Using C++Builder with Python
Natural to use C/C++ and Python
●
Lots of Python re-usable packages
●
C++ component architecture, GUI, language
●
Both are among the top used languages
●
Ways to use C++Builder and Python
●
–
–
–
Use the Delphi4Python components
Create Python C/C++ modules
Boost Library for Python
3
Delphi4Python Overview
●
Access to the Python APIs
●
Bi-directional interaction with both languages
●
Access to Python objects
●
Wrap C++ objects for use from Python
●
Create Python extension modules
4
Delphi4Python components
PythonEngine: Load and Connect. Low-level API access.
●
PythonModule: Create C++ module to be used by Python
●
PythonType: Python class to be used by C++Builder
●
PythonInputOutput: send/receive to/from Python script
●
PythonGUIInputOutput: connect Python output to a TMemo
●
PyDelphiWrapper: classes/objects accessible from Python
●
unit VarPython: provides hi-level access to Python Objects
●
5
Preparing C++Builder and Python4Delphi
Install Python distro - python.org - Win32 and Win64
●
PIP install Python modules required by C++ projects
●
Clone/Download Delphi4Python GitHub repository
●
Set IDE Library and browse paths for Win32 and Win64
●
Build and Install the components for 10.4+ or 10.3●
–
–
Set the Project | Options | Building | Delphi Compiler | Output - C++ |
C/C++ Output file Generation: Generate all C++Builder files (including
package libs)
Use command line Delphi compilers or RAD Studio IDE to generate files
that C++Builder needs
6
C++ Demos
●
Demo01 (from the Delphi4Python distro)
Execute Python scripts
– Display the results
Demo19 (from the Delphi4Python distro)
–
●
–
–
Define a new Module
Call C++ method from Python
7
Summary
●
●
●
C++Builder has multiple ways to
integrate with Python
Delphi4Python is the fastest/easiest
way to connect C++Builder with Python
Enjoy the benefits of leveraging the
active Python open-source community
