QTJambi: QAbstractItemModel.SetData is not called

Palikur

Hi,

I'm developing a very simple table view on QtJambi using a model/view implementation. My QTableView is configured as follows:

    partTabView = new QTableView(gridLayoutWidget);
    partTabView.setObjectName("partTabView");
    partTabView.setSortingEnabled(true);
    partTabView.setSelectionBehavior(QAbstractItemView.SelectionBehavior.SelectRows);
    partTabView.setSelectionMode(QAbstractItemView.SelectionMode.SingleSelection);
    partTabView.setHorizontalScrollBarPolicy(Qt.ScrollBarPolicy.ScrollBarAlwaysOff);
    partTabView.setEditTriggers(EditTrigger.AllEditTriggers);
    
    
    partdata = new ParticipantModel(gd);
    partTabView.setModel(partdata);
    partTabView.itemDelegate().commitData.connect(this, "on_action_Edit_Part(QWidget)");

    partdata.dataChanged.connect(this, "on_data_changed(QModelIndex, QModelIndex)");

And on the model size I have the following flags and setData definitions in my model:

public final Qt.ItemFlags flags(QModelIndex index)
{
	Qt.ItemFlags flags = new Qt.ItemFlags(Qt.ItemFlag.ItemIsEnabled);
	
    if (!isIndexValid(index)) {
    	return flags;
    }
    flags = super.flags(index);
    
    flags.set(Qt.ItemFlag.ItemIsSelectable);
    flags.set(Qt.ItemFlag.ItemIsEditable);
    
    return flags;
}

public final boolean setData(QModelIndex index, QObject value, int role)
{
	if (!isIndexValid(index))
		return false;
	
    // Check Role
	if (role == Qt.ItemDataRole.EditRole)
	{
    	List<String> l = m_gridData.get(index.row());
    	l.set(index.column(), value.toString());
    	m_gridData.set(index.row(), l);
    	dataChanged.emit(index, index);
	}
	return true;
}

I have neither any custom delegate nor editor, I'm using the default ones from QTableView. I manage to insert/remove and edit the cells but I cannot update their contents. The initial set values are always replacing the ones I type. Actually, the setData function is never called. As far as I understand, the default itemdelegate implements a "setModelData" function which automatically calls the setData function on the model so I don't need to call it myself. Am I missing something?

Finally, upon edition of the cells (Return key pressed) my slot "on_action_Edit_Part(QWidget)" is properly called. I could call partdata.setData from there but I don't know how to retrieve the index and the typed data from the Editor.

Dummy me...the setData signature was wrong...it has to be:

public final boolean setData(QModelIndex index, Object value, int role)
