How can i put objects in front all graphic elements ?

Hello.

I am creating some label objects, and need to put them in front all elements on the graphic window... but not works. Is there any specific property for that?

My code: 

void DrawBoxInformation(bool fixed=false){

   int y = 30;
   int x = 10;
   
   RectLabelCreate(0,"rectOrders",0,x,y,260,235,clrAliceBlue,BORDER_FLAT,CORNER_LEFT_UPPER,clrSteelBlue,STYLE_SOLID,2,false,fixed,true,0);

   RectLabelCreate(0,"rectTitle",0,x,y,260,32,clrSteelBlue,BORDER_FLAT,CORNER_LEFT_UPPER,clrSteelBlue,STYLE_SOLID,0,false,fixed,true,0);
   LabelCreate(0, "lblTitle", 0, x+5, 34, CORNER_LEFT_UPPER, "MULTISIGNAL EMITTER", "Arial Black", 12, clrWhite, 0.0, ANCHOR_LEFT_UPPER, false, fixed, true, 0);

}
