This class provides access to the QTextDocument of QQuickTextEdit elements. This is provided to allow usage of the 富文本处理 functionalities of Qt, including document modifications. It can also be used to output content, for example with QTextDocumentWriter , or provide additional formatting, for example with QSyntaxHighlighter .
[read-only, preliminary]
errorString
: const
QString
This property is under development and is subject to change.
This property holds a human-readable string describing the error that occurred during loading or saving, if any
By default this string is empty.
This property was introduced in Qt 6.7.

modified
:
bool
This property is under development and is subject to change.
此特性保持文档是否已被用户修改
This property holds whether the document has been modified by the user since the last time it was loaded or saved. By default, this property is
false
.
就像
QTextDocument::modified
, you can set the modified property: for example, set it to
false
to allow setting the
source
property to a different URL (thus discarding the user's changes).
This property was introduced in Qt 6.7.

source
:
QUrl
This property is under development and is subject to change.
This property holds the URL from which to load document contents
QQuickTextDocument can handle any text format supported by Qt, loaded from any URL scheme supported by Qt.
The
source
property cannot be changed while the document's
modified
state is
true
. If the user has modified the document contents, you should prompt the user whether to
save
(), or else discard changes by setting
modified
to
false
before setting the
source
property to a different URL.
This property was introduced in Qt 6.7.
