Deleting selected row from a QTableView

[ChrisW67]

Line 4 creates a new selection model rather than fetching the model that is already associated with the view. Line 5 does not do what you think it does: it deselects everything, it does not delete selected data. You want something like this (I haven't tested it so please forgive minor glitches):

void Loader::removeChannelFromTable()
{
    QMessageBox::information(this,tr(""),tr("Slot working?") ); // to make sure slot is being run.
 
    // code to get list of selected rows
    QItemSelectionModel *selected = channelsView->selectionModel();
    QModelIndexList rowList = selected->selectedRows();
 
    // code to delete these model indexes from the model
    foreach(QModelIndex rowIndex, rowList) {
        model->removeRow(roxIndex.row(), rowIndex.parent());
    }
}

void Loader::removeChannelFromTable()
{
    QMessageBox::information(this,tr(""),tr("Slot working?") ); // to make sure slot is being run.

    // code to get list of selected rows
    QItemSelectionModel *selected = channelsView->selectionModel();
    QModelIndexList rowList = selected->selectedRows();

    // code to delete these model indexes from the model
    foreach(QModelIndex rowIndex, rowList) {
        model->removeRow(roxIndex.row(), rowIndex.parent());
    }
}

To copy to clipboard, switch view to plain text mode 

You might also consider using QAbstractItemView::setSelectionBehavior() and QAbstractItemView::setSelectionMode() on the view so the user selects whole rows etc.
