The Q3StyleSheetItem class provides an encapsulation of a set of text styles.
A style sheet item consists of a name and a set of attributes that specify its font, color, etc. When used in a 样式表 (见 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 ；见 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 ().
