Right, kids are in bed. I should be studying for my java exam, but anyway.

QHeader inherits QWidget, which has a method, mousePressEvent(QEvent ev).
You can find out which kind of press occurred, and also the location of the 
press. From there, it's easy to instantiate and populate a QPopupMenu.

Keep in mind that signals/slots are meant for communication between objects. 
Events are meant for the handling of user input -- key presses, mouse stuff,
things like that.

Have you seen

and

where I discuss events?

In the end, it's very simple...

As for the rest: QGrid isn't a widget, but a layout manager, actually. For 
your purpose, QTable should work best. If you want in-place editing, then
QListView might work, too -- it can handle a lot of data, actually. But QTable 
was designed for large spreadsheet type applications -- the doc speaks of one 
million by one million cells, which should be ample. More, and your users 
might get lost.

 If you mean QGridView instead of QGrid -- that's a possibility, but it isn't 
easy to use that class. You will have to provide your own painting code, for 
instance.
