// Class : MouseAndKeyboard
|
|
// Description : Reads the mouse and/or keyboard data sent from a
|
|
// GraphicsWindow, and transmits it down the data graph.
|
|
//
|
|
// The mouse and keyboard devices are bundled together
|
|
// into one device here, because they interrelate so
|
|
// much. A mouse might be constrained by the holding
|
|
// down of the shift key, for instance, or the clicking
|
|
// of the mouse button might be handled in much the same
|
|
// way as a keyboard key.
|
|
//
|
|
// Mouse data is sent down the data graph as an x,y
|
|
// position as well as the set of buttons currently
|
|
// being held down; keyboard data is sent down as a set
|
|
// of keypress events in an EventDataTransition. To
|
|
// throw these events to the system, you must attach an
|
|
// EventThrower to the MouseAndKeyboard object;
|
|
// otherwise, the events will be discarded.
