I'm building a Windows one file executable of my wxPython app with Pyinstaller. I want to add a window icon and doing pyinstaller --icon=test.ico --onefile --noconsole test.pyw is perfectly fine only if I put the test.ico file just next to the builded executable. This makes me distribute both the exe and the icon, and that's at least uncomfortable.

I also do

icon = wx.EmptyIcon()
icon.CopyFromBitmap(wx.Bitmap("test.ico", wx.BITMAP_TYPE_ANY))
self.SetIcon(icon)

in my wxPython app.

My research says a suggestion to hardcode a base64 string representation of the icon but it's an insanely long string as I also need to print on paper my code. I saw this other post and I sense it has my answer but I just don't understand it.

So. How can I embed the icon to the exe?

EDIT: .spec file

# -*- mode: python -*-

block_cipher = None

a = Analysis(['test.pyw'],
         pathex=['D:\\test'],
         binaries=[],
         datas=[],
         hiddenimports=[],
         hookspath=[],
         runtime_hooks=[],
         excludes=[],
         win_no_prefer_redirects=False,
         win_private_assemblies=False,
         cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
         cipher=block_cipher)
exe = EXE(pyz,
      a.scripts,
      a.binaries,
      a.zipfiles,
      a.datas,
      name='test',
      debug=False,
      strip=False,
      upx=True,
      console=False , icon='test.ico')

First, with --icon option you already have included the .ico into your executable. But wxPython has no way to extract it from the .exe (I suppose it would not be all that hard by using windows system calls, but that is not the point).

Therefore you have to include the .ico-file a second time, this time into the file system.

The stackoverflow article linked by you already has the answers:

  1. Modify the .spec file to include the icon file into the bundled application.

  2. When running the application, it will decompress the bundled files in a temporary location. As pointed out in the article referenced by you, the resource path is specified in sys._MEIPASS. Do not forget to consider subdirectories (e. g. a images for ./images/icon.ico) when forming the full file qualifier.

Show your .spec file modification and the code retrieving the icon to get further help

  • Edited as requested. So you say I just need to add that code in to my app? But where and how? – Javier Dec 12 '16 at 18:12
  • On ``CopyFromBitmap``, replace ``"test.ico"`` with the result from the call to ``resource_path`` as described in the other stackoverplow post. And in your spec file you have still add the ``test.ico`` to ``a.datas`` (remember, ``icon=`` adds the icon to the binary). – nepix32 Dec 13 '16 at 07:07
  • Perfect. Just for the record, it is needed to add the function in that article to the wxPython script. I did not as a class' method but outside it. Working fine. – Javier Dec 13 '16 at 14:34
