|

| 48 | * This event is generated for a mouse event. There are three main categories
|
|---|
| 49 | * of mouse events: Regular events include pressing, releasing, and clicking
|
|---|
| 50 | * buttons, as well as moving over the boundary of the unobscured portion of
|
|---|
| 51 | * a component. Motion events include movement and dragging. Wheel events are
|
|---|
| 52 | * covered separately by the subclass MouseWheelEvent.
|
|---|
| 53 | *
|
|---|
| 54 | * <p>A mouse event is tied to the unobstructed visible component that the
|
|---|
| 55 | * mouse cursor was over at the time of the action. The button that was
|
|---|
| 56 | * most recently pressed is the only one that shows up in
|
|---|
| 57 | * <code>getModifiers</code>, and is returned by <code>getButton</code>,
|
|---|
| 58 | * while all buttons that are down show up in <code>getModifiersEx</code>.
|
|---|
| 59 | *
|
|---|
| 60 | * <p>Drag events may be cut short if native drag-and-drop operations steal
|
|---|
| 61 | * the event. Likewise, if a mouse drag exceeds the bounds of a window or
|
|---|
| 62 | * virtual device, some platforms may clip the path to fit in the bounds of
|
|---|
| 63 | * the component.
