(This function is part of SDL_ttf, a separate library from SDL.)

TTF_FontIsFixedWidth

Query whether a font is fixed-width.

Header File

Defined in <SDL3_ttf/SDL_ttf.h>

Syntax

bool TTF_FontIsFixedWidth(const TTF_Font *font);

Function Parameters

const TTF_Font *

font

the font to query.

Return Value

(bool) Returns true if the font is fixed-width, false otherwise.

Remarks

A "fixed-width" font means all glyphs are the same width across; a lowercase 'i' will be the same size across as a capital 'W', for example. This is common for terminals and text editors, and other apps that treat text as a grid. Most other things (WYSIWYG word processors, web pages, etc) are more likely to not be fixed-width in most cases.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL_ttf 3.0.0.
