Enumerates all the fonts, with all available styles, installed in the system.
This resembles the standard Windows GDI ChooseFont dialog, but works with the DirectWrite subsystem. All sample fonts rendering is done with the Direct2D.
The dialog can easily be added into any C++ project as C++20 modules. Written in pure Win32 API, no any other dependencies.

On dialog exit a std::optional<DWFONTINFO> is returned. The DWFONTINFO struct possesses all the choosen font's information, similar to LOGFONT. This information can then be used to create text format object with the IDWriteFactory::CreateTextFormat Direct2D method call.

Usage

1. Add all files from the DWFontChoose subdirectory into your project
2. import DWFontChoose;
3. Call the DWFontChoose(); global method

import DWFontChoose;

int WinMain() {
    const auto optFontInfo = DWFontChoose();
    ...
    return 0;
}

DWFONTINFO

struct DWFONTINFO {
    std::wstring        wstrFamilyName;
    std::wstring        wstrLocale;
    DWRITE_FONT_WEIGHT  eWeight { };
    DWRITE_FONT_STRETCH eStretch { };
    DWRITE_FONT_STYLE   eStyle { };
    float               flSizeDIP { }; //Font size in Device Independent Pixels (not points).
};
