QTreeWidget (qt4.3) and right click on items?
Message 1 in thread
I want to capture right click on items in QTreeWidget (to open a popup
menu). However, the signal does not send any information about button
used to do the click:
void QTreeWidget::itemClicked ( QTreeWidgetItem * item, int column ) [signal]
The clicked(...) slot in QAbstractItemView have no button distinction too.
I know I can subclass QTreeWidget and reimplement mousePressEvent,
but that may be a bit more cumbersome and not very elegant (one
"almost empty" class just to get right clicks).
IMHO that signal is pretty much useless if you don't know the button
that is used to click (left? right?).
Or did I miss something?
Also, as the popup menu may be also invoked by that key next to the
windows logo key, it may be nice to add some signal like
popupMenuInvoked(item, column) - i found nothing like that in docs
either

Take a look at QWidget::setContextMenuPolicy() and
QWidget::contextMenuEvent().
