Method Detail

getType

public java.lang.String getType()

Description copied from interface: StyleSheet

This specifies the style sheet language for this style sheet. The style sheet language is specified as a content type (e.g. "text/css"). The content type is often specified in the ownerNode. Also see the type attribute definition for the LINK element in HTML 4.0, and the type pseudo-attribute for the XML style sheet processing instruction.

Specified by:

getType in interface StyleSheet

getDisabled

public boolean getDisabled()

Description copied from interface: StyleSheet

false if the style sheet is applied to the document. true if it is not. Modifying this attribute may cause a new resolution of style for the document. A stylesheet only applies if both an appropriate medium definition is present and the disabled attribute is false. So, if the media doesn't apply to the current user agent, the disabled attribute is ignored.

Specified by:

getDisabled in interface StyleSheet

setDisabled

public void setDisabled(boolean disabled)

We will need to respond more fully if a stylesheet is disabled, probably by generating an event for the main application.

Specified by:

setDisabled in interface StyleSheet

setDisabledOnly

public void setDisabledOnly(boolean disabled)

getOwnerNode

public org.w3c.dom.Node getOwnerNode()

Description copied from interface: StyleSheet

The node that associates this style sheet with the document. For HTML, this may be the corresponding LINK or STYLE element. For XML, it may be the linking processing instruction. For style sheets that are included by other style sheets, the value of this attribute is null.

Specified by:

getOwnerNode in interface StyleSheet

getParentStyleSheet

public StyleSheet getParentStyleSheet()

Description copied from interface: StyleSheet

For style sheet languages that support the concept of style sheet inclusion, this attribute represents the including style sheet, if one exists. If the style sheet is a top-level style sheet, or the style sheet language does not support inclusion, the value of this attribute is null.

Specified by:

getParentStyleSheet in interface StyleSheet

getHref

public java.lang.String getHref()

Description copied from interface: StyleSheet

If the style sheet is a linked style sheet, the value of its attribute is its location. For inline style sheets, the value of this attribute is null. See the href attribute definition for the LINK element in HTML 4.0, and the href pseudo-attribute for the XML style sheet processing instruction.

Specified by:

getHref in interface StyleSheet

getTitle

public java.lang.String getTitle()

Description copied from interface: StyleSheet

The advisory title. The title is often specified in the ownerNode. See the title attribute definition for the LINK element in HTML 4.0, and the title pseudo-attribute for the XML style sheet processing instruction.

Specified by:

getTitle in interface StyleSheet

getMedia

public MediaList getMedia()

Description copied from interface: StyleSheet

The intended destination media for style information. The media is often specified in the ownerNode. If no media has been specified, the MediaList will be empty. See the media attribute definition for the LINK element in HTML 4.0, and the media pseudo-attribute for the XML style sheet processing instruction . Modifying the media list may cause a change to the attribute disabled.

Specified by:

getMedia in interface StyleSheet

getOwnerRule

public CSSRule getOwnerRule()

Description copied from interface: CSSStyleSheet

If this style sheet comes from an @import rule, the ownerRule attribute will contain the CSSImportRule. In that case, the ownerNode attribute in the StyleSheet interface will be null. If the style sheet comes from an element or a processing instruction, the ownerRule attribute will be null and the ownerNode attribute will contain the Node.

Specified by:

getOwnerRule in interface CSSStyleSheet

getCssRules

public CSSRuleList getCssRules()

Description copied from interface: CSSStyleSheet

The list of all CSS rules contained within the style sheet. This includes both rule sets and at-rules.

Specified by:

getCssRules in interface CSSStyleSheet

insertRule

public int insertRule(java.lang.String rule,
                      int index)
               throws org.w3c.dom.DOMException

Description copied from interface: CSSStyleSheet

Used to insert a new rule into the style sheet. The new rule now becomes part of the cascade.

Specified by:

insertRule in interface CSSStyleSheet

Parameters:

rule - The parsable text representing the rule. For rule sets this contains both the selector and the style declaration. For at-rules, this specifies both the at-identifier and the rule content.

index - The index within the style sheet's rule list of the rule before which to insert the specified rule. If the specified index is equal to the length of the style sheet's rule collection, the rule will be added to the end of the style sheet.

Returns:

The index within the style sheet's rule collection of the newly inserted rule.

Throws:

org.w3c.dom.DOMException - HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at the specified index e.g. if an @import rule is inserted after a standard rule set or other at-rule.
INDEX_SIZE_ERR: Raised if the specified index is not a valid insertion point.
NO_MODIFICATION_ALLOWED_ERR: Raised if this style sheet is readonly.
SYNTAX_ERR: Raised if the specified rule has a syntax error and is unparsable.

deleteRule

public void deleteRule(int index)
                throws org.w3c.dom.DOMException

Description copied from interface: CSSStyleSheet

Used to delete a rule from the style sheet.

Specified by:

Parameters:

index - The index within the style sheet's rule list of the rule to remove.

Throws:
