currently i'm working on a GUI that analyzes a PCAP file. I'm a total beginner in Python/wxPython so I would really appreciate some friendly help!

I'm using tshark to read my PCAP file and wxPython4.0.1 for the GUI. The output of the tshark read is stored in a subprocess.popen(). From here on, I intend to show the output through a ListCtrl in the GUI so that it is more organized and readable. Is there a way to add the tshark output into the ListCtrl?

Here's the main part of my code:

import wx

import os

from subprocess import Popen, PIPE

import sys



class MyFrame(wx.Frame):

    def __init__(self, *args, **kwds):

        # begin wxGlade: MyFrame.__init__

        kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE

        wx.Frame.__init__(self, *args, **kwds)

        self.SetSize((965, 600))

        self.panel_1 = wx.Panel(self, wx.ID_ANY)

        self.list_ctrl_1 = wx.ListCtrl(self.panel_1, wx.ID_ANY, style=wx.LC_HRULES | wx.LC_REPORT | wx.LC_SINGLE_SEL | wx.LC_VRULES)



        # Menu Bar

        self.frame_menubar = wx.MenuBar()

        wxglade_tmp_menu = wx.Menu()

        item = wxglade_tmp_menu.Append(wx.ID_ANY, "Upload PCAP", "")

        self.Bind(wx.EVT_MENU, self.on_menu_upload, id=item.GetId())

        self.frame_menubar.Append(wxglade_tmp_menu, "File")

        self.SetMenuBar(self.frame_menubar)

        # Menu Bar end



        self.__set_properties()

        self.__do_layout()



        # end wxGlade



    def __set_properties(self):

        # begin wxGlade: MyFrame.__set_properties

        self.SetTitle("Analysis")

        self.list_ctrl_1.AppendColumn("Time", format=wx.LIST_FORMAT_LEFT, width=193)

        self.list_ctrl_1.AppendColumn("#", format=wx.LIST_FORMAT_LEFT, width=185)

        self.list_ctrl_1.AppendColumn("Source", format=wx.LIST_FORMAT_LEFT, width=193)

        self.list_ctrl_1.AppendColumn("Destination", format=wx.LIST_FORMAT_LEFT, width=193)

        self.list_ctrl_1.AppendColumn("Protocol", format=wx.LIST_FORMAT_LEFT, width=193)

        # end wxGlade



    def __do_layout(self):

        # begin wxGlade: MyFrame.__do_layout

        sizer_1 = wx.BoxSizer(wx.VERTICAL)

        sizer_2 = wx.BoxSizer(wx.VERTICAL)

        sizer_2.Add(self.list_ctrl_1, 1, wx.EXPAND, 0)

        sizer_2.Add((0, 0), 0, 0, 0)

        self.panel_1.SetSizer(sizer_2)

        sizer_1.Add(self.panel_1, 1, wx.EXPAND, 0)

        self.SetSizer(sizer_1)

        self.Layout()

        # end wxGlade



    def on_menu_upload(self, event):  # wxGlade: MyFrame.<event_handler>

            openFileDialog = wx.FileDialog(self, "Open", "", "","*.pcap",     #creates a filedialog that only allow user to select .pcap files 

                                        wx.FD_OPEN | wx.FD_FILE_MUST_EXIST)



            if openFileDialog.ShowModal() == wx.ID_OK:

                  evidencePath = openFileDialog.GetPath()                         #get path of selected dd file

                  filename = os.path.basename(evidencePath)

                  cmd = ['tshark', '-r', filename]

                  process = Popen(cmd, stdout=PIPE, stderr=PIPE)

                  stdout, stderr = process.communicate()

                  """self.list_ctrl_1.InsertStringItem(stdout)"""  #insert the output into the ListCtrl



                  print("PCAP Uploaded")



            else: 

                  print("Error Occurred!")



# end of class MyFrame
