    &&  is(ReturnType!T ==  int)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.out_ &&  is(Parameters!T[0]  ==  double)))

Connect to Input signal.

Emitted to convert the user's input into a double value.

The signal handler is expected to use [gtk.editable.Editable.getText] to retrieve the text of the spinbutton and set new_value to the new value.

The default conversion uses funcGLib.strtod.

See [gtk.spin_button.SpinButton.input].

Parameters

`callback`	signal callback delegate or function to connect `int callback(out double newValue, adw.spin_row.SpinRow spinRow)` `newValue` return location for the new value (optional) `spinRow` the instance the signal is connected to (optional) `Returns` `TRUE` for a successful conversion, `FALSE` if the input was not handled, and [gtk.types.INPUT_ERROR] if the conversion failed.
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)
