button question

hi, i want to create a button that when pressed it will display a context menu...

You can use QContextMenuEvent.

Yes - QPushButton :)
Connect the clicked() signal to a slot, in that slot emit a QContextMenuEvent.

How about using QToolButton? It supports a menu with three different popup styles, out of the box.

I gave you the 'guide', what more do you need?
1. create a slot
2. connect the clicked() signal to that slot
3. in the slot emit the event

in the book c++ gui programming with qt4 i found another way{create an action, populate a menu, connect the menu with button}

Code:

---

oneAction= new QAction("do something!!", this);
connect(oneAction, SIGNAL(triggered()), this, SLOT(action()));
processMenu->addAction(oneAction);
menuButton->setMenu(&processMenu);

what is the difference? between these 2 ways?

That's exactly the same what Jpn suggested.

The method from the book that Jpn suggested uses QActions and signals.
I find it also better, so use it.
The other method is using an event, which probably is what happens with the signal method behind the scenes.
