The following example creates a menu with three items and then uses _DisposeItem( ) to remove two of the items.
SET LIBRARY TO DISPITEM
#include <pro_ext.h>
FAR DisposeItemEx(ParamBlk FAR *parm)
{
MENUID menuId;
ITEMID itemId;
Point loc;
menuId = _GetNewMenuId();
_NewMenu(MPOPUP, menuId);
itemId = _GetNewItemId(menuId);
_NewItem(menuId, itemId, -2, "\\<1st item");
itemId = _GetNewItemId(menuId);
_NewItem(menuId, itemId, -2, "\\<2nd item");
itemId = _GetNewItemId(menuId);
_NewItem(menuId, itemId, -2, "\\<3rd item");
loc.v = 10; loc.h = 20;
_SetMenuPoint(menuId, loc);
_ActivateMenu(menuId);
_Execute("WAIT WINDOW 'Menu has three items'");
_DisposeItem(menuId, _GetItemId(menuId, 1));
_Execute("WAIT WINDOW 'Menu has two items'");
_DisposeItem(menuId, _GetItemId(menuId, 0));
_Execute("WAIT WINDOW 'Menu has one item'");
_DisposeMenu(menuId);
}
FoxInfo myFoxInfo[] = {
{"ONLOAD", (FPFI) DisposeItemEx, CALLONLOAD, ""},
};
FoxTable _FoxTable = {
(FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
