I was thinking of Separating functions from GUI. I want when have different classes of GUIs that share functions, then I will have one class full of function/methods on need. However I failed to separate them, for I could not make instance of Functions class in the gui class in order to utilize its methods. Below is my trial with one function (Pause) shifted to another class. The original code was written by Paulthom12345, So I hope he will not worry for me to use his codes here with some fiddling lol:

It crashes: NameError: name 'Events' is not defined

import wx
import wx.media
import os

class MainFrame(wx.Frame):
    self.functions = Events()
    def __init__(self):

        self.load.Bind(wx.EVT_BUTTON,self.loadFile)

        self.play = wx.Button(self.panel,wx.ID_ANY,"Play")

        self.slider = wx.Slider(self.panel,wx.ID_ANY,size = (300,-1))
        self.slider.Bind(wx.EVT_SLIDER,self.Seek)

        self.panel.SetSizer(sizer)

        self.Show()
       
        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER, self.onTimer)
        self.timer.Start(100)
       
        self.panel.SetInitialSize()
        self.SetInitialSize()

    def onTimer(self,event):

        self.info_pos.SetLabel("Pos: %i seconds" % (int(current)/1000))
        self.slider.SetValue(current)

        msg = wx.FileDialog(self, message = "Open a media file",
                               style = wx.OPEN,
                               wildcard = "Media Files|*.wma;*.mp3;*.avi")

            else:

class Events():   
    def __init__(self):
        def pauseFile(self,event):
            self.Pause()

This worked for me:

import wx

        self.player = player
    
    def pauseFile(self,event):

        self.panel = wx.Panel(self)
        self.player = wx.media.MediaCtrl(self.panel)
        self.functions = Events(self.player)
        self.load = wx.Button(self.panel,wx.ID_ANY,"Load File")
        self.load.Bind(wx.EVT_BUTTON,self.loadFile)

        self.play = wx.Button(self.panel,wx.ID_ANY,"Play")
        self.play.Bind(wx.EVT_LEFT_DOWN,self.playFile)

        self.pause = wx.Button(self.panel,wx.ID_ANY,"Pause")
        self.pause.Bind(wx.EVT_LEFT_DOWN,self.functions.pauseFile)

        self.stop = wx.Button(self.panel,wx.ID_ANY,"Stop")
        self.stop.Bind(wx.EVT_LEFT_DOWN,self.stopFile)

        self.slider = wx.Slider(self.panel,wx.ID_ANY,size = (300,-1))
        self.slider.Bind(wx.EVT_SLIDER,self.Seek)

        self.info_name = wx.StaticText(self.panel,wx.ID_ANY,"Name:")
        self.info_length = wx.StaticText(self.panel,wx.ID_ANY,"Time:")
        self.info_pos = wx.StaticText(self.panel,wx.ID_ANY,"Pos:")
       
        sizer = wx.GridBagSizer(5,5)
        sizer.Add(self.slider,(1,1),(1,4))

        sizer.Add(self.info_pos,(4,1),(1,4))
        self.panel.SetSizer(sizer)

        self.Show()
       
        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER, self.onTimer)
        self.timer.Start(100)
       
        self.panel.SetInitialSize()
        self.SetInitialSize()

    def onTimer(self,event):
        current = self.player.Tell()

        self.slider.SetValue(current)
      
    def Seek(self,event):
      
        self.player.Seek(self.slider.GetValue())
     
       
    def loadFile(self,event):
       
        msg = wx.FileDialog(self, message = "Open a media file",

        if msg.ShowModal() == wx.ID_OK:
            path = msg.GetPath()
            self.path = path
           
            if not self.player.Load(path):
                wx.MessageBox("Unable to load this file, it is in the wrong format")
            else:
                self.player.Play()
               
               
               
               
    def playFile(self,event):

        self.player.Stop()
   
       
app = wx.App(False)

app.MainLoop()

Oh and there is a little bug i forgot about in the code. Just you have to remember at some point to add self.player to the sizer otherwise videos dont play.
