Custom model item deletion (Qt4.4)

[bunjee]

Here is my custom model delete item function:

/*virtual */ void ZeBaseModel::RemoveItem(ZeBaseItem & item)
{
	int index;
	if ((index = mItems.indexOf(&item)) == -1) return;
 
	mItems.remove(index);
 
	RefreshView();
 
        // If I don't call this one I get random crashes
	if (mItems.size() == 0)
	{
		reset();
	}
 
	item.deleteLater();
}

/*virtual */ void ZeBaseModel::RemoveItem(ZeBaseItem & item)
{
	int index;
	if ((index = mItems.indexOf(&item)) == -1) return;

	mItems.remove(index);

	RefreshView();

        // If I don't call this one I get random crashes
	if (mItems.size() == 0)
	{
		reset();
	}

	item.deleteLater();
}

To copy to clipboard, switch view to plain text mode 

When I don't call reset when my Model delete his last item I get random crashes in my view.
What signal or function am I supposed to call to notify the view that an item has been deleted ?

You need to call beginRemoveRows() and endRemoveRows() on the model in appropriate places.
