QTableView line edit clears the text on edit

Hi all.

Is there a way to alter the behavior of QTableView when editing a text cell to not clear the text in the cell when the cell is selected for editing?

For instance, I have a QTableView where the first column contains long text fields. It is impractical to have the user re-enter the entire contents just to change a single character.

I know I can do this by providing a custom widget for the column, but it seems like such standard behavior that there is a default implementation that I am missing.


Thanks!

That is strange. What did you set for view properties?

I have a table view like this:

Code:

---

model = new QSqlTableModel(this, logdb);
    view = new QTableView();
    view->setModel(model);
    model->setTable("log");
    header = new QHeaderView(Qt::Horizontal, this);
    view->setHorizontalHeader(header);
    header->setMovable(TRUE);

---

And when I click in a table cell to edit, it highlights the cell, then if I double click, it highlights just the text for editing. Nothing goes away.

Thanks for the quick reply.

So it should behave the way I want by default? Very strange.

Here's my code which sets up the view:

Code:

---

ui->tableView->setColumnWidth(0, 200);
	ui->tableView->setColumnWidth(1, 150);
	ui->tableView->verticalHeader()->hide();
	ui->tableView->horizontalHeader()->setStretchLastSection(true);
	ui->tableView->resizeColumnsToContents();
	ui->tableView->setSelectionMode(QAbstractItemView::SingleSelection);
	ui->tableView->setEditTriggers(QAbstractItemView::DoubleClicked);

---

I didn't see anything strange in there, but I tried commenting out all of the above and got the same behavior as before.

My platform is qt 4.6.2-1 running on kde 4.4.0. Do you think it could be a platform issue?

Thanks again.

I am currently seeing the same problem/behavior on Linux running Qt 4.5.3. The contents of an editable table cell are erased when the cell is selected. I would like them to remain untouched unless the user explictly deletes them.

Found a solution in this thread; add a clause to your model's data() routine that returns the item's data in editable form when called with a Qt::EditRole.

@SixDegrees:
Understandable that since this thread is old an answer to this request might go unspoken.
-Yet, do you have any example of the implementation you mentioned regarding the data() function in the model?
[currently experiencing a similar problem where the cell contents are deleted upon selection rather then inherently editable.
