wxWidgets defines a special identifier value wxID_ANY which is used in the following two situations:
Another standard special identifier value is wxID_NONE: this is a value which is not matched by any other id.
wxWidgets also defines a few standard command identifiers which may be used by the user code and also are sometimes used by wxWidgets itself. These reserved identifiers are all in the range between wxID_LOWEST and wxID_HIGHEST and, accordingly, the user code should avoid defining its own constants in this range.
