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 () 和 fromHtml ().
The contents of a document fragment can be obtained as raw text by using the toRawText () function, as ASCII with toPlainText (), as HTML with toHtml (), or as Markdown with toMarkdown ().
构造空的 QTextDocumentFragment。
另请参阅 isEmpty ().
[explicit]
QTextDocumentFragment::
QTextDocumentFragment
(const
QTextDocument
*
document
)
转换给定 document into a QTextDocumentFragment. Note that the QTextDocumentFragment only stores the document contents, not meta information like the document's title.
[explicit]
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.

销毁文档片段。

QTextDocumentFragment
QTextDocumentFragment::
fromHtml
(const
QString
&
text
, const
QTextDocument
*
resourceProvider
= nullptr)
返回 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 .

QTextDocumentFragment
QTextDocumentFragment::
fromMarkdown
(const
QString
&
markdown
,
QTextDocument::MarkdownFeatures
features
= QTextDocument::MarkdownDialectGitHub)
返回 QTextDocumentFragment based on the given markdown text with the specified features 。默认为 GitHub 方言。
The formatting is preserved as much as possible; for example,
**bold**
will become a document fragment containing the text "bold" with a bold character style.
注意： Loading external resources is not supported.
该函数在 Qt 6.4 引入。

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.
返回
true
if the fragment is empty; otherwise returns
false
.
Returns the contents of the document fragment as HTML.

[since 6.4]
QString
QTextDocumentFragment::
toMarkdown
(
QTextDocument::MarkdownFeatures
features
= QTextDocument::MarkdownDialectGitHub) const
Returns the contents of the document fragment as Markdown, with the specified features 。默认为 GitHub 方言。
该函数在 Qt 6.4 引入。
另请参阅 toPlainText () 和 QTextDocument::toMarkdown ().
此函数返回如同 toRawText (), but will replace some unicode characters with ASCII alternatives. In particular, no-break space (U+00A0) is replaced by a regular space (U+0020), and both paragraph (U+2029) and line (U+2028) separators are replaced by line feed (U+000A). If you need the precise contents of the document, use toRawText () 代替。

QString
QTextDocumentFragment::
toRawText
() const
Returns the document fragment's text as raw text (i.e. with no formatting information).
该函数在 Qt 6.4 引入。
