fltk.core.shim

FLTK C Shim Bindings

This module provides D bindings to the FLTK C shim library, which wraps the FLTK C++ toolkit with a stable C ABI. All FLTK objects are represented as opaque handles.

Memory Management:

  • Objects created with *_new() functions must be destroyed with *_delete()
  • The shim owns the underlying C++ objects
  • Handles become invalid after deletion

Thread Safety:

  • FLTK is not thread-safe; all GUI operations must occur on the main thread
  • Callbacks may be invoked from the main thread during event processing

Example: 

import fltk.core.shim;

void main() {
   auto window = fltk_window_new(300, 200, "Hello");
   if (window) {
      fltk_window_show(window);
      fltk_run();
      fltk_window_delete(window);
   }
}
