# wxSpinCtrl (wx v2.4.3)

View Source

`wxSpinCtrl` combines `wxTextCtrl` and `wxSpinButton` in one control.

## Styles

This class supports the following styles:

- wxSP_ARROW_KEYS: The user can use arrow keys to change the value.

- wxSP_WRAP: The value wraps at the minimum and maximum.

- wxTE_PROCESS_ENTER: Indicates that the control should generate `wxEVT_TEXT_ENTER` events. Using this style will prevent the user from using the Enter key for dialog navigation (e.g. activating the default button in the dialog) under MSW.

- wxALIGN_LEFT: Same as wxTE_LEFT for `wxTextCtrl`: the text is left aligned (this is the default).

- wxALIGN_CENTRE_HORIZONTAL: Same as wxTE_CENTRE for `wxTextCtrl`: the text is centered.

- wxALIGN_RIGHT: Same as wxTE_RIGHT for `wxTextCtrl`: the text is right aligned.

See:

- `wxSpinButton`

- `wxControl`

This class is derived, and can use functions, from:

- `wxControl`

- `wxWindow`

- `wxEvtHandler`

                         {initial, integer()}.

Constructor, creating and showing a spin control.

If `value` is non-empty, it will be shown in the text entry part of the control and if it has numeric value, the initial numeric value of the control, as returned by `getValue/1` will also be determined by it instead of by `initial`. Hence, it only makes sense to specify `initial` if `value` is an empty string or is not convertible to a number, otherwise `initial` is simply ignored and the number specified by `value` is used.

See: `create/3`

# setRange(This, MinVal, MaxVal)

    -spec setRange(This, MinVal, MaxVal) -> ok
                      when This :: wxSpinCtrl(), MinVal :: integer(), MaxVal :: integer().

Sets range of allowable values.

Notice that calling this method may change the value of the control if it's not inside the new valid range, e.g. it will become `minVal` if it is less than it now. However no `wxEVT_SPINCTRL` event is generated, even if it the value does change.

Note: Setting a range including negative values is silently ignored if current base is set to 16.

# setSelection(This, From, To)

    -spec setSelection(This, From, To) -> ok when This :: wxSpinCtrl(), From :: integer(), To :: integer().

Select the text in the text part of the control between positions `from` (inclusive) and `to` (exclusive).

This is similar to `wxTextCtrl:setSelection/3`.

Note: this is currently only implemented for Windows and generic versions of the control.

# setValue/2

    -spec setValue(This, Value) -> ok when This :: wxSpinCtrl(), Value :: integer();
                  (This, Text) -> ok when This :: wxSpinCtrl(), Text :: unicode:chardata().

Sets the value of the spin control.

It is recommended to use the overload taking an integer value instead.

Notice that, unlike `wxTextCtrl:setValue/2`, but like most of the other setter methods in wxWidgets, calling this method does not generate any events as events are only generated for the user actions.
