    I report a bug in Qt bug tracker for this.

    I want my header to be changed depends on the row I clicked (for ex: if I click on a even row (index.row()%2 == 0 ) I put one header set & for odd row I put another header set).
    in this case how a customized header can help me ?
    And I could not see any function for setting data (if I customize QHeaderView) rather than QHeaderView::setRootIndex(QModelIndex);

    Thanks.

    The header takes its data from headerData() method of the model. Simply provide a custom model for it. It can even be empty just make it return whatever you need from headerData().
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
