wxpython use wx.StaticBitmap, how to change image from event?

Hi,when I created a StaticBitmap, and a combobox. I had the idea that, as I would to change the image in StaticBitmap, from another event.
From combobox.

my code of StaticBitmap

self.m_bitmap1 = wx.StaticBitmap(self, wx.ID_LOGO, wx.Bitmap(u"example.png", wx.BITMAP_TYPE_ANY),
                                         wx.DefaultPosition, wx.DefaultSize, 0)
        self.m_bitmap1.SetBackgroundColour(wx.SystemSettings.GetColour(wx.SYS_COLOUR_ACTIVEBORDER))
        self.m_bitmap1.SetToolTip(u"logo of example")
        bSizer6.Add(self.m_bitmap1, 0, wx.ALIGN_CENTER | wx.ALL, 5)

Select allOpen in new window

event of combobox

def option_combo(self, event):
    selection = self.comboBox_Dir.GetSelection()
    if selection == 0:
        pass      # change image in StaticBitmap
 
 
    #print(selection)
    #event.Skip()
