- All slots/property of QObject are automatically exposed to the python interpreter
- Concept of decorator
- Expose regular cpp method of QObject
- Expose object and method of pure cpp classes
- Complete wrapping of all Qt Classes
- From PythonQt website: In contrast to PyQt , PythonQt is not a complete Python wrapper around the complete Qt functionality. So if you are looking for a way to write complete applications in Python using the Qt GUI, you should use PyQt.
- See http://pythonqt.sourceforge.net/
Implementation
CTK Layer
- qCTKConsoleWidget
- qCTKShellPython
- qCTKAbstractPythonManager:
- registerPythonQtDecorator, registerClassForPythonQt, registerCPPClassForPythonQt, executeString, getVariable, executeFile, ...
- also virtual methods: pythonPaths and preInitialization
Concrete example
- Slicer superbuild download and patch SVN PythonQt head
- Slicer CMake script pre-compile all slicer .py class
- VTK all wrapped in python and exposed
- qSlicerPythonManager
void qSlicerPythonManager::preInitialization() { Superclass::preInitialization(); // Register decorators this->registerPythonQtDecorator(new qSlicerBaseQTBasePythonQtDecorators(this)); qSlicerCoreApplication* app = qSlicerCoreApplication::application(); // Add object to python interpreter context this->addObjectToPythonMain("_qSlicerCoreApplicationInstance", app); // Evaluate application script this->executeFile(app->slicerHome() + "/bin/Python/slicer/slicerqt.py"); }
- logic.py
