macOS Determine particular symbol width in TextField

[i.yalovecky]

How i can do it? User can change Fontsize and font family in NSTextField, and i need to get width for specified symbol. Thanks.

Probably something like

bool CGFontGetGlyphBBoxes (
CGFontRef font,
const CGGlyph glyphs[],
size_t count,
CGRect bboxes[]
);

Pass it your font, your symbol (glyph), 1, and a CGRect and if the function returns true then CGRect.width should contain the appropriate width you are looking for.

How i can convert unichar or NSString* to glyphs?

Have you considered putting the character into a NSString and using
sizeWithAttributes: (passing an appropriate dictionary of attributes)?
