How to implement rich text logic on QML TextEdit with QSyntaxHighlighter class in Qt?

Question

I have a TextEdit in my QML file and I have a QSyntaxHighlighter C++ class. I want to specify the highlighting logic in the C++ class and apply it to the TextEdit, but I am not sure how to make the connection between the QML object and the C++ class. Can you also please provide some sample code? I couldn't find how to implement it with the Qt documentation.

Answer 1

You can use TextEdit::textDocument, which holds an instance of QQuickTextDocument, to gain access to the underlying QTextDocument that you can pass to QSyntaxHighlighter constructor.
