sm_menu_get*

Gets a menu's property 

int sm_menu_get_int(int mem_location, char *script, char *menu, int prop);
char *sm_menu_get_str(int mem_location, char *script, char *menu, int prop);

mem_location
The menu's memory location, one of the following constants: 
MNL_APPLIC
MNL_SCREEN
MNL_FIELD

script
The name of a memory-resident script that contains the menu. The script must already be loaded into memory at mem_location by sm_mnscript_load. If you supply NULL, Panther searches in the most recently loaded script in mem_location for the specified menu.

menu
The menu's name. If you supply NULL, Panther uses the first menu in script.

prop
The property to get. Table 5-10 lists the properties that you can get and their constants.

Returns

Description

sm_menu_get_int and sm_menu_get_str returns the current setting of the specified property. Use the _int variant for those properties that have an integer value—for example, MN_TEAR; use the _str variant for properties that take string values, such as MN_NAME and MN_TITLE.
