Device.connectChanged

gulong connectChanged(T)(T callback,  Flag!"After" after =  No.After) if (isCallable!T
    &&  is(ReturnType!T ==  void)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0] :  gdk.device.Device)))
   &&  Parameters!T.length <  2)

Connect to Changed signal.

The ::changed signal is emitted either when the #GdkDevice has changed the number of either axes or keys. For example In X this will normally happen when the slave device routing events through the master device changes (for example, user switches from the USB mouse to a tablet), in that case the master device will change to reflect the new slave device axes and keys.

Parameters

`callback`	signal callback delegate or function to connect `void callback(gdk.device.Device device)` `device` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
