pygubu-tcpclient-example

This is an example application based on the python module pygubu.

Tcpclientk is two things: a TCP client and a GUI based on python3, pygubu and Tkinter.

Previously, writing portable simple GUIs was a difficult task, now thanks to pygubu, almost everybody can do it.

Anyway, pygubu deserves more example code, this is why I've started to write this example.

Packaging this example for Windows with pyinstaller

This procedure was tested on Windows 7 and Python 3.6.1, it is still experimental but it works:

1. In Windows, install python3

2. Open a command shell and type:

   pip install pygubu

3. Then, type:

   pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip

4. In the pygubu-tcpclient-example directory, type:

   pyi-makespec --onefile

   This will produce a file called onefile.spec

5. Edit the .spec file to add some more data tuples, like this:

   datas=[('tcpclientk.png', '.'), ('tcpclientk.ui','.'), ('tcpclientk_about_dialog.ui', '.')],

   These files will be automatically copied to the bundle directory. There is some code in tcpclientk to detect if it is run from a bundle and adapt the PATH accordingly, see NOTES below

6. Run pyinsaller onefile.spec, this will produce one single .exefile under the dist directory. This file contains all dependencies that are needed to run the example

NOTES:

• I needed to install a development version of pyinstaller, because I have had problems with the latest release. But maybe you don't need to do that anymore since these changes have been added to the latest release?

• Add from pygubu.builder import ttkstdwidgets to your source to avoid the error: ModuleNotFoundError: No module named 'pygubu.builder.ttkstdwidgets'

• To detect if the code runs in a bundle or not:

import sys
FILE_PATH = None  # To be set in __main__

if getattr( sys, 'frozen', False ) :
    # running in a bundle
    bundle_dir = sys._MEIPASS
else :
    # running live in a normal Pyton environment
    bundle_dir = os.path.dirname(os.path.abspath(__file__))

FILE_PATH = bundle_dir

# Then refer to all files from datas like this from your code:
os.path.join(FILE_PATH, "tcpclientk.ui"), etc...
