Removing Rows from the QAbstractListModel , which is populated to QML.

[basha92]

Hi ALL,

I am able to populated items to QML from Qt using QAbstractListModel.
When i am trying to clear items from the QHash<QString, QString> Results;
using following function it is not getting reflected on the QML.

@void AutoIdentViewModel::clear()
{
beginRemoveRows(QModelIndex(), 0, Results.size());
identResults.clear();
endRemoveRows();--
}@

I am calling above function before inserting items in to the model in C++.
This function is called when i navigate from one page to another.

Where am i doing wrong ?

Hi,

AFAIK, if you are using beginRemoveRows then you need to do it in removeRows(). Something like this
@
bool ListModel::removeRows(int row, int count, const QModelIndex &index)
{
beginRemoveRows(index, row, row + count - 1);
identResults.clear();
endRemoveRows();
return true;
}
@

Another way would be to use beginResetModel()
@
bool ListModel::clearAll()
{
beginResetModel();
identResults.clear();
endResetModel();
return true;
}
