How to set bold label with ObjectSetText in MQL

Question

Is there a way to set bold text using ObjectSetText() function in MQL4.

Should a font name be for example "Arial Bold" or can I set a path to the font .ttf-file?

If a path option is possible, is that path relative or absolute?

Answer 1

ObjectSetText() uses O/S-registered fonts & only limited controls

as one may test on GUI panels, MQL4 operations do not have full type-setting font-manipulation controls available via code

_{( this is all about trading, isn't it? )}

Check what fonts are available from your O/S:

_{( or from used Docker/WINE thin-wrapper container )}

So in MQL4 code there will thus simply be a string-typed or #define-ed literal specification of the font name and one may additionally set aFontSIZE + aFontCOLOUR attribute(s)

#define           clrSignalLABEL       clrAqua                  // LITERAL-way
#define           iLabelFontSIZE       24

string            signalTextFONT       'Times New Roman';       // STRING-way
