wxSpinButton

Задать вопрос на форуме...

A wxSpinButton has two small up and down (or left and right) arrow buttons. It is often used next to a text control for increment and decrementing a value. Portable programs should try to use wxSpinCtrl instead as wxSpinButton is not implemented for all platforms but wxSpinCtrl is as it degenerates to a simple wxTextCtrl on such platforms.

NB: the range supported by this control (and wxSpinCtrl) depends on the platform but is at least -0x8000 to 0x7fff. Under GTK and Win32 with sufficiently new version of comctrl32.dll (at least 4.71 is required, 5.80 is recommended) the full 32 bit range is supported.

Window styles

wxSP_HORIZONTAL	Specifies a horizontal spin button (note that this style is not supported in wxGTK).
wxSP_VERTICAL	Specifies a vertical spin button.
wxSP_ARROW_KEYS	The user can use arrow keys to change the value.
wxSP_WRAP	The value wraps at the minimum and maximum.

See also window styles overview.

Event handling

To process input from a spin button, use one of these event handler macros to direct input to member functions that take a wxSpinEvent argument:

EVT_SPIN(id, func)	Generated whenever an arrow is pressed.
EVT_SPIN_UP(id, func)	Generated when left/up arrow is pressed.
EVT_SPIN_DOWN(id, func)	Generated when right/down arrow is pressed.

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