Question

I’m not having any luck at setting the horizontal position of wxPythons slider controls. In all my tests setting the horizontal position has no effect on the placement of the control.
Can any one tell me what I’m missing?
Thanks

Here’s what I’ve tried:

    import wx 

    class SliderFrame(wx.Frame):
        def __init__(self):
            wx.Frame.__init__(self, None, -1, 'Slider Example', size=(400, 600))
            panel = wx.Panel(self, -1)
            self.count = 0
            hslider1 = wx.Slider(panel, 100, 25, 1, 100, pos=(10, 10),
                    size=(250, -1),
                    style=wx.SL_HORIZONTAL | wx.SL_AUTOTICKS | wx.SL_LABELS )
            hslider1.SetTickFreq(5, 1)

            hslider2 = wx.Slider(panel, 100, 25, 1, 100, pos=(100, 330),
                    size=(250, -1),
                    style=wx.SL_HORIZONTAL | wx.SL_AUTOTICKS | wx.SL_LABELS )
            hslider2.SetTickFreq(5, 1)


            vslider1 = wx.Slider(panel, 100, 25, 1, 100, pos=(15, 70),
                    size=(-1, 250),
                    style=wx.SL_VERTICAL | wx.SL_AUTOTICKS | wx.SL_LABELS )
            vslider1.SetTickFreq(20, 1)



    app = wx.PySimpleApp()
    frame = SliderFrame()
    frame.Show()
    app.MainLoop()

That’s odd. An obvious work around is to put the slider in a panel that you can position (below), or use sizers. Also, note that the error goes away if you use

    p2 = wx.Panel(panel, -1, size=(250, 100), pos=(100,330))
    hslider2 = wx.Slider(p2, -1, 27, 0, 100,
            size=(250, -1),
            style=wx.SL_HORIZONTAL | wx.SL_AUTOTICKS | wx.SL_LABELS )
    hslider2.SetTickFreq(5, 1)

It also works to use SetDimensions, like this:

    hslider2 = wx.Slider(panel, -1, 27, 0, 100,
            style=wx.SL_HORIZONTAL | wx.SL_AUTOTICKS | wx.SL_LABELS )
    hslider2.SetTickFreq(5, 1)
    hslider2.SetDimensions(100, 330, 250, -1)
