From dcd95059bee58dce5e46a34f3d602b3e0f338b96 Mon Sep 17 00:00:00 2001 From: Darkvater Date: Sun, 3 Dec 2006 19:03:38 +0000 Subject: [PATCH] (svn r7337) -Feature: [win32] Add font selection by specifying a font-name, ala Fontconfig. Pretty messy if you ask me, but this is what you get when MS hides the font API in the deepest depths... thanks Rubidium for testing. --- fontcache.c | 235 +++++++++++++++++++++++++++++++++++++--------------- win32.h | 4 + 2 files changed, 174 insertions(+), 65 deletions(-) diff --git a/fontcache.c b/fontcache.c index 18d782acd1..4ad0e68aec 100644 --- a/fontcache.c +++ b/fontcache.c @@ -34,6 +34,170 @@ enum { SHADOW_COLOUR = 2, }; +#ifdef WIN32 +#include +#include +#include // SHGetFolderPath +#include "win32.h" + +#define FONT_DIR_NT "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Fonts" +#define FONT_DIR_9X "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Fonts" +static FT_Error GetFontByFaceName(const char *font_name, FT_Face *face) +{ + FT_Error err = FT_Err_Cannot_Open_Resource; + HKEY hKey; + LONG ret; + TCHAR vbuffer[MAX_PATH], dbuffer[256]; + char *font_path; + uint index; + + /* On windows NT (2000, NT3.5, XP, etc.) the fonts are stored in the + * "Windows NT" key, on Windows 9x in the Windows key.
