Подробное описание
The QTextDocumentFragment class represents a piece of formatted text from a QTextDocument.
A QTextDocumentFragment is a fragment of rich text, that can be inserted into a QTextDocument. A document fragment can be created from a QTextDocument, from a QTextCursor's selection, or from another document fragment. Document fragments can also be created by the static functions, fromPlainText() and fromHtml().
The contents of a document fragment can be obtained as plain text by using the toPlainText() function, or it can be obtained as HTML with toHtml().
Описание функций-членов
QTextDocumentFragment::QTextDocumentFragment ()
Constructs an empty QTextDocumentFragment.
Смотрите также isEmpty().
QTextDocumentFragment::QTextDocumentFragment ( const QTextDocument * document )
Converts the given document into a QTextDocumentFragment. Note that the QTextDocumentFragment only stores the document contents, not meta information like the document's title.
QTextDocumentFragment::QTextDocumentFragment ( const QTextCursor & cursor )
Creates a QTextDocumentFragment from the cursor's selection. If the cursor doesn't have a selection, the created fragment is empty.
See also isEmpty() and QTextCursor::selection().
QTextDocumentFragment::QTextDocumentFragment ( const QTextDocumentFragment & other )
Copy constructor. Creates a copy of the other fragment.
QTextDocumentFragment::~QTextDocumentFragment ()
Destroys the document fragment.
QTextDocumentFragment QTextDocumentFragment::fromHtml ( const QString & text ) [static]
Returns a QTextDocumentFragment based on the arbitrary piece of HTML in the given text. The formatting is preserved as much as possible; for example, "<b>bold</b>" will become a document fragment with the text "bold" with a bold character format.
QTextDocumentFragment QTextDocumentFragment::fromHtml ( const QString & text, const QTextDocument * resourceProvider ) [static]
Это перегруженная функция, предоставленная для удобства.
Returns a QTextDocumentFragment based on the arbitrary piece of HTML in the given text. The formatting is preserved as much as possible; for example, "<b>bold</b>" will become a document fragment with the text "bold" with a bold character format.
If the provided HTML contains references to external resources such as imported style sheets, then they will be loaded through the resourceProvider.
Эта функция была введена в Qt 4.2.
QTextDocumentFragment QTextDocumentFragment::fromPlainText ( const QString & plainText ) [static]
Returns a document fragment that contains the given plainText.
When inserting such a fragment into a QTextDocument the current char format of the QTextCursor used for insertion is used as format for the text.
bool QTextDocumentFragment::isEmpty () const
Returns true if the fragment is empty; otherwise returns false.
QString QTextDocumentFragment::toHtml ( const QByteArray & encoding ) const
Returns the contents of the document fragment as HTML, using the specified encoding (e.g., "UTF-8", "ISO 8859-1").
Эта функция была введена в Qt 4.2.
See also toPlainText(), QTextDocument::toHtml(), and QTextCodec.
QString QTextDocumentFragment::toHtml () const
Это перегруженная функция, предоставленная для удобства.
QString QTextDocumentFragment::toPlainText () const
Returns the document fragment's text as plain text (i.e. with no formatting information).
See also toHtml().
QTextDocumentFragment & QTextDocumentFragment::operator= ( const QTextDocumentFragment & other )
Assigns the other fragment to this fragment.
