output stream designator n. A Lisp object that is either an output stream, or the symbol
t, which is taken to mean *standard-output*.

pane n. A sheet or window that appears as the child of some other window or frame. A
composite pane can hold other panes; a leaf pane cannot.

parent n. The direct ancestor of a sheet or an output record.

path n. A region that has dimensionality 1, that is, has length.

patterning n. The process of creating a bounded rectangular arrangement of designs, like a
checkerboard. A pattern is a design created by this process.

pixmap n. An "off-screen window", that is, a sheet that can be used for graphical output, but
is not visible on any display device.

point n. 1. A region that has dimensionality 0, that is, has only a position. 2. A Lisp object
that represents a point.

pointer n. A physical device used for pointing, such as a mouse.

pointer documentation n. |Fill this in|

port n. An abstract connection to a display server that is responsible for managing host display
server resources and for processing input events received from the host display server.

position n. 1. A position on a plane, such as CLIM's abstract drawing plane. 2. Two real
number values x and y that represent a position.

presentation n. 1. An association between an object and a presentation type with some output
on a output recording stream. 2. A Lisp object that represents a presentation.

presentation tester n. A predicate that restricts the applicability of a presentation translator.

presentation translator n. A mapping from an object of one presentation type, an input
context, and a gesture to an object of another presentation type.

presentation type n. 1. A description of a class of presentations. 2. An extension to CLOS
that implements this.

presentation type specifier n. A Lisp object used to specify a presentation type.

programmer n. A person who writes application programs using CLIM.

protocol class n. An "abstract" class having no methods or slots that is used to indicate
that a class obeys a certain protocol. For example, all classes that inherit from the
bounding-rectangle class obey the bounding rectangle protocol.

rectangle n. 1. A four-sided polygon whose sides are parallel to the coordinate axes. 2. A Lisp
object that represents a rectangle.

redisplay n. See incremental redisplay.

region n. 1. A set of mathematical points in the plane; a mapping from an (x;y) pair into either
true or false (meaning member or not a member, respectively, of the region). In CLIM,
all regions include their boundaries (that is, they are closed) and have infinite resolution.
2. A Lisp object that represents a region.
