qt4 - QT: Context menu (QMenu) reference from the QTableWidget -

-

I want to add a submenu in my context menu that is created like this: 

  Self.widget_alignment.setContextMenuPolicy (Qt.ActionsContextMenu)

where widget_alignment is QTableWidget .

I have created a new QMenu example: 

  exchange_bases_menu = QMenu (self.widget_alignment)

has added some actions , And I found a method

but I did not find any reference on the default reference menu for self.widget_alignment Additionally, this code: 

  self.widget_alignment.addMenu ( Exchange_bases_menu)

gave me: There is no attribute addMenu in the QTableWidget object.

How do I add my submenu to the default context menu?

According to the document, when setting a QWidget action context menu type , The widget will create a context menu based on the list of tasks assigned to the widget. To modify the list of tasks, you can call addAction , insertAction , or removeAction . So I hope you can do something like this (in C ++): 

  QAction * act_p = new queue ("submenu", widget_imainment); QWenu * Submenu_p = New QMenu (ACT_PP); // add item to submenu act_p-> Set menu (submenu_p); Widget_alignment-> Addiction (act_p);

Without trying it on my own, I hope that with the submenu created as a user, add "Has Submenu" option below the context menu generated for the widget. Will be shown.

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
