CHAPTER 23. PRESENTATION TYPES

The class that represents the default view that is used when computing pointer documentation.
It is a subclass of textual-view.

=> +textual-view+ [Constant]
=> +textual-menu-view+ [Constant]
=> +textual-dialog-view+ [Constant]
=> +gadget-view+ [Constant]
=> +gadget-menu-view+ [Constant]
=> +gadget-dialog-view+ [Constant]
=> +pointer-documentation-view+ [Constant]
These are objects of class textual-view, textual-menu-view, textual-dialog-view, gadget-
view, gadget-menu-view, gadget-dialog-view, and pointer-documentation-view, respec-
tively.

=> stream-default-view stream [Generic Function]
Returns the default view for the extended stream stream. accept and present get the default
value for the view argument from this. All extended input and output streams must implement
a method for this generic function.

=> (setf stream-default-view) view stream [Generic Function]
Changes the default view for stream to the view view. All extended input and output streams
must implement a method for this generic function.

23.7 Presentation Translators

CLIM provides a mechanism for translating between types. In other words, within an input
context for presentation type A the translator mechanism allows a programmer to define a
translation from presentations of some other type B to objects that are of type A.

Note that the exact representation of a presentation translator has been left explicitly unspecified.

23.7.1 Defining Presentation Translators

=> define-presentation-translator name (from-type to-type command-table &key gesture tester
tester-definitive documentation pointer-documentation menu priority) arglist &body body [Macro]
Defines a presentation translator named name that translates from objects of type from-type
to objects of type to-type. from-type and to-type are presentation type specifiers, but must
not include any presentation type options. from-type and to-type may be presentation type
abbreviations.

command-table is a command table designator. The translator created by this invocation of
