connect table cell to QLabel

jss193

Hello,

I have a QAbstractItemModel model where I create dynamically QLabels and rows by a pushButton, I am trying to connect text on column 0 to each QLabel, so that if I change for example text in position 0,1 QLabel labels[0] is automatically updated, I tried this:

for(int i=0;i<model->rowCount(QModelIndex());i++){
            QModelIndex idx = model->index(i,0);

            connect(model->data(idx),SIGNAL(textChanged(const QString &)),&labels[i],SLOT(changeText()));

        }

but it does not compiles, how could I solve this?

Thank you everyone!

but it does not compiles,

It fails to compile but does not show any error message?

The signatures of the signal and slot do not match.

Hi,

Why are you using QLabels rather than an a QListView to show these texts ?

From the looks of it, you are trying to connect QVariant objects which will not work.

@SGaist because I am adding dinamically qlabels that will be images not text.

You can either use the DecorationRole to show them or a custom QStyledItemDelegate
