|
|
// CLASS DESCRIPTION (MEvent)
|
|
//
|
|
// The MEvent class is used for querying system events such as mouse presses.
|
|
//
|
|
// Events are handled by an MPxContext derived class in which MEvents are passed
|
|
// and can be accessed.
|
|
//
|
|
// Since Maya has default actions for several events, only a subset are
|
|
// available through the API.
|
|
// The events that can be accessed are:
|
|
// buttonPress - mouse button press event (left & middle only)
|
|
// buttonRelease - mouse buttons release event (left & middle only)
|
|
// mouseDrag - mouse button drag event (left & middle only)
|
|
// hold - mouse button hold event (left & middle only)
|
|
// deleteEvent - delete/backspace key event
|
|
// commandCompletion - complete key event
|
|
//
|
|
// Several modifiers for events are also accessible through the API. Modifiers
|
|
// are actions that occur during an event. For example, holding down the shift
|
|
// key while pressing a mouse button causes a button press event to occur with
|
|
// a shift modifier.
|
|
//
|
|
// A modifier can be used to determine if two mouse events occur simulaneously.
|
|
// The second mouse event is registered as a modifier in the hold event of the
|
|
// first mouse button. So if you wanted to determine if both the left and
|
|
// middle buttons are pressed then you would query the modifier in the hold
|
|
// event of the first mouse button using the isModifierMiddleMouseButton() and
|
|
// isModifierLeftMouseButton() methods.
|
|
