// Class : VrpnButton
|
|
// Description : This is the actual interface to a particular VRPN
|
|
// button device, and all of its numbered buttons. A
|
|
// pointer to this object is stored in the VrpnClient
|
|
// class for each differently-named VRPN button device
|
|
// we connect to.
|
|
//
|
|
// The VRPN callbacks go here, which in turn get
|
|
// vectored out to any VrpnButtonDevice objects that
|
|
// register with this. When the last VrpnButtonDevice
|
|
// object unregisters, the VrpnButton will be deleted
|
|
// by the VrpnClient.
|
|
//
|
|
// This class does not need to be exported from the DLL.
