Detailed Description

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.

注:

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.

Styles

This class supports the following 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.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxSpinEvent& event)

Event macros for events emitted by this class:

• 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 received and then, if it wasn't vetoed, the SPIN event will be sent.

)

Default constructor.

wxSpinButton::wxSpinButton	(	wxWindow *	parent,
		wxWindowID	id = -1,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxSP_VERTICAL,
		const wxString &	name = "spinButton"
	)

Constructor, creating and showing a spin button.

Parameters:

parent	Parent window. Must not be NULL.
id	Window identifier. The value wxID_ANY indicates a default value.
pos	Window position. If wxDefaultPosition is specified then a default position is chosen.
size	Window size. If wxDefaultSize is specified then a default size is chosen.
style	Window style. See wxSpinButton class description.
name	Window name.
