DESCRIPTION
The QStyleSheetItem class provides an encapsulation of a set of text styles.

A style sheet item consists of a name and a set of attributes that specifiy its font, color, etc. When used in a style sheet (see styleSheet()), items define the name() of a rich text tag and the display property changes associated with it.

The display mode attribute indicates whether the item is a block, an inline element or a list element; see setDisplayMode(). The treatment of whitespace is controlled by the white space mode; see setWhiteSpaceMode(). An item's margins are set with setMargin(), In the case of list items, the list style is set with setListStyle(). An item may be a hypertext link anchor; see setAnchor(). Other attributes are set with setAlignment(), setVerticalAlignment(), setFontFamily(), setFontSize(), setFontWeight(), setFontItalic(), setFontUnderline(), setFontStrikeOut and setColor().

  Member Type Documentation

QStyleSheetItem::DisplayMode
This enum type defines the way adjacent elements are displayed.

QStyleSheetItem::DisplayBlock - elements are displayed as a rectangular block (e.g. <p>...</p>).

QStyleSheetItem::DisplayInline - elements are displayed in a horizontally flowing sequence (e.g. <em>...</em>).

QStyleSheetItem::DisplayListItem - elements are displayed in a vertical sequence (e.g. <li>...</li>).

QStyleSheetItem::DisplayNone - elements are not displayed at all.

QStyleSheetItem::ListStyle
This enum type defines how the items in a list are prefixed when displayed.

QStyleSheetItem::ListDisc - a filled circle (i.e. a bullet)

QStyleSheetItem::ListCircle - an unfilled circle

QStyleSheetItem::ListSquare - a filled square

QStyleSheetItem::ListDecimal - an integer in base 10: 1, 2, 3, ...

QStyleSheetItem::ListLowerAlpha - a lowercase letter: a, b, c, ...

QStyleSheetItem::ListUpperAlpha - an uppercase letter: A, B, C, ...

QStyleSheetItem::Margin

QStyleSheetItem::MarginLeft - left margin

QStyleSheetItem::MarginRight - right margin

QStyleSheetItem::MarginTop - top margin

QStyleSheetItem::MarginBottom - bottom margin

QStyleSheetItem::MarginAll - all margins (left, right, top and bottom)

QStyleSheetItem::MarginVertical - top and bottom margins

QStyleSheetItem::MarginHorizontal - left and right margins

QStyleSheetItem::MarginFirstLine - margin (indentation) of the first line of a paragarph (in addition to the MarginLeft of the paragraph)

QStyleSheetItem::VerticalAlignment
This enum type defines the way elements are aligned vertically. This is only supported for text elements.

QStyleSheetItem::VAlignBaseline - align the baseline of the element (or the bottom, if the element doesn't have a baseline) with the baseline of the parent

QStyleSheetItem::VAlignSub - subscript the element

QStyleSheetItem::VAlignSuper - superscript the element

QStyleSheetItem::WhiteSpaceMode
This enum defines the ways in which QStyleSheet can treat whitespace.

QStyleSheetItem::WhiteSpaceNormal - any sequence of whitespace (including line-breaks) is equivalent to a single space.

QStyleSheetItem::WhiteSpacePre - whitespace must be output exactly as given in the input.

QStyleSheetItem::WhiteSpaceNoWrap - multiple spaces are collapsed as with WhiteSpaceNormal, but no automatic line-breaks occur. To break lines manually, use the <br> tag.

MEMBER FUNCTION DOCUMENTATION

QStyleSheetItem::QStyleSheetItem ( QStyleSheet * parent, const TQString & name )
Constructs a new style called name for the stylesheet parent.

All properties in QStyleSheetItem are initially in the "do not change" state, except display mode, which defaults to DisplayInline.

QStyleSheetItem::QStyleSheetItem ( const QStyleSheetItem & other )
Copy constructor. Constructs a copy of other that is not bound to any style sheet.

QStyleSheetItem::~QStyleSheetItem ()
Destroys the style. Note that QStyleSheetItem objects become owned by QStyleSheet when they are created.

int QStyleSheetItem::alignment () const
Returns the alignment of this style. Possible values are AlignAuto, AlignLeft, AlignRight, AlignCenter or AlignJustify.

See also setAlignment() and TQt::AlignmentFlags.

bool QStyleSheetItem::allowedInContext ( const QStyleSheetItem * s ) const
Returns true if this style can be nested into an element of style s; otherwise returns false.

See also contexts() and setContexts().

TQColor QStyleSheetItem::color () const
Returns the text color of this style or an invalid color if no color has been set.

See also setColor() and TQColor::isValid().

TQString QStyleSheetItem::contexts () const
Returns a space-separated list of names of styles that may contain elements of this style. If nothing has been set, contexts() returns an empty string, which indicates that this style can be nested everywhere.

See also setContexts().

bool QStyleSheetItem::definesFontItalic () const
Returns true if the style defines a font shape; otherwise returns false. A style does not define any shape until setFontItalic() is called.

See also setFontItalic() and fontItalic().

bool QStyleSheetItem::definesFontStrikeOut () const
Returns true if the style defines a setting for the strikeOut property of the font; otherwise returns false. A style does not define this until setFontStrikeOut() is called.

See also setFontStrikeOut() and fontStrikeOut().

bool QStyleSheetItem::definesFontUnderline () const
Returns true if the style defines a setting for the underline property of the font; otherwise returns false. A style does not define this until setFontUnderline() is called.

