wx.html telepítés:
  apt install libwebkit2gtk-4.0-dev


wx.html2 telepítés:
  apt install python3-wxgtk-webview4.0


===== Egyszerű böngésző =====

<code python MainFrame.py>

import wx
import wx.html2

class MainFrame(wx.Frame):
    def __init__(self, parent):
        super(MainFrame, self).__init__(parent)
        self.InitUI()
        self.InitLayout()

    def InitUI(self):
        self.SetSize((800,600))
        self.address = wx.TextCtrl(self)
        self.goButton = wx.Button(self, label='Go')
        self.goButton.Bind(wx.EVT_BUTTON, self.onClickGoButton)
        self.browser = wx.html2.WebView.New(self)
        self.browser.Bind(wx.html2.EVT_WEBVIEW_NAVIGATING, self.onWebViewNavigating)
        self.browser.

        self.toolBar = self.CreateToolBar(wx.TB_HORIZONTAL, wx.ID_ANY)
        self.backTool = self.toolBar.AddTool(1001, 'Vissza', wx.Bitmap('back.png'))
        self.Bind(wx.EVT_TOOL, self.onClickBackTool, self.backTool)

        self.toolBar.Realize()

    def InitLayout(self):
        rootBox = wx.BoxSizer(wx.VERTICAL)
        headBox = wx.BoxSizer(wx.HORIZONTAL)
        workBox = wx.BoxSizer(wx.HORIZONTAL)

        rootBox.Add(headBox, 0, wx.EXPAND)
        rootBox.Add(workBox, 1, wx.EXPAND)

        headBox.Add(self.address, 1)
        headBox.Add(self.goButton, 0)

        workBox.Add(self.browser, -1, wx.EXPAND | wx.ALL, 5)

        self.SetSizer(rootBox)

    def onClickGoButton(self, event):
        self.browser.LoadURL(self.address.GetValue())

    def onWebViewNavigating(self, event):
        url = event.GetURL()
        print(url)
    def onClickBackTool(self, event):
