QTableWidget, one column editable

I want my tablewidget has these functionality:
1) one column can be editable, the rest not;
2) row select

I tried it out in this way:

Code:

---

tableWidget->horizontalHeader()->setClickable(false);
tableWidget->horizontalHeader()->setStretchLastSection(true);
tableWidget->setSelectionMode(QAbstractItemView::SingleSelection);
tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);

---

tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers ) will forbiden all the edition. I couldn't find out the correct method for enable edition only for on column. The method of setFlags() to TableWidgetItem with Qt::ItemIsEditable will disable the edition. I am confused. Any one can help? Thanks.

Hi,

It can be done by catching itemClicked or double clicked event.
Compare the column of clicked item and set the flag as editable or un-editable.

Firstly for all items you can set edig triggers as NoEditTriggers

hi
use 'void cellClicked ( int row, int column )' signal
and Put yor code in this signal,

for example:
first connect signal to table
ok
void MyClass::cellClickedMyTable(int _row, int _col){
if( _col == 2 ){
myTable->item( _row, _col )->setFlags(Qt::ItemIsEditable); // or another code
}
}

Thanks for your reply.

I am using your way to test it out.
I think it is working. But the 'Flag' thing is not working as I expected.

After set one cell with

Code:

---

myTable->item( _row, _col )->setFlags(Qt::ItemIsEditable);

---

this cell is actually not editable any more. I tried also with flag Qt::ItemIsSelectable, after setting this, the cell is not selectable. Is this totally working like this, or other things related to this parameter have conflicts with it?

What I expected is, after set it with ItemIsSelectable, the cell can be selected, isn't it? The testing result is something opposite....:(

After some search here, I found the answer:

Code:

---

void MyTableWidget::click_cell(int row, int column)
{
	if( column != 1 )
		tableWidget->item(row, column)->setFlags(tableWidget->item(row, column)->flags() & ~Qt::ItemIsEditable); 
}

---

:D

I used the above solution to make the cells uneditable except for a specific column. The problem now is that every click also triggers the following SIGNAL-SLOT

connect(ui->tableWidget, SIGNAL(itemChanged(QTableWidgetItem*)), this, SLOT(recalculate(QTableWidgetItem*)));

This causes the recalculation to occur on every click on a non-editable field. Any idea on how to stop this from happening? Is there a way to state which column the itemChanged SIGNAL will look at?

Thanks,

Pericles

EDIT* I found the solution by disconnecting the SIGNAL-SLOT right before the change and connecting again after the change.
