Detailed Description

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.
