详细描述
The QTextObject class is a base class for different kinds of objects that can group parts of a QTextDocument together.
The common grouping text objects are lists (QTextList), frames (QTextFrame), and tables (QTextTable). A text object has an associated format() and document().
There are essentially two kinds of text objects: those that are used with blocks (block formats), and those that are used with characters (character formats). The first kind are derived from QTextBlockGroup, and the second kind from QTextFrame.
You rarely need to use this class directly. When creating custom text objects, you will also need to reimplement QTextDocument::createObject() which acts as a factory method for creating text objects.
参见 QTextDocument and Text Object Example.
成员函数
[protected] QTextObject::QTextObject(QTextDocument *document)
Creates a new QTextObject for the given document.
Warning: This function should never be called directly, but only from QTextDocument::createObject().
[protected] QTextObject::~QTextObject()
Destroys the text object.
Warning: Text objects are owned by the document, so you should never destroy them yourself.
QTextDocument *QTextObject::document() const
Returns the document this object belongs to.
参见 format().
QTextFormat QTextObject::format() const
Returns the text object's format.
参见 setFormat() and document().
int QTextObject::formatIndex() const
Returns the index of the object's format in the document's internal list of formats.
参见 QTextDocument::allFormats().
int QTextObject::objectIndex() const
Returns the object index of this object. This can be used together with QTextFormat::setObjectIndex().
[protected] void QTextObject::setFormat(const QTextFormat &format)
Sets the text object's format.
参见 format().
