[Solved] QTableView (QTableWidget) removeRow removes several rows

[Fatuo]

I have this code:

@
self.connect(table, SIGNAL('cellPressed(int, int)'), self.deleteRowClicked)
....
def deleteRowClicked(self, row, column):
if column == 0:
table = self.sender()
table.removeRow(row)
return True

@

So if the user clicks on the cell of the first column the row is removed.

The problem I have is that this code remove not only that row, also all rows behind it. :?

What I'm doing bad???

Hi and welcome to devnet,

Are you sure your slot is not called twice rather than removing two rows ?

[Fatuo]

Yes it is called, not twice, several times! , why???

[SGaist]

Right now, I don't know. Did you check the row/col values ? Are you keeping the mouse down when pressing your mouse button ?

[Fatuo]

Tried to do it for several ways, in one table the event is called twice, by the other hand a similar table, the event is called like ten times.

:????

Might be propagating to the next cell since you delete the one under the cursors (that's just an idea nothing more)

Personally, I wouldn't use cellPressed to delete a row, rather cellClicked or cellDoubleClicked.

I finally found the problem, the connect method was called each time a row is add to the TableWidget, so when the signal arrives the slot is called once per connect.

That's a classic :)

Most of the time connections like this one should be done in the widget's constructor

Still working wit QT designer so the constructor is changing frecuently. On the final version i will put it there all the connections.
