是否可以在wxPython中更改滑块的厚度？

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="Slider Example")
        
        panel = wx.Panel(self)
        
        slider = wx.Slider(panel, value=50, minValue=0, maxValue=100, style=wx.SL_HORIZONTAL)
        slider.SetPageSize(20)  # 设置滑块的页面大小为20
        
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(slider, 0, wx.EXPAND|wx.ALL, 20)
        panel.SetSizer(sizer)
        
if __name__ == "__main__":
    app = wx.App()
    frame = MyFrame()
    frame.Show()
    app.MainLoop()
