QModelIndexList access reading violation

Hi,
i have a table view in my application and I want remove the element selected.
This is my code:

Code:

---

QTableView tableView;
 
QItemSelectionModel * m_pxSelectionModel;
QModelIndexList indexes;
QModelIndex index;
 
if (m_pxSelectionModel != NULL)
	{
		m_pxSelectionModel = NULL;
	}
 
	m_pxSelectionModel = tableView->selectionModel();
 
	qDebug() << "List" << indexes;
	if (indexes.isEmpty())
	{
		indexes = m_pxSelectionModel->selectedRows();
	}else{
		indexes.clear();
	}
 
	for (int j = 0; j < indexes.size(); j++)
	{
		index = indexes.at(j);
		int row = index.row();
		model->removeRows(row, 1, QModelIndex());
	}

---

At the first time work correctly and the selected row is cancelled. At the second time I have a problem: this is the message error:

List (QModelIndex(0,0,0x71b2580,QStandardItemModel(0x37 fbff0) ) , QModelIndex(0,1,0x71b2580,QStandardItemModel(0x37f bff0) ) , QModelIndex(0,2,0x71b2580,QStandardItemModel(0x37f bff0) ) )
First-chance exception at 0x76f5e23e in Test.exe: 0xC0000005: Access violation reading location 0x681012a8.
Unhandled exception at 0x76f5e23e in Test.exe: 0xC0000005: Access violation reading location 0x681012a8.


Can anyone help me please??

Thanks, bye

Some idea??

The obvious:

• Have you single-stepped it in your debugger?
• Which line causes the access violation?
• Is the model pointer valid at line 26?

Other questions that might help;

• Why are you doing the conditional dance with lines 7-10 and 15-20? Do you want the selection model and the rows or not?
• How is it that indexes has something in it at line 14 before you initialise it at line 17 (sometimes)?
• Are other model indexes in the list still valid after you delete a row?
• Are you sure all the selected indexes have an invalid parent at line 26 (i.e. is the model a table model or a tree)?

I have solved reimplementing my procedure and saving a pointer to the current item selected in the main table.

Thanks for the reply, Bye
