<description><p>A <seeerl marker="wxSpinButton"><c>wxSpinButton</c></seeerl> has two small up and down (or left and right) arrow buttons.
      </p><p>It is often used next to a text control for increment and decrementing a value. Portable programs should try to use <seeerl marker="wxSpinCtrl"><c>wxSpinCtrl</c></seeerl> instead as <seeerl marker="wxSpinButton"><c>wxSpinButton</c></seeerl> is not implemented for all platforms but <seeerl marker="wxSpinCtrl"><c>wxSpinCtrl</c></seeerl> is as it degenerates to a simple <seeerl marker="wxTextCtrl"><c>wxTextCtrl</c></seeerl> on such platforms.
      </p><p>Note: the range supported by this control (and <seeerl marker="wxSpinCtrl"><c>wxSpinCtrl</c></seeerl>) depends on the platform but is at least <c>-0x8000</c> to <c>0x7fff</c>. Under GTK and Win32 with sufficiently new version of <c>comctrl32.dll</c> (at least 4.71 is required, 5.80 is recommended) the full 32 bit range is supported.
