how to change lines in "Comment()"

Hi, everyone,

I want to write comments in the chart window. I wonder if anyone could tell me how to change lines in the comments? For example, I want to write total1, total2 and total3 in the window in 3 lines, but the following code write them in a single line.

Comment(" total1=", total1, " total2=", total2, " total3= ",total3);

How should I code it?

Many thanks!

insert a slash n
x + "backslash n" + y etc
the real backslash
editor takes it out of here

Many thanks!

One more question, is it possible write something at the bottom of the chart window? or control the position of the words?

1) A quick and dirty way is to place lots of "slash n"s ahead of the text,
2) Better way is to use ObjectCreate

Here is part of the code:
ObjectCreate(myObject, OBJ_LABEL, 0, 0, 0);
ObjectSet(myObject, OBJPROP_CORNER, 3); // Upper Left=0; Upper Right=1; Lower Left=2; Lower Right=3
ObjectSet(myObject, OBJPROP_YDISTANCE, yPos);
ObjectSet(myObject, OBJPROP_XDISTANCE, 3);
ObjectSetText(myObject, s, 10, "Arial", LabelColor);

Use 2 backslashes and one will survive the editor

Comment(" total1=", total1, " \ntotal2=", total2, " \ntotal3= ",total3);

PHP Code
Comment(" total1=", total1, " \ntotal2=", total2, " \ntotal3= ",total3);

This function will do that:

PHP Code
void PrintText(string sText, string sObjId, int iXPos, int iYPos, 
                                     int iCorner, color cTxtColor=LightBlue) { 
  // Create Text Object
  if (ObjectFind(sObjId)<0 ) {
    ObjectCreate(sObjId, OBJ_LABEL, 0, 0, 0, 0, 0);
    ObjectSet(sObjId, OBJPROP_CORNER, iCorner);
    ObjectSet(sObjId, OBJPROP_XDISTANCE, iXPos);
    ObjectSet(sObjId, OBJPROP_YDISTANCE, iYPos);
    ObjectSet(sObjId, OBJPROP_BACK, false);
  }
  // Move and write text
  ObjectMove(sObjId, 0, iXPos, iYPos); 
  ObjectSetText(sObjId, sText, 9, "Courier New", cTxtColor);
}
Each text object created should have a unique name and when exiting the indicator/EA, the objects created should be deleted. A good practice is to prepend the indicator name to the ObjectID. Doing so will reduce the possibly of the indicator objects created conflicting with the objects of other indicators.

Sample Call:
PHP Code
PrintText("Range: "+Range, "MyIndicator_Range1", 5, 15, 0, LightBlue);
And the deinit() function to erase all 'MyIndicator' Objects:
PHP Code
int deinit()  {
  // Clear graphical objects
  for(int i=ObjectsTotal()-1; i>-1; i--)
   if (StringFind(ObjectName(i),"MyIndicator")>=0) ObjectDelete(ObjectName(i));
  return(0);
}
Pew. All this just to write one string of text. Go mql4! Still, it's 100% better than the proprietary java platforms that have no support for custom indicators and EAs.

Also the text is aligned from the corner. Each corner has the coordinates (0,0). So moving the text to the various corners will have unintended alignment consequences which one may have to adjust for.

Many thanks! It seems the words (characters/width) allowed by the function is quite narrow. I can write less than 70 characters using the function. How can I write more words?

Many thanks again!

Seems to be a limit in ObjectSetText(). Write 2 strings?
