DESCRIPTION
This class is used for an HTML::DOM object's 'default view.' It implements the AbstractView DOM interface.It is an inside-out class, so you can subclass it without being constrained to any particular object structure.
METHODS
Methods that HTML::DOM::View itself implements
- $view->document
- Returns the document associated with the view.
You may pass an argument to set it, in which case the old value is returned. This attribute holds a weak reference to the object.
- $view->getComputedStyle( $elem )
- $view->getComputedStyle( $elem, $pseudo_elem )
- Returns the computed style as a CSS::DOM::Style object. $pseudo_elem is the name of the pseudo-element, with or without the initial colons (1 or 2).
Subclass methods that HTML::DOM::View uses
- $view->ua_style_sheet( $string )
- $view->user_style_sheet( $string )
- These are called by "getComputedStyle" and are expected to return the user agent and user style sheets, respectively, as CSS::DOM objects.