See also setFontUnderline() and fontUnderline().

DisplayMode QStyleSheetItem::displayMode () const
Returns the display mode of the style.

See also setDisplayMode().

TQString QStyleSheetItem::fontFamily () const
Returns the font family setting of the style. This is either a valid font family or TQString::null if no family has been set.

See also setFontFamily(), QFont::family(), and QFont::setFamily().

bool QStyleSheetItem::fontItalic () const
Returns true if the style sets an italic font; otherwise returns false.

See also setFontItalic() and definesFontItalic().

int QStyleSheetItem::fontSize () const
Returns the font size setting of the style. This is either a valid point size or QStyleSheetItem::Undefined.

See also setFontSize(), QFont::pointSize(), and QFont::setPointSize().

bool QStyleSheetItem::fontStrikeOut () const
Returns true if the style sets a strike out font; otherwise returns false.

See also setFontStrikeOut() and definesFontStrikeOut().

bool QStyleSheetItem::fontUnderline () const
Returns true if the style sets an underlined font; otherwise returns false.

See also setFontUnderline() and definesFontUnderline().

int QStyleSheetItem::fontWeight () const
Returns the font weight setting of the style. This is either a valid QFont::Weight or the value QStyleSheetItem::Undefined.

See also setFontWeight() and QFont.

bool QStyleSheetItem::isAnchor () const
Returns whether this style is an anchor.

See also setAnchor().

int QStyleSheetItem::lineSpacing () const
This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

Returns the linespacing

ListStyle QStyleSheetItem::listStyle () const
Returns the list style of the style.

See also setListStyle() and ListStyle.

int QStyleSheetItem::logicalFontSize () const
Returns the logical font size setting of the style. This is either a valid size between 1 and 7 or QStyleSheetItem::Undefined.

See also setLogicalFontSize(), setLogicalFontSizeStep(), QFont::pointSize(), and QFont::setPointSize().

int QStyleSheetItem::logicalFontSizeStep () const
Returns the logical font size step of this style.

The default is 0. Tags such as big define +1; small defines -1.

See also setLogicalFontSizeStep().

int QStyleSheetItem::margin ( Margin m ) const
Returns the width of margin m in pixels.

The margin, m, can be MarginLeft, MarginRight, MarginTop, MarginBottom, or MarginFirstLine.

See also setMargin() and Margin.

TQString QStyleSheetItem::name () const
Returns the name of the style item.

int QStyleSheetItem::numberOfColumns () const

Returns the number of columns for this style.

See also setNumberOfColumns(), displayMode(), and setDisplayMode().

QStyleSheetItem & QStyleSheetItem::operator= ( const QStyleSheetItem & other )
Assignment. Assings a copy of other that is not bound to any style sheet. Unbounds first from previous style sheet.

bool QStyleSheetItem::selfNesting () const
Returns true if this style has self-nesting enabled; otherwise returns false.

See also setSelfNesting().

void QStyleSheetItem::setAlignment ( int f )
Sets the alignment to f. This only makes sense for styles with a display mode of DisplayBlock. Possible values are AlignAuto, AlignLeft, AlignRight, AlignCenter or AlignJustify.

See also alignment(), displayMode(), and TQt::AlignmentFlags.

void QStyleSheetItem::setAnchor ( bool anc )
If anc is true, sets this style to be an anchor (hypertext link); otherwise sets it to not be an anchor. Elements in this style link to other documents or anchors.

void QStyleSheetItem::setFontUnderline ( bool underline )
If underline is true, sets underline for the style; otherwise sets no underline.

See also fontUnderline() and definesFontUnderline().

void QStyleSheetItem::setFontWeight ( int w )
Sets the font weight setting of the style to w. Valid values are those defined by QFont::Weight.

See also QFont and fontWeight().

void QStyleSheetItem::setListStyle ( ListStyle s )
Sets the list style of the style to s.

This is used by nested elements that have a display mode of DisplayListItem.

See also listStyle(), DisplayMode, and ListStyle.

void QStyleSheetItem::setLogicalFontSize ( int s )
Sets the logical font size setting of the style to s. Valid logical sizes are 1 to 7.

See also logicalFontSize(), QFont::pointSize(), and QFont::setPointSize().

void QStyleSheetItem::setLogicalFontSizeStep ( int s )

This makes sense only if the style uses a block display mode (see QStyleSheetItem::DisplayMode).

See also numberOfColumns().

void QStyleSheetItem::setSelfNesting ( bool nesting )
Sets the self-nesting property for this style to nesting.

In order to support "dirty" HTML, paragraphs <p> and list items <li> are not self-nesting. This means that starting a new paragraph or list item automatically closes the previous one.

See also selfNesting().

void QStyleSheetItem::setVerticalAlignment ( VerticalAlignment valign )
Sets the vertical alignment to valign. Possible values are VAlignBaseline, VAlignSub or VAlignSuper.

The vertical alignment property is not inherited.

See also WhiteSpaceMode.

QStyleSheet * QStyleSheetItem::styleSheet ()
Returns the style sheet this item is in.

const QStyleSheet * QStyleSheetItem::styleSheet () const
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Returns the style sheet this item is in.

VerticalAlignment QStyleSheetItem::verticalAlignment () const
Returns the vertical alignment of the style. Possible values are VAlignBaseline, VAlignSub or VAlignSuper.

See also setVerticalAlignment().
