to a Vision2 application. The main class being [[ref:libraries/vision2/reference/ev_application_chart| EV_APPLICATION]] which is the main entry point of all Vision2 applications.

The kernel cluster contains classes that provide functionality that are common to most Windowed application. These classes are considered the core, or kernel of any Vision2 application. The most important of these classes is [[ref:libraries/vision2/reference/ev_application_chart|EV_APPLICATION]] . This is used to initialize the graphical toolkit and event loop of your Vision2 application. Kernel also includes classes such as [[ref:libraries/vision2/reference/ev_timeout_chart| EV_TIMEOUT]] that calls procedures (via agents) at a set interval, and [[ref:libraries/vision2/reference/ev_color_chart| EV_COLOR]] which is used for coloring widgets and items. To start programming with Vision2, you first have to correctly initialize [[ref:libraries/vision2/reference/ev_application_chart|EV_APPLICATION]] .

Pick and drop is a mechanism which allows data to be transported from a '''source''' object to a '''target'''. Any Vision2 object inheriting [[ref:libraries/vision2/reference/ev_pick_and_dropable_chart|EV_PICK_AND_DROPABLE]] can be used to transport or receive data.
