libui bindings for Euphoria

Status

  • Wrapper code is complete; new features will be added as they arrive in libui.
  • Testing is incomplete. More examples are welcome.

This wrapper should be stable but keep in mind that libui is still in alpha status.

Notes

Wrapper Style

A keen observer might notice the seemingly unorthodox C wrapper code used in ui.e. What I've done here, is use a map to provide string lookups for function names instead of using constants. This is an experiment in providing a cleaner C library wrapper. The calls to define_c_func/proc look a lot more like attributes used in C# or VB.NET. I have not compared this method to using constants, so I'm not sure if or by how much this might be slower.

Original Code

constant _uiNewWindow = define_c_func( libui, "uiNewWindow", {C_POINTER,C_INT,C_INT,C_INT}, C_POINTER )
public function uiNewWindow( sequence title, atom width, atom height, atom hasMenubar )
    return c_func( _uiNewWindow, {allocate_string(title,1),width,height,hasMenubar} )
end function

Wrapper Code

define_c_func( libui, "uiNewWindow", {C_POINTER,C_INT,C_INT,C_INT}, C_POINTER )
public function uiNewWindow( sequence title, atom width, atom height, atom hasMenubar )
    return c_func( "uiNewWindow", {allocate_string(title,1),width,height,hasMenubar} )
end function
