Standard event identifiers

wxPython defines a special identifier value ID_ANY (-1) which is used in the following two situations:

• When creating a new window you may specify ID_ANY to let wxPython assign an unused identifier to it automatically
• When installing an event handler using EvtHandler.Bind, you may use it to indicate that you want to handle the events coming from any control, regardless of its identifier

Another standard special identifier value is ID_NONE: this is a value which is not matched by any other id.

wxPython also defines a few standard command identifiers which may be used by the user code and also are sometimes used by wxPython itself. These reserved identifiers are all in the range between ID_LOWEST and ID_HIGHEST and, accordingly, the user code should avoid defining its own constants in this range (e.g. by using NewId ()).

Refer to the list of stock items for the subset of standard IDs which are stock IDs as well.
