// NOTES
//
// * Examples of custom property classes are in sampleprops.cpp.
//
// * Additional ones can be found below.
//
// * Currently there is no example of a custom property editor. However,
//   SpinCtrl editor sample is well-commented. It can be found in
//   src/propgrid/advprops.cpp.
//
// * To find code that populates the grid with properties, search for
//   string "::Populate".
//
// * To find code that handles property grid changes, search for string
//   "::OnPropertyGridChange".
//

// For compilers that support precompilation, includes "wx/wx.h".
