The wx.BitmapButton shows an image, great for those folks who think that a picture is worth a thousand words. The snippet gives an example how to load the image, size the button, and put the image on the the button.

# Example of a wxPython Frame, Panel and BitmapButton
# wx.BitmapButton(parent, id, bitmap, pos = wx.DefaultPosition, size = wx.DefaultSize, style=0)
# best to size the button to the image width and height plus a border margin
# tested with Python24 and wxPython26     vegaseat    22jun2006

import wx

class MyFrame(wx.Frame):
    """make a frame, inherits wx.Frame, add a panel and button"""
    def __init__(self):
        # create a frame, no parent, default to wxID_ANY
        wx.Frame.__init__(self, None, wx.ID_ANY, 'wxBitmapButton',
            pos=(300, 150), size=(300, 350))
        # panel needed to display button correctly
        self.panel1 = wx.Panel(self, -1)
        
        # pick a button image file you have (.bmp .jpg .gif or .png)
        imageFile = "Btn_down.jpg"
        image1 = wx.Image(imageFile, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
        self.button1 = wx.BitmapButton(self.panel1, id=-1, bitmap=image1,
            pos=(10, 20), size = (image1.GetWidth()+5, image1.GetHeight()+5))
        self.button1.Bind(wx.EVT_BUTTON, self.button1Click)
        
        # show the frame
        self.Show(True)

    def button1Click(self,event):
        self.SetTitle("Button1 clicked")  # test
        

application = wx.PySimpleApp()
# call class MyFrame
window = MyFrame()
# start the event loop
application.MainLoop()

Hi and thank you very much for posting your code. Helps a lot ! One question though : is there a way to update the image on the button once created and displayed ?
I'm writing a small application that display the weather. Every hour, I would like to update the information. I'm able to do it for text using ChangeValue on a TextCtrl but cannot find anything to update the 'weather image' that I have positionned on a BitmapButton. Any idea ?
Thank a lot.
