The main include file is "wx/wx.h"; this includes the most commonly used modules of wxWidgets.
To save on compilation time, include only those header files relevant to the source file. If you are using precompiled headers, you should include the following section before any other includes:
// For compilers that support precompilation, includes "wx.h". #include <wx/wxprec.h> #ifdef __BORLANDC__ #pragma hdrstop #endif #ifndef WX_PRECOMP // Include your minimal set of headers here, or wx.h #include <wx/wx.h> #endif ... now your other include files ...
The file "wx/wxprec.h" includes "wx/wx.h". Although this incantation may seem quirky, it is in fact the end result of a lot of experimentation, and several Windows compilers to use precompilation which is largely automatic for compilers with necessary support. Currently it is used for Visual C++ (including embedded Visual C++), Borland C++, Open Watcom C++ and newer versions of GCC.
