I wite code by useing c++ .
When compile .err happen.
F01010.cxx(14) : error C2440: '=' : 'void (__thiscall F0101::*)(class
Fl_Widget *,void *)' から 'void (__cdecl *)(class Fl_Widget *,void *)' に変
換することはできません。(新しい動作 ; ヘルプを参照)
この変換が可能なコンテキストはありません。
-->
F01010.cxx(14) : error C2440: '=' :
Can not change 'void (__thiscall F0101::*)(class Fl_Widget *,void *)'
to 'void (__cdecl *)(class Fl_Widget *,void *)' .
Thank in advance.
