Detailed Description
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().
Member Function Documentation
QTextDocumentFragment::QTextDocumentFragment(const QTextDocumentFragment &other)
Copy constructor. Creates a copy of the other fragment.
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 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()
Constructs an empty QTextDocumentFragment.
See also isEmpty().
QTextDocumentFragment &QTextDocumentFragment::operator=(const QTextDocumentFragment &other)
Assigns the other fragment to this fragment.
QTextDocumentFragment::~QTextDocumentFragment()
Destroys the document fragment.
[static] QTextDocumentFragment QTextDocumentFragment::fromHtml(const QString &text, const QTextDocument *resourceProvider = nullptr)
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.
[static] QTextDocumentFragment QTextDocumentFragment::fromPlainText(const QString &plainText)
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
Returns the contents of the document fragment as HTML.
See also toPlainText() and QTextDocument::toHtml().
QString QTextDocumentFragment::toPlainText() const
Returns the document fragment's text as plain text (i.e. with no formatting information).
See also toHtml().
