More About MT4gui

I want to include a box in the top right hand corner of my screen with 6 lines of data which change each time period (i.e. 1M,5M,30M etc).

I have seen some details about the mt4gui but not too much. I have extracted the following code from an example and the 'box' and TimeCurrent are displayed

The references to the font, font size and color seem to be ignored - am I missing something or not using correctly?

Can I use this process to create a multi-line display?

#import "mt4gui.dll"   
   int tbPutObject(int,string,int,int,int,int,string);
   int tbRemoveAll(int);
   int tbSetText(int,string,int,string);
   int tbSetBgColor(int,int);
   int tbSetTextColor(int,int);
#import
#include <libtrade.mqh>
#include <libvisual.mqh>
int l1;
int init()
  {    
      return(0);
  }
//+------------------------------------------------------------------+
int deinit()
  {
   return(0);
  }
//+------------------------------------------------------------------+
//| expert start function                                            |
//+------------------------------------------------------------------+
int start()
  {   int hwnd=WindowHandle(Symbol(),Period());
      tbRemoveAll(hwnd); ObjectsDeleteAll();
      l1=tbPutObject(hwnd,"text",850,100,200,20,TimeCurrent());   //from left, from top, width of box, height of box  
      tbSetBgColor(l1,Green); 
      tbSetTextColor(l1,Yellow);
      tbSetText(l1,"text",24,"Arial");
