I'm trying to make a slider, but for some reason all the numbers of the slider get in left corner of the frame, all at the same position(instead of the 1;left,the position of the slider;middle and 100; right). Hope you can imagine what I mean, unfortunately I can't place a screenshot (or can I?)

Here is my code:
Code:
import wx

class freem(wx.Frame):

    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,size=(300,100))
        panel=wx.Panel(self)


        slider=wx.Slider(panel,-1,50,1,100,pos=(10,10),size=(250,-1),style=wx.SL_AUTOTICKS | wx.SL_LABELS)
        slider.SetTickFreq(500,200)
        
if __name__=='__main__':
    app=wx.PySimpleApp()
    frame=freem(parent=None,id=-1)
    frame.Show()
    app.MainLoop()
Using wx I also get the next message/warning:
Code:
Warning (from warnings module):
  File "/Users/wybevanderwielen/Python/wx10.py", line 14
    app=wx.PySimpleApp()
wxPyDeprecationWarning: Using deprecated class PySimpleApp.
Im using Phyton 2.7.3 on a Mac OS X 10.6.8

Hope someone can help!
