NAME
Mozilla::DOM::KeyEvent
DESCRIPTION
The second argument of GtkMozEmbed's dom_key_* signal handlers will be a Mozilla::DOM::KeyEvent object, which is a wrapper around an instance of Mozilla's nsIDOMKeyEvent interface. This inherits from UIEvent.
Note: although <DOMImplementation|Mozilla::DOM::DOMImplementation>'s HasFeature('KeyEvents', '2.0') (and '3.0' and '') claimed (on my system) that KeyEvents were not supported, I found that you can in fact do key events.
The following constants are available to be compared with "GetKeyCode". You can access these either through the (mouse or key) event object, like $event->DOM_VK_TAB, export them all with use Mozilla::DOM::KeyEvent qw(:keycodes)
, or export them individually.
- DOM_VK_CANCEL
- DOM_VK_HELP
- DOM_VK_BACK_SPACE
- DOM_VK_TAB
- DOM_VK_CLEAR
- DOM_VK_RETURN
- DOM_VK_ENTER

- DOM_VK_CONTROL
- DOM_VK_ALT
- DOM_VK_PAUSE
- DOM_VK_CAPS_LOCK
- DOM_VK_ESCAPE
- DOM_VK_SPACE
- DOM_VK_PAGE_UP

- DOM_VK_END
- DOM_VK_HOME
- DOM_VK_LEFT
- DOM_VK_UP
- DOM_VK_RIGHT

- DOM_VK_x, where x = 0 - 9
- DOM_VK_SEMICOLON
- DOM_VK_EQUALS
- DOM_VK_x, where x = A - Z
- DOM_VK_CONTEXT_MENU
- DOM_VK_NUMPADx, where x = 0 - 9
- DOM_VK_MULTIPLY
- DOM_VK_ADD
- DOM_VK_SEPARATOR
- DOM_VK_SUBTRACT
- DOM_VK_DECIMAL

- DOM_VK_QUOTE
- DOM_VK_META
CLASS METHODS
$iid = Mozilla::DOM::KeyEvent->GetIID()
Pass this to QueryInterface.
METHODS
$bool = $event->GetAltKey
This function returns true if the Alt key was held down when the key event occured. (Note: I found this to not be strictly true.)
$char_code = $event->GetCharCode
This function gets the character code, which is the Unicode number representing that character (e.g. 'a' is 97). For example, you could pass this number to the `chr' function in Perl.
$bool = $event->GetCtrlKey
This function returns true if the Ctrl key was held down when the key event occured.
$key_code = $event->GetKeyCode
This function gets the key code for "special" keys, such as the function keys (e.g., F3), caps lock, right arrow, etc.
$bool = $event->GetMetaKey
This function returns true if the Meta key was held down when the key event occured.
$bool = $event->GetShiftKey
This function returns true if the Shift key was held down when the key event occured.
$event->InitKeyEvent($eventType, $canbubble, $cancelable, $ctrlkey, $altkey, $shiftkey, $metakey, $keycode, $charcode)
$eventtype (string)
$canbubble (boolean)
$cancelable (boolean)
$ctrlkey (boolean)
$altkey (boolean)
$shiftkey (boolean)
$metakey (boolean)
$keycode (integer (long))
$charcode (integer (long))
See Event::InitEvent for more information. This method is basically the same as InitEvent, but with six (seven normally) extra arguments. (XXX: add docs for args)
Note: I don't see how you can Create or QueryInterface an AbstractView, and trying to pass in 0
or undef
was just causing a segfault, so I've omitted what would normally be the 4th argument of this method. If someone can explain why you'd need it and how you'd use it, then I can put it back in.
