Using Custom Images while Packaging

Note: if you're new to packaging Gooey, checkout the main Packaging Guide first!

Gooey comes with a set of six default icons. These can be overridden with your own custom images/icons by telling Gooey to search additional directories when initializing. This is done via the image_dir argument to the Gooey decorator.

@Gooey(program_name='Custom icon demo', image_dir='/path/to/images')
def main():
    # rest of program

While this works for regular executions, a little additional work is required to make sure that your images will actually be available when running as a stand alone executable.

To make your custom images available after packaging, you have to do two things.

Step 1: wrap the path to your image directory in the local_resource_path() function provided by Gooey. When PyInstaller runs your application, it decompresses all the contents to a random temp directory. This function will handle the logic of resolving that directory and fetching your resources from it.

from gooey import Gooey, local_resource_path

@Gooey(image_dir=local_resource_path('relative/path/to/images'))
def main():
   ...

Step 2: Update build.spec to include the image directory during bundling. This is done by giving the path to your Images as a Tree object to Pyinstaller's EXE section.

# -*- mode: python ; coding: utf-8 -*-

import os
...
# LOOK AT ME! I AM A TREE OBJECT 
image_overrides = Tree('path/to/images', prefix='path/to/images')

...

exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          options,
          image_overrides,  # <-- NEW 
          name='APPNAME',
          debug=False,
          strip=None,
          upx=True,
          console=False,
          icon=os.path.join(gooey_root, 'images', 'program_icon.ico'))

And then build via PyInstaller as usual.

pyinstaller -F --windowed build.spec

PyInstaller will now include your images in its bundle.
