wxWidgets uses bit vectors to configure windows on creation, the so-called styles. wx.NET used to provide such style flags as integer constants. These constants had the same name as their counterparts in C++.
wx.NET now makes a move to exploit the opportunities of the .NET framework. Styles for windows and sizers are now enumerations with attribute [Flags]. This eases use of wx.NET for those developers working with Visual Studio's IntelliSence and for those that do not use the C++ original of wxWidgets. Unfortunately, existing code for wx.NET needs to be ported.
