<H2>DESCRIPTION</H2><PRE>
|
|
These functions make it possible to set hook functions to
|
|
be called at various points in the automatic processing of
|
|
input event codes by <STRONG>menu_driver</STRONG>.
|
|
|
|
The function <STRONG>set_item_init</STRONG> sets a hook to be called at
|
|
menu-post time and each time the selected item changes
|
|
(after the change). <STRONG>item_init</STRONG> returns the current item
|
|
init hook, if any (<STRONG>NULL</STRONG> if there is no such hook).
|
|
|
|
The function <STRONG>set_item_term</STRONG> sets a hook to be called at
|
|
menu-unpost time and each time the selected item changes
|
|
(before the change). <STRONG>item_term</STRONG> returns the current item
|
|
term hook, if any (<STRONG>NULL</STRONG> if there is no such hook).
|
|
|
|
The function <STRONG>set_menu_init</STRONG> sets a hook to be called at
|
|
menu-post time and just after the top row on the menu
|
|
changes once it is posted. <STRONG>menu_init</STRONG> returns the current
|
|
menu init hook, if any (<STRONG>NULL</STRONG> if there is no such hook).
|
|
|
|
The function <STRONG>set_menu_term</STRONG> sets a hook to be called at
|
|
menu-unpost time and just before the top row on the menu
|
|
changes once it is posted. <STRONG>menu_term</STRONG> returns the current
|
|
menu term hook, if any (<STRONG>NULL</STRONG> if there is no such hook).

|
|
<H2>RETURN VALUE</H2><PRE>
|
|

|
|
routines return one of the following:
|
|
|
|
<STRONG>E_OK</STRONG> The routine succeeded.
|
|
|
|
<STRONG>E_SYSTEM_ERROR</STRONG>
|
|
