Bug of bandedtable view?

6 years 2 months ago #1 by corrado valeri
I implemented a bandedTableView in order to manage complex informations.
If I click on a cell, I can get the Cell text with this code:
void Window::cellButtonClicked(CellButtonClickEventArgs* args)
{
    Qtitan::GridTableView* view = m_grid->view<Qtitan::GridTableView>();
    int row = args->row()->rowIndex();
    int col = args->column()->index();
    QVariant s = view->model()->data(view->model()->index(row,col),Qt::DisplayRole);
    QMessageBox::information(this, tr("Cell button clicked (new)"), 
                             tr("Clicked: Button - %1, Column Title - %2, RowIndex - %3 Data displayrole: %4").arg(args->buttonIndex()).arg(args->column()->caption()).arg(args->row()->rowIndex())
                             .arg(s.toString()));
}

Well, if I click on a column header to sort the datamodel, the code previuos quoted doesn't work any more..
The data returned are always referred to the UNSORTED datamodel.

Another problem: recently I see that answers from the official support are missing, there are old topics still without support answers: should I be worried?

thanks

The row in event's argument CellButtonClickEventArgs is a row of the grid (sorted, as you see on the screen). Not in model. To get row index in model related to this grid’s row please use GridRow::modelRowIndex().
In your case:
int row = args->row()->modelRowIndex();
