CChartObjectRectLabel question

Note: If this post is duplicated, sorry.  I'm pc crashed while I was doing it.

Isn't an object of this type supposed to support text in it?  My code draws the box just fine.  But no text shows up inside.  I'm pretty sure I'm missing something.  Anyone know?

#property strict
#include <ChartObjects\ChartObjectsTxtControls.mqh>
CChartObjectRectLabel rectLabel;

int OnInit()
  {
   return(INIT_SUCCEEDED);
  }

void OnDeinit(const int reason)
  {

  }

void OnTick()
  {
   rectLabel.Create(0,"rlabel",0,75,75,100,100);
   rectLabel.BackColor(clrBlack);
   rectLabel.Hidden(false);
   rectLabel.SetString(OBJPROP_TEXT,"My Box!");
   rectLabel.Color(clrYellow);
  }
