how to put a image as a background in wxpython

Question

How to add background image to panel1? Which command is there?

Code:

import wx
import wx
appy=wx.App()

class cg(wx.Frame) :
     def __init__(self,parent,id) :
         wx.Frame.__init__(self,parent,id,'GPA',pos=(1000,600),size=(600,400))
         #splitter = wx.SplitterWindow(self, -1)
         panel1 = wx.Panel(self)
         panel2 = wx.Panel(panel1, -1,size=(600,200),style=wx.BORDER_SUNKEN)
         panel3 = wx.Panel(panel1, -1,pos=(0,200),size=(600,200),style=wx.BORDER_SUNKEN)
         #panel3=wx.panel(panel1,-1,pos=(300,200),size=(600,200),style=wx.BORDER_SUNKEN)
         #panel13 = wx.Panel(panel1, -1, style=wx.BORDER_SUNKEN)
         #panel13 = wx.Panel(panel1, -1, style=wx.BORDER_SUNKEN)
         #panel13 = wx.Panel(panel1, -1, style=wx.BORDER_SUNKEN)

         #button1=wx.Button(panel1,label='exit',pos=(10,10),size=(10,10))
         #self.cnt1=wx.TextCtrl(panel1,pos=(40,60),size=(120,30))

if __name__=='__main__' :

     app=wx.PySimpleApp()
     frame=cg(parent=None,id=-1)
     frame.Show()
     app.MainLoop()

The corrected example from The Mouse vs. The Python.

import wx

        self.frame = parent
 
        sizer = wx.BoxSizer(wx.VERTICAL)

Setting self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM) no longer works. That line should be removed or use self.SetBackgroundStyle(wx.BG_STYLE_ERASE) but given that that is the default, best just leave it out.

Steve Barnes Over a year ago

@RolfofSaxony: Thanks for bringing this up. Actually, since we are defining an EVT_ERASE_BACKGROUND handler this is now recommended to be BG_STYLE_PAINT, see docs.wxpython.org/…

Vaidøtas I. Over a year ago

@SteveBarnes then why does BG_STYLE_PAINT not work and BG_STYLE_ERASE does?

Steve Barnes Over a year ago

@VaidøtasI. I don't know I am just going on the documented behaviour.

A simple search would have brought you to this answer from The Mouse vs. The Python.

# create a background image on a wxPython panel
# and show a button on top of the image

import wx

class Panel1(wx.Panel):
    """class Panel1 creates a panel with an image on it, inherits wx.Panel"""
    def __init__(self, parent, id):
        # create the panel
        wx.Panel.__init__(self, parent, id)
        try:
            # pick an image file you have in the working folder
            # you can load .jpg  .png  .bmp  or .gif files
            image_file = 'roses.jpg'
            bmp1 = wx.Image(image_file, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
            # image's upper left corner anchors at panel coordinates (0, 0)
            self.bitmap1 = wx.StaticBitmap(self, -1, bmp1, (0, 0))
            # show some image details
            str1 = "%s  %dx%d" % (image_file, bmp1.GetWidth(), bmp1.GetHeight()) 
            parent.SetTitle(str1)
        except IOError:
            print "Image file %s not found" % imageFile
            raise SystemExit

        # button goes on the image --> self.bitmap1 is the parent
        self.button1 = wx.Button(self.bitmap1, id=-1, label='Button1', pos=(8, 8))

app = wx.PySimpleApp()
# create a window/frame, no parent, -1 is default ID
# change the size of the frame to fit the backgound images
frame1 = wx.Frame(None, -1, "An image on a panel", size=(350, 400))
# create the class instance
panel1 = Panel1(frame1, -1)
frame1.Show(True)
app.MainLoop()

can u please tell how to load the jpg image?

pedram Over a year ago

Have you read the code or visited the site? It is explained very clearly: image_file = 'roses.jpg'. It looks in the same file as the script is run. If you want to provide a full path, look into os.path.join. Would appreciate you selecting this as best-answer too if it helps.
