FensterB

Fenster with some bloated code

License

Code is distributed under MIT license, feel free to use it in your proprietary projects as well.

Main changes

  • Source split by system
  • Platform-agnostic structure for audio
  • Mouse: Left, Right, Middle, Scrollup/down
  • Full Screen mode (fenster_fullscreen = 0 to windowed, 1 to fullscreen)
  • Buf size is handled internally
  • Basic 2d shapes
  • Window resize (fenster_resize)
  • Cursor pointer (fenster_cursor = 0 hidden, 1 normal, 2 pointer, 3 progress, 4 crosshair, 5 text)
  • Sync command
  • Fast fill (memset for 0, avx2 (windows, linux) or neon (mac, arm, etc) for non-zero)
  • TTF text drawing with basic formatting syntax (\\c(color) \\b(ackground color (defaults to magic number 0xFFFFFFFF for transparency) \\s(font size) \\n(newline) \\p(spacing) \\h(line spacing))
  • Changed: array on modkeys, mouse pos
struct fenster {
  const char *title;
  int width;
  int height;
  int keys[256];      // keys are mostly ASCII, but arrows are 17..20
  int keysp[256];     // similar to mclick but for keys. Unexpected behavior. On Linux it always returns 1 if held for more than 1~2 seconds.
  int modkeys[4];     // ctrl, shift, alt, meta
  int mpos[2];        // mouse x, y
  int mclick[5];      // left, right, middle, scroll up, scroll down (refreshed after loop)
  int mhold[3];       // left, right, middle (persistent until button release)
  int64_t lastsync;   // last sync time
  int resized;
};
