Qt Qtableview not getting signal for header item clicking.

Question

Hi ,

Am using Qtableview with QsqlTableModel for populating a table data. I want to sort the column based on user selection on column header.

i tried the way mentioned in http://stackoverflow.com/questions/3081340/qtableview-sorting-signal for getting the signal. (get the horizontal header from QtableView and connect signal sectionclicked(int logical index)

But the same signal is not getting emitted when i click on column header.

please find the code where connection is done

member variable

QHeaderView *m_horiz_header;

.cpp file

m_sqltablemodel->setTable(tabel_name);
m_sqltablemodel->setEditStrategy(QSqlTableModel::OnManualSubmit);
m_sqltablemodel->select();

m_horiz_header= m_table_view->horizontalHeader();
connect(m_horiz_header, SIGNAL(sectionClicked ( int logicalIndex ) ),
    this, SLOT(on_sectionClicked ( int logicalIndex ) ));

slot function for sorting

void class::on_sectionClicked ( int logicalIndex ) {

m_horiz_header->setSortIndicator(logicalIndex, Qt::AscendingOrder);
m_table_view->sortByColumn(logicalIndex);

}

This function is not getting called, when column header is clicked.

Can you please help me how to do this, where i went wrong?

Thanks in advance.

Answer 1

I got the reasong why the signal connection is failed.

argument name should not be mentioned on connect.

connect(m_horiz_header, SIGNAL(sectionClicked ( int ) ), this, SLOT(on_sectionClicked ( int ) ));

by modifiying the above code like this, it got worked.
