54 \class QQuickTextDocument -

55 \since 5.1 -

56 \brief The QQuickTextDocument class provides access to the QTextDocument of QQuickTextEdit. -

57 \inmodule QtQuick -

58 -

59 This class provides access to the QTextDocument of QQuickTextEdit elements. -

60 This is provided to allow usage of the \l{Rich Text Processing} functionalities of Qt. -

61 You are not allowed to modify the document, but it can be used to output content, for example with \l{QTextDocumentWriter}), -

62 or provide additional formatting, for example with \l{QSyntaxHighlighter}. -

63 -

64 The class has to be used from C++ directly, using the property of the \l TextEdit. -

65 -

66 Warning: The QTextDocument provided is used internally by \l {Qt Quick} elements to provide text manipulation primitives. -

67 You are not allowed to perform any modification of the internal state of the QTextDocument. If you do, the element -

68 in question may stop functioning or crash. -
