You could connect all of your buttons to a slot with no parameters and then get the position of the sender in this steps: <ol> <li>Cast the sender <code>QObject</code> to a QWidget via <code>qobject_cast</code></li> <li>Retrieve the index of that <code>QWidget</code> using <code>QLayout::indexOf(QWidget *widget)</code></li> <li>Then get the row, column, column span and row span with the <code>QGridLayout::getItemPosition(int index, int *row, int *column, int *rowSpan, int *columnSpan)</code></li> </ol> The example code would look like this: <pre><code>void MyWidgetWithAllLabels::commonSlot() { QWidget *buttonWidget = qobject_cast<QWidget*>(sender()); if (!buttonWidget) return; int indexOfButton = ui->gridLayout->indexOf(buttonWidget); int rowOfButton, columnOfButton, rowSpanOfButton, columnSpanOfButton; ui->gridLayout->getItemPosition(indexOfButton, &rowOfButton, &columnOfButton, &rowSpanOfButton, &columnSpanOfLabel); // Now you can get a reference to that specific QPushButton QLayoutItem *item = ui->gridLayout->itemAtPosition(rowOfButton, columnOfButton); QPushButton *clickedButton = qobject_cast<QPushButton*>(item->widget()); if (!clickedButton) return; // ... do something with that clickedButton } </code></pre> Referring to the code in your related post, you can connect your buttons to that slot like this: <pre><code>connect( ui->tile_0_0, SIGNAL(clicked()), this, SLOT(commonSlot())); connect( ui->tile_0_1, SIGNAL(clicked()), this, SLOT(commonSlot())); // ... </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
