Truxton supports Python 3.8 via the Truxton.pyd library.

Overview

You must use the "import" directive to load this. Go to the C:\Program Files\Truxton\SDK folder and start Python.

import truxton

When you import truxton you will get all of the predefined constants for file type, data type, origins, locations, messages, entities, relations, events, media, objects, url methods, and urls. You can see them all by issuing a dir command.

>>> dir(truxton)

This will allow your Python code to use the same constant names as C, C++ and C# code.

>>> print(truxton.Type_JPEG)
203

Once you have this working, you can start playing with Truxton.

import truxton

def main():
  t = truxton.create()
  print(t.version)

if __name__ == "__main__":
  main()

You can create a folder for your project, copy the SDK contents into it and work from there.

Style

In general, when using a Truxton Python object, you will follow this pattern:

  1. Create the object
  2. Set the data members of the object
  3. Call save() to store the object in the Truxton database.

Until you call save(), nothing will appear in Truxton.

Classes

Truxton exposes several classes to Python.

Remarks

The Python API is designed primarily for programs to contribute to Truxton.

Truxton.pyd was developed using the C API with a thin adapter layer of code to translate from Python provider semantics to Truxton calls.
