53 @class wxSpinButton
54
55 A wxSpinButton has two small up and down (or left and right) arrow buttons.
56
57 It is often used next to a text control for increment and decrementing a value.
58 Portable programs should try to use wxSpinCtrl instead as wxSpinButton is not
59 implemented for all platforms but wxSpinCtrl is as it degenerates to a simple
60 wxTextCtrl on such platforms.
61
62 @note the range supported by this control (and wxSpinCtrl) depends on the
63 platform but is at least @c -0x8000 to @c 0x7fff. Under GTK and
64 Win32 with sufficiently new version of @c comctrl32.dll (at least 4.71
65 is required, 5.80 is recommended) the full 32 bit range is supported.
66
67 @beginStyleTable
68 @style{wxSP_HORIZONTAL}
69 Specifies a horizontal spin button (note that this style is not
70 supported in wxGTK).
71 @style{wxSP_VERTICAL}
72 Specifies a vertical spin button.
73 @style{wxSP_ARROW_KEYS}
74 The user can use arrow keys to change the value.
75 @style{wxSP_WRAP}
76 The value wraps at the minimum and maximum.
77 @endStyleTable
78
79 @beginEventEmissionTable{wxSpinEvent}
80 @event{EVT_SPIN(id, func)}
81 Generated whenever an arrow is pressed.
82 @event{EVT_SPIN_UP(id, func)}

84 @event{EVT_SPIN_DOWN(id, func)}
85 Generated when right/down arrow is pressed.
