CHAPTER 28. APPLICATION FRAMES

=> read-frame-command frame stream [Generic Function]
Reads a command from the stream stream on behalf of the frame frame. The returned value is
a command object.

The default method (on standard-application-frame) for read-frame-command simply calls
read-command, supplying frame's current command table as the command table.

=> execute-frame-command frame command [Generic Function]
Executes the command command on behalf of the frame frame. command is a command object,
that is, a cons of a command name and a list of the command's arguments.

The default method (on standard-application-frame) for execute-frame-command simply
applies the command-name of command to command-arguments of command.

=> command-enabled command-name frame [Generic Function]
Returns true if the command named by command-name is presently enabled in the frame frame,
otherwise returns false. If command-name is not accessible to the command table being used by
frame, command-enabled returns false.

Whether or not a particular command is currently enabled is stored independently for each
instance of an application frame; this status can vary between frames that share a single command
table.

=> (setf command-enabled) enabled command-name frame [Generic Function]
If enabled is false, this disables the use of the command named by command-name while in
the frame frame. Otherwise if enabled is true, the use of the command is enabled. After the
command has been enabled (or disabled), note-command-enabled (or note-command-disabled)
is invoked on the frame manager in order to update the appearance of the interface.

If command-name is not accessible to the command table being used by frame, using setf on
command-enabled does nothing.

=> display-command-menu frame stream &key command-table initial-spacing max-width max-height
n-rows n-columns (cell-align-x :left) (cell-align-y :top) [Generic Function]
Displays the menu associated with the specified command table on stream by calling display- command-table-menu. If command-table is not supplied, it defaults to (frame-command-tablestream). This function is generally used as the display function for panes that contain command
menus.

initial-spacing, max-width, max-height, n-rows, n-columns, cell-align-x, and cell-align-y are as for
formatting-item-list.
