How to use QTextListFormat?

Hi!
I am currently experimenting with the Qt Quick Text Editor and wanted to extend the example with a list function. But I do not understand the documentation and could not find an example on how QTextListFormat is used. Here is what I did so far:
// added to .h Q_PROPERTY(bool ul READ ul WRITE setUl NOTIFY ulChanged) public: bool ul() const; void setUl(bool ul); // added to .cpp bool DocumentHandler::ul() const { QTextCursor cursor = textCursor(); if (cursor.isNull()) return false; qDebug()<< "is list?" << cursor.blockFormat().isListFormat(); return cursor.blockFormat().isListFormat(); } void DocumentHandler::setUl(bool ul) { qDebug() << "ul is: " << ul; QTextCursor cursor = textCursor(); QTextListFormat list; if(ul){ list.setStyle(QTextListFormat::ListDisc); }else{ list.clearProperty(QTextListFormat::ListDisc); } cursor.insertList(list); emit ulChanged(); }
isListFormat always returns false. I guess I am not using it correctly. How can I check if the cursor is positioned in a list?
setUl works for setting a list. But the list is always started in a new line and in case the cursor has a selection the selected text is deleted. Also I guess unsetting the list is done wrong as well but there is nothing in the docs on how to remove a list format from a text block.
Could someone point me to some explanation?
