Field Detail

modifierKeys

protected HashSet modifierKeys

The modifier keys in effect at the time of the event.

Constructor Detail

DOMMouseEvent

public DOMMouseEvent()

Method Detail

getScreenX

public int getScreenX()

DOM: screenX indicates the horizontal coordinate at which the event occurred relative to the origin of the screen coordinate system.

Specified by:: getScreenX in interface MouseEvent

getScreenY

public int getScreenY()

DOM: screenY indicates the vertical coordinate at which the event occurred relative to the origin of the screen coordinate system.

Specified by:: getScreenY in interface MouseEvent

getClientX

public int getClientX()

DOM: clientX indicates the horizontal coordinate at which the event occurred relative to the DOM implementation's client area.

Specified by:: getClientX in interface MouseEvent

getClientY

public int getClientY()

DOM: clientY indicates the vertical coordinate at which the event occurred relative to the DOM implementation's client area.

Specified by:: getClientY in interface MouseEvent

getCtrlKey

public boolean getCtrlKey()

DOM: ctrlKey indicates whether the 'ctrl' key was depressed during the firing of the event.

Specified by:: getCtrlKey in interface MouseEvent

getShiftKey

public boolean getShiftKey()

DOM: shiftKey indicates whether the 'shift' key was depressed during the firing of the event.

Specified by:: getShiftKey in interface MouseEvent

getAltKey

public boolean getAltKey()

DOM: altKey indicates whether the 'alt' key was depressed during the firing of the event. On some platforms this key may map to an alternative key name.

Specified by:: getAltKey in interface MouseEvent

getMetaKey

public boolean getMetaKey()

DOM: metaKey indicates whether the 'meta' key was depressed during the firing of the event. On some platforms this key may map to an alternative key name.

Specified by:: getMetaKey in interface MouseEvent

getButton

public short getButton()

DOM: During mouse events caused by the depression or release of a mouse button, 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.

Specified by:: getButton in interface MouseEvent

getRelatedTarget

public EventTarget getRelatedTarget()

DOM: Used to identify a secondary 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.

Specified by:: getRelatedTarget in interface MouseEvent

getModifierState

public boolean getModifierState(String keyIdentifierArg)

DOM: Returns whether the given modifier key was pressed at the time of the event.

Specified by:: getModifierState in interface MouseEvent

Parameters:: keyIdentifierArg - A modifier key identifier, as defined by the KeyboardEvent.keyIdentifier attribute. Common modifier keys are "Alt", "AltGraph", "CapsLock", "Control", "Meta" , "NumLock", "Scroll", or "Shift".
Note: If an application wishes to distinguish between right and left modifiers, this information could be deduced using keyboard events and KeyboardEvent.keyLocation.
Returns:: true if it is modifier key and the modifier is activated, false otherwise.

getModifiersString

public String getModifiersString()

Returns the modifiers string for this event.

initMouseEvent

public void initMouseEvent(String typeArg,
                           boolean canBubbleArg,

DOM: The 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.
