Descripción detallada

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().

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

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

Documentación del constructor y destructor

QStyleSheetItem::QStyleSheetItem	(	QStyleSheet *	parent,
		const QString &	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.

		const QString &	name
	)

QStyleSheetItem::QStyleSheetItem ( const QStyleSheetItem & )

QStyleSheetItem::~QStyleSheetItem ( )
