fix from Francesco for the latest version of wxPresets

[wxWidgets.git] / include / wx / os2 / mdi.h

/////////////////////////////////////////////////////////////////////////////
// Name:        mdi.h
// Purpose:     MDI (Multiple Document Interface) classes.
//              This doesn't have to be implemented just like Windows,
//              it could be a tabbed design as in wxGTK.
