Using the tkinter Python Module

The tkinter Python standard library module/package provides a Python interface to tcl/tk/tkinter. This interface allows you to create GUI applications.

PyOxidizer has partial support for using tkinter. Since tkinter isn’t a commonly used Python feature, you must opt in to enabling it.

Installing tcl Files

tkinter requires both a Python extension module compiled against tcl/tk and tcl support files to be loaded at run-time.

All the built-in Python distributions shipping with PyOxidizer provide tkinter support with the exception of the Windows standalone_static distributions.

However, the tcl support files aren’t installed by default.

To install tcl support files, you will need to set the tcl_files_path attribute of a PythonExecutable instance to the directory you want to install these files into. e.g.

def make_exe(dist):
    exe = dist.to_python_executable(name="myapp")
    exe.tcl_files_path = "lib"

    return exe

When tcl_files_path is set to a non-None value, the tcl files required by tkinter are installed in that directory and the built executable will automatically set the TCL_LIBRARY environment variable at run-time so the tcl interpreter uses those files.

tcl Files Prevent Self-Contained Executables

The tcl interpreter needs to load various files off the filesystem at run-time. PyOxidizer does not (yet) support embedding these files in the binary and loading them from memory or extracting them at run-time.

So if you need to use tkinter, you cannot have a single-file executable that works without a dependency on tcl files elsewhere on the filesystem.
