Text Object

Level Advance [2017-11-19 19:46:19] - by hillzx

Creating a Text object is quite easy, by writing the following 5 lines of code:

// text1 is the name of the object
// Corner is a corner variable
// XPos is the X coordinate
// YPos is the Y coordinate
// Message is written content
// TextSize is a big letter
// TextColor is the color of the post

extern int Corner=0;
extern int XPos=0;
extern int YPos=0;
extern string Message="Halo percobaan";
extern int TextSize=14;
extern color TextColor=White;

ObjectCreate("text1",OBJ_LABEL,0,0,0,0,0);
ObjectSet("text1",OBJPROP_CORNER,Corner);
ObjectSet("text1",OBJPROP_XDISTANCE,XPos);
ObjectSet("text1",OBJPROP_YDISTANCE,YPos);
ObjectSetText("text1",Message,TextSize,"Verdana",TextColor);

OK, here's the formula:

  {

   return(rates_total);

void TulisText(){
   ObjectCreate("text1",OBJ_LABEL,0,0,0,0,0);
   ObjectSet("text1",OBJPROP_CORNER,Corner);
   ObjectSet("text1",OBJPROP_XDISTANCE,XPos);
   ObjectSet("text1",OBJPROP_YDISTANCE,YPos);
   ObjectSetText("text1",Message,TextSize,"Verdana",TextColor);
}

void DeleteObjects()
{
  for (int i = ObjectsTotal() - 1; i > -1; i--)
  {
   if (StringFind(ObjectName(i), "text") >= 0) ObjectDelete(ObjectName(i));
  }
}

The result after the indicator is installed will appear in the top left corner, because of all variables set extern that means the variable can be changed from Inputs Tab.
