Disable/Enable quad menu item using 3ds max sdk

[Anonymous]

I have added a menu item to the quad menu. how can I disable and enable this menu? 

IQuadMenuContext* pContext = (IQuadMenuContext*) GetCOREInterface()->GetMenuManager()->GetContext(kViewportQuad);

IMenu *pMenuInQuadMenu = NULL;
IQuadMenu *pQuadMenu = pContext->GetMenu(0);
pMenuInQuadMenu = pQuadMenu->GetMenu(0);

IMenuItem* pNewMenuItem = GetIMenuItem();
pNewMenuItem->SetActionItem( pAction );
pNewMenuItem->SetUseCustomTitle(true);
pNewMenuItem->SetTitle(L"Menu Item");
pMenuInQuadMenu->AddItem( pNewMenuItem,0 );

In your derived class of ActionItem, you can implement your own IsEnabled method as required.

For Example:

class MenuActionItem : public ActionItem

{

        BOOL IsEnabled()

        {

             return ( some_condition ) ? true : false ;

        }

}

This method will be called each time when you try to open a quad menu. So you can enable or disable your menu item here.
