### Signal

# Gtk SpinButton::input

since: 4.0

#### Declaration

    gint
    input (
      GtkSpinButton* self,
      gdouble* new_value,
      gpointer user_data
    )

#### Description [src]

Emitted to convert the users input into a double value.

The signal handler is expected to use `gtk_editable_get_text()` to retrieve the text of the spinbutton and set `new_value` to the new value.

The default conversion uses g_strtod().

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.
Available since: 4.0

#### Parameters

`new_value`

  Type: `gdouble*`

  Return location for the new value.

  The argument will be set by the function.

#### Return value

Type: `gint`

`TRUE` for a successful conversion, `FALSE` if the input was not handled, and `GTK_INPUT_ERROR` if the conversion failed.
