Add new item in ListView through С++ code
-
I want to add now Item in ListView through С++ code, with a check for originality.
I do it like this:
But code do not add new item, and change old item. (it see in debugger).
What have I done wrong? -
A couple of things:
- You should probably derive your DataList class from QAbstractListModel rather than QObject - it's made to do what you want here
- When adding items to your DataList, make sure to call beginInsertRows before and endInsertRows after.

Thanks.
QAbstractLIstModel helpedBut I still unclear why my code doesn't work
-
I used this in my code:
bool ImageModel::addImage(QString id, QString description, int duration_secs) { beginInsertRows(QModelIndex(), m_imageList.count(), m_imageList.count()); StructImage struct_image; m_imageList << struct_image; endInsertRows(); return true; }
hope it helps!
