This variable holds the description of the current menubar. This may be
buffer-local. When the menubar is changed, the function
set-menubar-dirty-flag has to be called in order for the menubar
to be updated on the screen.
This variable holds the menubar description of the menubar that is
visible at startup. This is the value that
has at startup.
This function tells SXEmacs that the menubar widget has to be updated. Changes to the menubar will generally not be visible until this function is called.
The following convenience functions are provided for setting the
menubar. They are equivalent to doing the appropriate action to change
current-menubar, and then calling
Note that these functions copy their argument using
This function sets the default menubar to be menubar (see Menu Format). This is the menubar that will be visible in buffers that have not defined their own, buffer-local menubar.
This function sets the buffer-local menubar to be menubar. This does not change the menubar in any buffers other than the current one.
If true, the menubar will display keyboard equivalents. If false, only the command names will be displayed.
Function or functions called before a menubar menu is pulled down.
These functions are called with no arguments, and should interrogate and
modify the value of
current-menubar as desired.
The functions on this hook are invoked after the mouse goes down, but
before the menu is mapped, and may be used to activate, deactivate, add,
or delete items from the menus. However, using a filter (with the
:filter keyword in a menu description) is generally a more
efficient way of accomplishing the same thing, because the filter is
invoked only when the actual menu goes down. With a complex menu,
there can be a quite noticeable and sometimes aggravating delay if
all menu modification is implemented using the
These functions may return the symbol
t to assert that they have
made no changes to the menubar. If any other value is returned, the
menubar is recomputed. If
t is returned but the menubar has been
changed, then the changes may not show up right away. Returning
nil when the menubar has not changed is not so bad; more
computation will be done, but redisplay of the menubar will still be
Function or functions to call when a menu or dialog box is dismissed without a selection having been made.
