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.

Emitted either when the number of either axes or keys changes.

On X11 this will normally happen when the physical device routing events through the logical device changes (for example, user switches from the USB mouse to a tablet); in that case the logical device will change to reflect the axes and keys on the new physical device.

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
