1.3 The CAPI model
Everything that the CAPI displays is contained within an interface (an instance of the class interface). When an interface is displayed a window appears containing all the menus and panes you have specified for it.
An interface can contain a number of menus which are collected together on a menu bar. Each menu on the menu bar can contain menu items or other menus. Items can be grouped together visually and functionally inside menu components. Menus, menu items, and menu components are, respectively, instances of the classes menu,menu-item, and menu-component.
Panes are window objects such as buttons and lists. They can be positioned anywhere in an interface. The CAPI provides many different kinds of pane class, among thempush-button,list-panel,editor-pane, andgraph-pane.
The positions of panes are controlled by a layout, which allows objects to be collected together and positioned either regularly (with instances of the classescolumn-layout orrow-layout) or arbitrarily using apinboard-layout. Layouts themselves can be laid out by other layouts -- for example, a row of buttons can be laid out above a list by placing both therow-layout and the list in acolumn-layout.
