Wrong font size in controls

[Daniel Cherry]

Hi,

A customer has reported that the fonts in this purchased product are the wrong size. I have no idea how this has occurred. I do not set the font size explicitly the code, I just let it use the defaults.

Are there any suggestions what may be causing this.

I have attached 2 pictures. Normal.jpg is what it should be and incorrect.jpg is my clients version.

Kind regards

Dan.

Your client uses a scale greater than 100%. MQL5 can not determine the scale, which is used by the system (without calling WinAPI).

Hi -thanks for the reply. Do you know which window setting he could be using to replicate this?

Kind regards Dan.

These settings must be in the "Screen".

While you don't have a function in mql5 to determine the Windows settings, it's perfectly doable to get it using TextGetSize and TextSetFont.

Interesting option.

I don't see it, how this is doable with TextSetFont? I'm running W10 scale layout set 100% and swill from .NET  side i get completely different results.

C# method:

[DllExport("MeasureTextDotNet", CallingConvention = CallingConvention.StdCall)]
public static bool MeasureTextDotNet([MarshalAs(UnmanagedType.LPWStr)] string text, 
                                    [MarshalAs(UnmanagedType.LPWStr)] string font,
                                    int size, 
                                    int fontStyleFlags, 
                                    ref int width, 
                                    ref int height)
{
    try
    {
        var point =  TextRenderer.MeasureText(text, new Font(font, size, (FontStyle)fontStyleFlags));
        width = point.Width;
        height = point.Height;
        return true;
    }
    catch (Exception ex)
    {
        return false;
    }
}

Mql script:

// System.Drawing.FontStyle
enum FontStyleFlags
{
  Regular = 0, 
  Bold = 1,  
  Italic = 2, 
  Underline = 4,
  Strikeout = 8
};

#import "TM.dll"
   bool MeasureTextDotNet(string text, string font, int size, FontStyleFlags flags, int &width, int &height);
#import

void OnStart()
  {
   string text = "test";
   string font  = "Arial";
   int size = 14;
        
   if(!TextSetFont(font, size, FW_REGULAR))
      Print("TextSetFont error="+(string)_LastError);
         
   uint w, h;
   if(!TextGetSize(text, w, h))
      Print("TextGetSize error="+(string)_LastError);
   Print("TextGetSize:       width=", w, " height=", h);      
     
   int wn, hn;    
   if(!MeasureTextDotNet(text, font, size, Regular, wn, hn))
      Print("MeasureTextDotNet error.");   
   Print("MeasureTextDotNet: width=", wn, " height=", hn);                  
   
   Print("Width ratio=", wn/(double)w, " height ratio=", hn/(double)h);
  }

Prints:

2018.03.01 06:32:13.188    FontSizeTest (GBPUSD,M15)    TextGetSize:       width=18 height=14
2018.03.01 06:32:13.289    FontSizeTest (GBPUSD,M15)    MeasureTextDotNet: width=41 height=22
2018.03.01 06:32:13.289    FontSizeTest (GBPUSD,M15)    Width ratio=2.277777777777778 height ratio=1.571428571428571

Old topic. You now have TerminalInfoInteger(TERMINAL_SCREEN_DPI)

But how does it help me to measure existing text size? Say, if i want to measure the [Symbol,period] description on the upper left corner of a chart?

Hello friends

I wrote an expert but the buttons and labels are not displayed well on other computers,

Can anyone help me with TerminalInfoInteger (TERMINAL_SCREEN_DPI) use ?

I read the document but I did not understand the meaning of button_width and base_width. Can anyone help?
