See 'man input' for documentation on the input system itself,<br /> 'man descriptors' for a general overview of the descriptor system, and<br /> 'man dialog' for documentation of dialog descriptors.<br /> <br /> As with dialog descriptors, the best header file to rely upon for picking<br /> up the menu item descriptor support is input.h.<br /> <br /> ===Public Fields===<br /> <br /> Menu_Item_Key: The text the user enters in order to select the menu item.<br /> Often a single letter, but not necessarily so.<br /> <br /> Menu_Item_Desc: The description of the menu item, as it will appear in<br /> the menu display constructed automatically by the menu dialog. Dialog<br /> colorization applies. In the case of a closure, received an extra second<br /> argument of the menu item descriptor.<br /> <br /> Menu_Item_Action: The action to take upon the menu item being selected.<br /> If none is specified, the dialog's Dialog_Action is used.<br /> <br /> Menu_Item_Access: Can be used to specify a closure that will determine<br /> whether a menu item is usable and will appear in the menu. The closure<br /> is passed the dialog descriptor as argument; if it returns True, the menu<br /> item is accessible, and if it returns False it is not.<br /> <br /> Menu_Item_Access_Message: A message that will be displayed if a user<br /> attempts to select the menu item when it cannot be used due to a<br /> Menu_Item_Access setting. Dialog colorization applies. If no<br /> Menu_Item_Access_Message is specified, the dialog will simply act as if<br /> the menu item were not in the menu.<br /> <br /> Menu_Item_Args: If specified as True, the menu item will accept an<br /> argument. For example, if the Menu_Item_Key were &quot;A&quot;, the user could<br /> type &quot;a xyz abc&quot;, and the menu item would be selected with &quot;xyz abc&quot; as<br /> its argument. The argument will be placed in the Dialog_Argument field<br /> of the dialog descriptor.<br /> <br /> Menu_Item_Extra: A space provided in the descriptor for user-defined<br /> data. Put anything in this field you want and use it any way you want.<br /> <br /> ===Internal Fields===<br /> <br /> Menu_Item_Tag: The tag for the descriptor system.<br /> <br /> ==See Also==<br /> <br /> [[man input|input(mechanisms)]], [[man dialog|dialog(descriptors)]], [[man descriptors|descriptors(mechanisms)]]</div>
