QTableView Question

[Gundi]

I have a tableview and am loading the model based from data from a database. That is why I used the view instead of a tablewidget. The challenge is I can't seem to be able to get a particular cell value from the view. What I am trying to accomplish with the View is essentially this code in the TableWidget. The user selects a cell and I want to grab the string data. Seems simple but for some reason I can't seem to figure it out.

Here is the equivalent code for the TableWidget I am trying to accomplish.
@
QList<QTableWidgetItem*> selectedRow = ui->tblRemoveTableLogList->selectedItems();
if(!selectedRow.isEmpty())
{
QString cellValue = selectedRow.at(0)->text();
return cellValue.toInt();
}
@

Any help is appreciated.

The Challenge is setModel() in QTableWidget is private and I need to set the model from the Database. Any ideas?

Hi,

You can use the QSelectionModel::selectedIndexes and from there get the text.

Hope it helps

I was trying that but could not seem to get the data out of the QModelIndexList. Where is the actual data stored in this class? Or how do I access it? I believe this list is a 1-N rows of data selected, but can't seem to get to a specific cell data.

Hi,

When the selection model is changed, you can be notified through the signal QItemSelectionModel::selectionChanged ( const QItemSelection & selected, const QItemSelection & deselected )

Then, you access selected indexes with QItemSelection::indexes()

@QModelIndexList indexes = theItemSelection.indexes();
foreach (QModelIndex index, indexes)
{
QString selectedItemAsString = index.data().toString();
}@

Thanks Seb. I must be missing something because there is no signal selectionChanged in QTableView

selectionChanged() is inherited from QAbstractItemView
