===== Kezdés =====

<code python MainFrame.py>
import wx

class MainFrame(wx.Frame):
    pass

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()
</code>



===== Konstruktor létrehozása =====


<code python MainFrame.py>
import wx

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


class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()
</code>


===== Két vezérlő elhelyezése =====


<code python MainFrame.py>
import wx

class MainFrame(wx.Frame):
    def __init__(self, parent):
        super(MainFrame, self).__init__(parent)
        self.button1 = wx.Button(self, label='Mehet')
        self.button1.SetPosition((50, 50))
        self.entry = wx.TextCtrl(self)
        self.entry.SetPosition((50, 100))

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()

===== Eseménykezelés =====

<code python MainFrame.py>
import wx

class MainFrame(wx.Frame):
    def __init__(self, parent):
        super(MainFrame, self).__init__(parent)
        self.button1 = wx.Button(self, label='Mehet')
        self.button1.SetPosition((50, 50))
        self.Bind(wx.EVT_BUTTON, self.onClickGomb1, self.button1)
        self.entry = wx.TextCtrl(self)
        self.entry.SetPosition((50, 100))
    def onClickGomb1(self, event):
        print('Működik')

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()

===== Az esemény fejlesztése =====

<code python MainFrame.py>

import wx

class MainFrame(wx.Frame):
    def __init__(self, parent):
        super(MainFrame, self).__init__(parent)
        self.button1 = wx.Button(self, label='vmi')
        self.button1.SetPosition((50, 50))
        self.Bind(wx.EVT_BUTTON, self.onClickGomb1, self.button1)
        self.entry = wx.TextCtrl(self)
        self.entry.SetPosition((50, 100))
    def onClickGomb1(self, event):
        numStr = self.entry.GetValue()
        product = int(numStr) * 2
        self.entry.SetValue(str(product))

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()

===== InitUI létrehozása =====

<code python MainFrame.py>

import wx

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

    def InitUI(self):
        self.button1 = wx.Button(self, label='vmi')
        self.button1.SetPosition((50, 50))
        self.Bind(wx.EVT_BUTTON, self.onClickGomb1, self.button1)
        self.entry = wx.TextCtrl(self)
        self.entry.SetPosition((50, 100))
        
    def onClickGomb1(self, event):
        numStr = self.entry.GetValue()
        product = int(numStr) * 2
        self.entry.SetValue(str(product))

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()

===== Méretező használata =====

<code python MainFrame.py>

import wx

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

    def InitUI(self):
        self.button1 = wx.Button(self, label='vmi')
        self.Bind(wx.EVT_BUTTON, self.onClickGomb1, self.button1)
        self.entry = wx.TextCtrl(self)

    def InitLayout(self):
        self.sizer1 = wx.BoxSizer(wx.VERTICAL)
        self.sizer1.Add(self.button1)
        self.sizer1.Add(self.entry)
        self.SetSizer(self.sizer1)

    def onClickGomb1(self, event):
        numStr = self.entry.GetValue()
        product = int(numStr) * 2
        self.entry.SetValue(str(product))

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()
        return True

app = App()
app.MainLoop()

===== Szétválasztás =====

<code python App.py>
import wx

from views.MainFrame import MainFrame
from controllers.Controller import Controller

class App(wx.App):
    def OnInit(self):
        frame = MainFrame(None)
        frame.Show()

        self.sizer1.Add(self.button1)
        self.sizer1.Add(self.entry)
        self.SetSizer(self.sizer1)

<code python controllers/Controller.py>
import wx
from views.MainFrame import MainFrame

class Controller:
    def __init__(self, mainFrame: MainFrame):
        self.mainFrame = mainFrame
        self.mainFrame.Bind(wx.EVT_BUTTON, self.onClickGomb1, self.mainFrame.button1)

    def onClickGomb1(self, event):
        numStr = self.mainFrame.entry.GetValue()
        product = int(numStr) * 2
