nim-fww

Nim bindings of various Win32 APIs for native Windows GUI application development (e.g. Direct2D, DirectWrite, WIC…​).

Supports Nim v1.6.x, v2.0.x, v2.2.x.

Available APIs

• Direct2D:

  • Direct2D API bindings (fww/d2d1)

  • Pure Nim Math library (fww/d2d1_maths)

  • Typed API for Built-in Effects (fww/d2d1_effects)

• DirectWrite (fww/dwrite)

• Windows Imaging Component (WIC) (fww/wic)

• Clipboard (fww/win32clipboard)

• The COM Library (fww/win32com)

• Smart pointers for COM objects (fww/comrefs)

• Windowing and Messaging:

  • Bindings for the Win32 Windows and Messaging API (fww/win32wm)

  • WM_* constants (fww/win32wmconsts)

  • (Extension) A high-level windowing framework (fww/wmworks)

• QueryPerformanceCounter (QPC) (fww/win32qpc)

• Threading and thread synchronization (fww/win32threads)

• The Windows Shell:

  • Shell Filesystem operations (fww/win32shellfs)

  • Drag-and-drop (fww/win32dropfiles)

(…​ more to come as needed)

Demos

See the demos/ directory for various demos.

SimpleDirect2DApplication

A port of Microsoft’s Simple Direct2D Application code example to nim-fww.

This demo demonstrates the use of:

• Direct2D (fww/d2d1) for rendering.

• DirectWrite (fww/dwrite) for text layout.

• WIC (fww/wic) for image loading, resizing and pixel format conversion.

• fww/win32wm and fww/wmworks for creating windows and responding to events.

• fww/winres for compile-time generation of the resource object file with the application manifest and embedded data.

Design notes

This project only focuses on native Win32 GUI development. It does not aim for full API coverage (especially if the API is obsolete). winim can be used (in conjunction with nim-fww) if full Win32 API coverage is needed.
