o The AdaSoft Graphical User Interface (GUI) is designed for the development
of intercative graphics applications in Ada. With it, sophisticated user
interfaces can be built that operate entirely in graphics mode. Programmers
access to the facilities of the AdaSoft GUI is via the Application
Programming Interface (API) which consists of the Window API, the Menu API,
and the Canvas API.
o Window API
Window management is performed by manipulating Window Objects with cursor
keys or a mouse. A window may be either a text or a graphics class window.
o Menu API
The Menu API supports the creation and display of Menu Objects. Three
different types of menus - Pop-up Menus, Bar Menus, and Pull-down Menus -
are supported.
o Canvas API
Any number of logical drawing surfaces, or Canvas Objects, may be created
by an application program. Graphical Objects are drawn and manipulated on
a canvas. A Canvas is made visible by associating it with a graphics class
window. The window may be placed anywhere on the canvas and the contents of
the window scaled to any size. Using scroll bars and 'zoom' icons, the
window may be moved over the canvas either vertically or horizontally and
the visible contents of the canvas dynamically rescaled.
