FOX-TOOLKIT的網站及簡介：
www.fox-toolkit.org
FOX is a C++ based Toolkit for developing Graphical User Interfaces easily and
effectively. It offers a wide, and growing, collection of Controls, and provides
state of the art facilities such as drag and drop, selection, as well as OpenGL
widgets for 3D graphical manipulation. FOX also implements icons, images, and
user-convenience features such as status line help, and tooltips.
Tooltips may even be used for 3D objects!
剛開始學習FOX TOOLKIT，做了一個簡單的文本顯示例子，在Windows平臺上我使用了MultiByteToWideChar來實現代碼頁轉換，如果誰能有基于FOX的解決方案，歡迎進行指點和幫助。
對比WTL，FOX在界面設計和消息傳遞上要更加簡潔和靈活，缺點是不支持本地UI。在本程序中FXText控件的執行效率較低，可以考慮使用fxscintilla來代替。
