[Qt-interest] QTreeView::rowsInserted internal representation of the model has been corrupted, resetting.

[venkateswarlu kareti]

Hi All

I am getting an error in using QTreeView With custom model.


I extended QAbstractItemModel and override rowsInsert() method.


In my public slot i am calling as

 
beginInsertRows(parentIndex,firstrow,firstrow) //i am inserting only one row
insertRow(firstrow,parentIndex);
endInsertRows();

emit dataChanged(parentIndex.child(firstrow,firstrow));//inserted one row

emit expand(parentIndex); 

//i want to expand the parent


insertRows(row,count,parentIndex) 

//implementation of insertrows
{
           TreeItem* parentItem = static_cast<TreeItem*> (parentIndex.internalPointer());
 TreeItem* childIten=new TreeItem(parentItem); //custom class to represent tree Item.
            parentItem->insertItem(row,childItem);//this will inset the child item in the childitems list of parentitem.
}

If i insert one item at a time it is fine.

If i insert bulk of items ,programatically, it is giving waring msg 

"QTreeView::rowsInserted internal representation of the model has been corrupted, resetting.". This is not for each file 9 times/500 files approximately. 


"How to get rid of this. Please Help me"
