@table @code
@item border-width
-The width in pixels of the window border.
+The width in pixels of the frame's border.
@item internal-border-width

+The distance in pixels between text (or fringe) and the frame's border.
@item vertical-scroll-bars
Whether the frame has scroll bars for vertical scrolling, and which side
@item line-spacing
Additional space to leave below each text line, in pixels (a positive
-integer). @cref{Line Height}, for more information.

@node Buffer Parameters
screen, in Emacs versions that did not support multiple frames. They
are semi-obsolete, but still work; they apply to the selected frame.
+@node Geometry
+@subsection Geometry
+
+ Here's how to examine the data in an X-style window geometry
+specification:
+
@defun x-parse-geometry geom
@cindex geometry specification
The function @code{x-parse-geometry} converts a standard X window
but @code{t} on MS-Windows.

+@node Drag and Drop
+@section Drag and Drop
+
+@vindex x-dnd-test-function
+@vindex x-dnd-known-types
+ When a user drags something from another application over Emacs, that other
+application expects Emacs to tell it if Emacs can handle the data that is
+dragged. The variable @code{x-dnd-test-function} is used by Emacs to determine
+what to reply. The default value is @code{x-dnd-default-test-function}
+which accepts drops if the type of the data to be dropped is present in
+@code{x-dnd-known-types}. You can customize @code{x-dnd-test-function} and/or
+@code{x-dnd-known-types} if you want Emacs to accept or reject drops based
+on some other criteria.
+
+@vindex x-dnd-types-alist
+ If you want to change the way Emacs handles drop of different types
+or add a new type, customize @code{x-dnd-types-alist}. This requires
+detailed knowledge of what types other applications use for drag and
+drop.
+
+@vindex dnd-protocol-alist
+ When an URL is dropped on Emacs it may be a file, but it may also be
+another URL type (ftp, http, etc.). Emacs first checks
+@code{dnd-protocol-alist} to determine what to do with the URL. If
+there is no match there and if @code{browse-url-browser-function} is
+an alist, Emacs looks for a match there. If no match is found the
+text for the URL is inserted. If you want to alter Emacs behavior,
+you can customize these variables.
