Inherited by QTextBlockFormat, QTextCharFormat, QTextFrameFormat and QTextListFormat.
The QTextFormat class provides formatting information for a QTextDocument.
A QTextFormat is a generic class used for describing the format of parts of a QTextDocument. The derived classes QTextCharFormat, QTextBlockFormat, QTextListFormat, and QTextTableFormat are usually more useful, and describe the formatting that is applied to specific parts of the document.
A format has a FormatType which specifies the kinds of text item it can format; e.g. a block of text, a list, a table, etc. A format also has various properties (some specific to particular format types), as described by the Property enum. Every property has a corresponding Property.
The format type is given by type(), and the format can be tested with isCharFormat(), isBlockFormat(), isListFormat(), isTableFormat(), isFrameFormat(), and isImageFormat(). If the type is determined, it can be retrieved with toCharFormat(), toBlockFormat(), toListFormat(), toTableFormat(), toFrameFormat(), and toImageFormat().
A format's properties can be set with the setProperty() functions, and retrieved with boolProperty(), intProperty(), doubleProperty(), and stringProperty() as appropriate. All the property IDs used in the format can be retrieved with allPropertyIds(). One format can be merged into another using merge().
A format's object index can be set with setObjectIndex(), and retrieved with objectIndex(). These methods can be used to associate the format with a QTextObject. It is used to represent lists, frames, and tables inside the document.
