public interface MouseEvent
The MouseEvent
interface provides specific contextual
information associated with Mouse events.
The detail
attribute inherited from UIEvent
indicates the number of times a mouse button has been pressed and
released over the same screen location during a user action. The
attribute value is 1 when the user begins this action and increments by 1
for each full sequence of pressing and releasing. If the user moves the
mouse between the mousedown and mouseup the value will be set to 0,
indicating that no click is occurring.
In the case of nested elements mouse events are always targeted at the most deeply nested element. Ancestors of the targeted element may use bubbling to obtain notification of mouse events which occur within its descendent elements.
See also the Document Object Model (DOM) Level 2 Events Specification.

boolean |
getAltKey()
Used to indicate whether the 'alt' key was depressed during the firing of the event. |

getButton()
During mouse events caused by the depression or release of a mouse button, button is used to indicate which mouse button
changed state. |

getClientX()
The horizontal coordinate at which the event occurred relative to the DOM implementation's client area. |
int |
getClientY()
The vertical coordinate at which the event occurred relative to the DOM implementation's client area. |
boolean |
getCtrlKey()
Used to indicate whether the 'ctrl' key was depressed during the firing of the event. |
boolean |
getMetaKey()
Used to indicate whether the 'meta' key was depressed during the firing of the event. |

getRelatedTarget()
Used to identify a secondary EventTarget related to a UI
event. |
int |
getScreenX()
The horizontal coordinate at which the event occurred relative to the origin of the screen coordinate system. |
int |
getScreenY()
The vertical coordinate at which the event occurred relative to the origin of the screen coordinate system. |

Used to indicate whether the 'shift' key was depressed during the firing of the event. |

short getButton()
button
is used to indicate which mouse button
changed state. The values for button
range from zero to
indicate the left button of the mouse, one to indicate the middle
button if present, and two to indicate the right button. For mice
configured for left handed use in which the button actions are
reversed the values are instead read from right to left.
EventTarget getRelatedTarget()
EventTarget
related to a UI
event. Currently this attribute is used with the mouseover event to
indicate the EventTarget
which the pointing device
exited and with the mouseout event to indicate the
EventTarget
which the pointing device entered.

initMouseEvent
method is used to initialize the value
of a MouseEvent
created through the
DocumentEvent
interface. This method may only be called
before the MouseEvent
has been dispatched via the
dispatchEvent
method, though it may be called multiple
times during that phase if necessary. If called multiple times, the
final invocation takes precedence.
