  10     @class wxSpinCtrl
  11
  12     wxSpinCtrl combines wxTextCtrl and wxSpinButton in one control.
  13
  14     @beginStyleTable
  15     @style{wxSP_ARROW_KEYS}
  16         The user can use arrow keys to change the value.
  17     @style{wxSP_WRAP}
  18         The value wraps at the minimum and maximum.
  19     @style{wxTE_PROCESS_ENTER}
  20         Indicates that the control should generate @c wxEVT_COMMAND_TEXT_ENTER
  21         events. Using this style will prevent the user from using the Enter key
  22         for dialog navigation (e.g. activating the default button in the
  23         dialog) under MSW.
  24     @style{wxALIGN_LEFT}
  25         Same as wxTE_LEFT for wxTextCtrl: the text is left aligned.
  26     @style{wxALIGN_CENTRE_HORIZONTAL}
  27         Same as wxTE_CENTRE for wxTextCtrl: the text is centered.
  28     @style{wxALIGN_RIGHT}
  29         Same as wxTE_RIGHT for wxTextCtrl: the text is right aligned (this is
  30         the default).
  31     @endStyleTable
  32
  33
  34     @beginEventEmissionTable{wxSpinEvent}
  35     @event{EVT_SPINCTRL(id, func)}
  36         Process a wxEVT_COMMAND_SPINCTRL_UPDATED event, which is generated
  37         whenever the numeric value of the spin control is updated.
  38     @endEventTable
  39
  40     You may also use the wxSpinButton event macros, however the corresponding events
  41     will not be generated under all platforms. Finally, if the user modifies the
  42     text in the edit part of the spin control directly, the EVT_TEXT is generated,
  43     like for the wxTextCtrl. When the use enters text into the text area, the text
  44     is not validated until the control loses focus (e.g. by using the TAB key).
  45     The value is then adjusted to the range and a wxSpinEvent sent then if the value
  46     is different from the last value sent.

  67         the control, as returned by GetValue() will also be determined by it
  68         instead of by @a initial. Hence, it only makes sense to specify @a
  69         initial if @a value is an empty string or is not convertible to a
