QHeaderView change mouse click behavior

[Qutie]

Hi everyone

I have a table view with a QSortFilterProxyModel. The user can bind a column to QSortFilterProxyModel by Ctrl+Click the header. The column bound to the proxy model gets marked with an asterisks, but also the the sort behavior gets changed. How can I prevent the latter if the user "Ctrl+Clicks". The sort behavior should only be changed while no Ctrl-key is pressed.

Do I have to subclass QHeaderview and reimplement mouse events?

yes, exactly.
Reimplement mousepress/mouserelease event handlers (alternatively install an event-filter) and simply don't call the base-class implementation in case CTRL is contained in the event.

Thank's. After set my subclassed header view to TableView, the signal SectionPressed() was not fired. QTableView sets standard HeaderView SectionClickable to true. So I had to set it as well to true.

MarkHeaderView::MarkHeaderView(Qt::Orientation orientation, QWidget *parent)
   :QHeaderView(orientation,parent)
{
   setSectionsClickable(true);
   setHighlightSections(true);
}

void MarkHeaderView::mousePressEvent(QMouseEvent *e){
  if(QGuiApplication::queryKeyboardModifiers() != Qt::ControlModifier){
      QHeaderView::mousePressEvent(e);
   }
  else{
      emit SectionCtrlPressed(logicalIndexAt(e->pos()));
  }
}
