[Solved] How to add menu item and trigger action?

[webphone]

I would like to build a menu bar for a GUI desktop application in QT.

In the designer, how can I add menu bar and menu item and how to trigger the action of the menu item?

Is there any walkthrough tutorial?

to set up your environment using qt Creator just follow this wizard :
QT Creator Manual > Creating a Qt C++ Application

but choose for QMainWindow instead of QWidget

Menu items have added, how can I trigger the code?

Right mouse button in action editor...
then "go to slot"
and choose the signal you want.
