Inheritance diagram for DOM::MouseEvent:

DOM::UIEvent DOM::Event List of all members.

Detailed Description

Introduced in DOM Level 2.

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.

bool MouseEvent::altKey (  )  const

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

On some platforms this key may map to an alternative key name.

Definition at line 427 of file dom2_events.cpp.

unsigned short MouseEvent::button (  )  const

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.

Definition at line 443 of file dom2_events.cpp.

long MouseEvent::clientX (  )  const

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

Definition at line 395 of file dom2_events.cpp.

long MouseEvent::clientY (  )  const

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

Definition at line 403 of file dom2_events.cpp.

bool MouseEvent::ctrlKey (  )  const

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

Definition at line 411 of file dom2_events.cpp.

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. Parameters

Parameters:
typeArg Specifies the event type.
canBubbleArg Specifies whether or not the event can bubble.
cancelableArg Specifies whether or not the event's default action can be prevented.
viewArg Specifies the Event's AbstractView.
detailArg Specifies the Event's mouse click count.
screenXArg Specifies the Event's screen x coordinate
screenYArg Specifies the Event's screen y coordinate
clientXArg Specifies the Event's client x coordinate
clientYArg Specifies the Event's client y coordinate
ctrlKeyArg Specifies whether or not control key was depressed during the Event.
altKeyArg Specifies whether or not alt key was depressed during the Event.
shiftKeyArg Specifies whether or not shift key was depressed during the Event.
metaKeyArg Specifies whether or not meta key was depressed during the Event.
buttonArg Specifies the Event's mouse button.
relatedTargetArg Specifies the Event's related EventTarget.

bool MouseEvent::metaKey (  )  const

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

On some platforms this key may map to an alternative key name.

Definition at line 435 of file dom2_events.cpp.

Node MouseEvent::relatedTarget (  )  const

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.

Definition at line 451 of file dom2_events.cpp.

long MouseEvent::screenX (  )  const

The horizontal coordinate at which the event occurred relative to the origin of the screen coordinate system.

Definition at line 379 of file dom2_events.cpp.

long MouseEvent::screenY (  )  const

The vertical coordinate at which the event occurred relative to the origin of the screen coordinate system.

Definition at line 387 of file dom2_events.cpp.

bool MouseEvent::shiftKey (  )  const

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

Definition at line 419 of file dom2_events.cpp.
