wxPython - Image on button in Python

In this particular article we will learn how can we add image to a button in GUI using wxPython. This can be achieved using BitmapButton() constructor of wx.BitmapButton class in wx. Following Window Styles are supported :

• wx.BU_LEFT: Left-justifies the bitmap label.
• wx.BU_TOP: Aligns the bitmap label to the top of the button.
• wx.BU_RIGHT: Right-justifies the bitmap label.
• wx.BU_BOTTOM: Aligns the bitmap label to the bottom of the button.

Syntax :

wx.StaticText(self, parent, id=ID_ANY, bitmap=NullBitmap, 
              pos=DefaultPosition, size=DefaultSize, style=0, 
           validator= DefaultValidator, name=StaticTextNameStr)

Parameters :

Parameter	Input Type	Description
parent	wx.Window	Parent window. Should not be None.
id	wx.WindowID	Control identifier. A value of -1 denotes a default value.
bitmap	wx.Bitmap	Bit to be displayed.
pos	wx.Point	Window position.
size	wx.Window	Window size.
style	long	Window style.
validator	wx.Validator	Window validator.
name	string	Window name.

Example Code: 

# import wxPython
import wx

# event function for button
def onButton(event):
    print("Button pressed.")

app = wx.App()
frame = wx.Frame(None, -1, 'win.py')
frame.SetDimensions(0, 0, 200, 70)
panel = wx.Panel(frame, wx.ID_ANY)

# open image from disk
bmp = wx.Bitmap("/home/rahul101/Desktop/wxPython/images.png", wx.BITMAP_TYPE_ANY)
# create image button using BitMapButton constructor
button = wx.BitmapButton(panel, id = wx.ID_ANY, bitmap = bmp,
                          size =(bmp.GetWidth()+10, bmp.GetHeight()+10))
 
button.Bind(wx.EVT_BUTTON, onButton)
button.SetPosition((10, 10))

frame.Show()
frame.Centre()
app.MainLoop()

Output :
