  • Article

Releases the specified menu and all its items and frees all memory associated with this menu.

void _DisposeMenu(MENUID menuid)
MENUID menuid;            /* Menu identifier. */

Remarks

_DisposeMenu( ) doesn't release any submenus that are associated with the menu.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.

Example

The following example calls _DisposeMenu( ) after the user chooses a menu item.

Visual FoxPro Code

SET LIBRARY TO DISPMENU

C Code

#include <pro_ext.h>

void putLong(long n)
{
   Value val;

   val.ev_type = 'I';
   val.ev_long = n;
   val.ev_width = 10;

   _PutValue(&val);
}

FAR onSelection(long menuId, long itemId)
{
   _PutStr("\nitemId = "); putLong(itemId);
   _DisposeMenu(menuId);
}

FAR activateMenu(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);
   _OnSelection(menuId, -1, onSelection);
}

FoxInfo myFoxInfo[] = {
   {"ONLOAD", (FPFI) activateMenu, CALLONLOAD, ""},
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
