Menu manager

[Mistrick]

Description

We need API for creating menus.
In amxx exists Old style menu and New menus.
I suggest create all in one.

enum Menu
{
	INVALID_MENU = -1
};

enum MenuStyle
{
	STYLE_ITEMS,
	STYLE_TEXT
}

enum MenuProps
{
	// def 7 like amxx
	MPROP_ITEMS_PER_PAGE,
	// def "\r#num#." like "1. item"
	// custom "\r[#num#]" like "[1] item"
	MPROP_NUMBER_FORMAT,
	// show/hide exit item
	MPROP_EXIT,
	// custom name for exit, back, next
	MPROP_EXIT_NAME,
	MPROP_NEXT_NAME,
	MPROP_BACK_NAME,
	// for hl, etc
	MPROP_NO_COLORS,
};

enum ItemStatus
{
	ITEM_ENABLED,
	ITEM_DISABLED
};


enum MenuItem
{
	MENU_EXIT = -3,
	MENU_NEXT = -2,
	MENU_BACK = -1
};

// typedef MenuHandler = function int (Menu menu, MenuAction action, int param1, int param2);

typeset MenuHandler
{
	// text style
	function void(
		Menu menu,
		int key,
		int player
	);

	// item style
	function void(
		Menu menu,
		MenuItem item,
		int player,
		any data
	);
};

typedef CallbackHandler = function ItemStatus (Menu menu, MenuItem item, int player);


methodmap Menu
{
	// param global if false then destroy after exit
	public native Menu(MenuHandler handler, MenuStyle style = STYLE_ITEMS, bool global = false);
	// param page only for STYLE_ITEMS
	public native void Show(int player, int time = -1, int page = 0);
	
	// only for STYLE_TEXT
	public native void AddText(const char text[]);
	public native void AddKeys(int keys);
	
	// only for STYLE_ITEMS
	public native void SetTitle(const char title[]);
	public native void AddItem(const char name[], any data = 0, CallbackHandler callback = 0);
	// for blank use AddText(0, "\n") or make "\n" by default instead ""
	// TODO: change native name
	public native void AddText(int slot = 0, const char text[] = "");
	public native void SetProp(MenuProps prop, any ...);
	property int Items {
		public native get();
    }
}

// close any active menu
native void CloseMenu(int player);

How do we replicate the issue?

Create manager?

Expected behavior (i.e. solution)
