petzold-pw5e-zig's Introduction

petzold-pw5e-zig

Zig transliteration of Charles Petzold's excellent book Programming Windows 5th Edition ISBN-10 157231995X

Not much content yet. The Zig (beta) release is at 0.10.0 at the time of writing.

The code works with Zig 0.9.1 - it requires tweaking to work with 0.10.0 and that won't happen until after zigwin32 has been updated to work with Zig 0.10.0

Notes

This project uses zigwin32 to eliminate importing the Windows header files directly. (Which is good as @cImport() has issues parsing the complexities of said Windows header files.)
Unlike C/C++ there is no WIN32_LEAN_AND_MEAN to reduce the #include C header file burden. Zig is quick enough.
marlersoft/zigwin32gen#9 causes occasional memory align panics with CreateWindowExW and other functions. To fix align(1) needs to be added to the offending parameter in the zigwin32 declarations.
- CreateWindowExW(), CreateWindowExA() - 2nd (lpClassName) parameter
- LoadImageW(), LoadImageA() - 2nd (name) parameter
TextOutW(), TextOutA() the lpString parameter does not need to be zero terminated.
IDC_ARROW is present in zigwin32, but IDC_WAIT and others have been skipped. Probably to avoid the align(1) issues.
LoadIcon & LoadCursor functions have been superseded by the LoadImage function.
GetWindowLongPtr/GetWindowLongPtr functions are correctly mapped to GetWindowLong/SetWindowLong for 32 bit systems. No need to panic.
There is no replacement for the CreateWindow macro in WinUser.h that maps to CreateWindowEx
missing StringCchCopy and its ilk from strsafe.h
