# ============================================================
# fltk — Viper 的 FLTK GUI 绑定包（对接 cfltk C API）
#
# 用户用法:
#   import fltk
#   win = fltk.Fl_Window(400, 300, "Hello")
#   box = fltk.Fl_Box(10, 10, 380, 40, "Hello, World!")
#   btn = fltk.Fl_Button(150, 100, 100, 30, "Click")
#   win.end()
#   win.show()
#   fltk.Fl.run()
#
# 说明:
#   * 本包只做 extern FFI（fltk._cfl* 模块）+ 少量 Pythonic 包装类；
#     所有 FLTK 对象都是不透明指针，方法即 cfltk 的 Fl_<类>_<动作>。
#   * 完整 C API 通过 `from fltk._cfl import *` 等直接可用。
#   * 回调（Fl_Callback 等）在 FFI 中按 bytes 不透明处理：Viper 端
#     暂无法传函数指针，事件驱动请用 Fl.check()/Fl.event*() 轮询。
