Right click over QHeader?
Message 1 in thread
Hello,
I need to setup an action over right click on a vertical qheader of a qtable. Can somebody give me an idea on the easiest way to achieve this?
Thanks in advance.

QHeaderView *headerView = header();
connect(headerView, SIGNAL(sectionDoubleClicked ( int) ), this,
SLOT(setRowOrColumn(int)));
Then, do what you want in the slot: setRowOrColumn(int)

I am sorry I forgot to say that I need to this on Qt3, and here I don't have QHeaderView but QHeader and this class hasn't a signal for the right click as I can see on the documentation.
Thanks.

Overwrite contextMenuEvent() which is invoked by right click.

Hello,
You could install an event filter on the header and check for a right click.
It works well for me.
In a subclass of QTable:
verticalHeader()->installEventFilter( this );
And in eventFilter( QObject * obj, QEvent * e ):
QHeader * vertHeader = verticalHeader();
if ( obj == vertHeader ) {
if ( e && e->type() == QEvent::MouseButtonPress ) { // mouse press
event?
QMouseEvent *mEvent = (QMouseEvent*)e;
if ( mEvent && mEvent->button() == Qt::RightButton ) { // right
button?
DoHeaderContextMenuEvent( (QContextMenuEvent*)e);

Ok, but I need to do it on QHeader which I know how to do, but then I need QTable uses my new QHeader, how can I do that?
I am sorry if this question is too simple. Thanks

I am sorry I forgot to say that I need to this on Qt3, and here I don't have
