  12     This event class is used for the events generated by wxSpinButton and wxSpinCtrl.
  13
  14     @beginEventTable{wxSpinEvent}
  15     @event{EVT_SPIN(id, func)}
  16         Generated whenever an arrow is pressed.
  17     @event{EVT_SPIN_UP(id, func)}
  18         Generated when left/up arrow is pressed.
  19     @event{EVT_SPIN_DOWN(id, func)}
  20         Generated when right/down arrow is pressed.
  21     @endEventTable

  23     Note that if you handle both SPIN and UP or DOWN events, you will be notified
  24     about each of them twice: first the UP/DOWN event will be received and then,
  25     if it wasn't vetoed, the SPIN event will be sent.

  54     @class wxSpinButton
  55
  56     A wxSpinButton has two small up and down (or left and right) arrow buttons.
  57
  58     It is often used next to a text control for increment and decrementing a value.
  59     Portable programs should try to use wxSpinCtrl instead as wxSpinButton is not
  60     implemented for all platforms but wxSpinCtrl is as it degenerates to a simple
  61     wxTextCtrl on such platforms.
  62
  63     @note the range supported by this control (and wxSpinCtrl) depends on the
  64           platform but is at least @c -0x8000 to @c 0x7fff. Under GTK and
  65           Win32 with sufficiently new version of @c comctrl32.dll (at least 4.71
  66           is required, 5.80 is recommended) the full 32 bit range is supported.
  67
  68     @beginStyleTable
  69     @style{wxSP_HORIZONTAL}
  70            Specifies a horizontal spin button (note that this style is not
  71            supported in wxGTK).
  72     @style{wxSP_VERTICAL}
  73            Specifies a vertical spin button.
  74     @style{wxSP_ARROW_KEYS}
  75            The user can use arrow keys to change the value.
  76     @style{wxSP_WRAP}
  77            The value wraps at the minimum and maximum.
  78     @endStyleTable
  79
  80     @beginEventEmissionTable{wxSpinEvent}
  81     @event{EVT_SPIN(id, func)}
  82         Generated whenever an arrow is pressed.
  83     @event{EVT_SPIN_UP(id, func)}
  84         Generated when left/up arrow is pressed.
  85     @event{EVT_SPIN_DOWN(id, func)}
  86         Generated when right/down arrow is pressed.
  87     @endEventTable
  88
  89     Note that if you handle both SPIN and UP or DOWN events, you will be notified
  90     about each of them twice: first the UP/DOWN event will be received and then,
  91     if it wasn't vetoed, the SPIN event will be sent.
