How to use QTextListFormat?

D_Tec

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?
