Here's the script.

Created an object. Assigned text.

Recognising the text itself and the size.

Why is the text itself recognized, but the size is not?

Why does it recognize the text but not the size?

I just checked.

Even the colour comes back correctly.

Why isn't the size? Is this some kind of taboo?

Until the text label is rendered, the size is unknown. What's not clear here?

Because the object has no time to render, you want too much...

string name="probe";
/////
void OnStart()
  {
   func();
   func();

   ObjectDelete(name);

  }
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void func()
  {
   ObjectCreate(0,name,OBJ_LABEL,0,0,0);
   ObjectSetString(0,name,OBJPROP_TEXT,name);

   Sleep(500);

   string text=ObjectGetString(0,name,OBJPROP_TEXT);

   int text_sizeX=int(ObjectGetInteger(0,name,OBJPROP_XSIZE));
   Alert(text," ",text_sizeX);

  }

When inserting a new message using SRC, the SRC text disappears.

When updating using/inserting SRC it's fine.

That's cool.

Now please help me to implement this in an indicator and make it work without ticks (on weekends).

Slawa:
As long as the text label is not rendered, the size is unknown. What is not clear here?

Do you have a solution to this issue in an indicator, without ticks?

And I've said it before. It's strange that you can get the text itself without rendering but not the size.

Thank you. But it's cumbersome to know the size of the text, to put it mildly.

Why is it possible to find out the text size without rendering but not the text size?

Why can we know the text itself without rendering but not its size?

Perhaps the text to be rendered is stored in a variable from which we retrieve it and you have to create an object of thousands of pixels to create the text.

And the code I gave you is just an example of a runtime implementation.
