PythonQt

Examples

Examples are available in the examples directory. The PyScriptingConsole implements a simple interactive scripting console that shows how to script a simple application. The PyLauncher application can be used to run arbitrary PythonQt scripts given on the commandline.

The following shows a simple example on how to integrate PythonQt into your Qt application:

#include "PythonQt.h"

#include <QApplication>

...

int main(int argc, char *argv[])

{

QApplication qapp(argc, argv);

// init PythonQt and Python itself

PythonQt::init();

// get a smart pointer to the __main__ module of the Python interpreter

PythonQtObjectPtr context = PythonQt::self()->getMainModule();

// add a QObject as variable of name "example" to the namespace of the __main__ module

PyExampleObject example;

context.addObject("example", &example);

// do something

context.evalScript("print example");

context.evalScript("def multiply(a,b):\n return a*b;\n");

QVariantList args;

args << 42 << 47;

QVariant result = context.call("multiply", args);

...

PythonQt.h

PythonQtObjectPtr

a smart pointer that stores a PyObject pointer and that handles reference counting automatically

Definition PythonQtObjectPtr.h:57

PythonQtObjectPtr::evalScript

QVariant evalScript(const QString &script, int start=Py_file_input)

evaluates the given script code in the context of this object and returns the result value

PythonQtObjectPtr::addObject

void addObject(const QString &name, QObject *object)

add the given object to the module as a variable with name (it can be removed via clearVariable)

PythonQtObjectPtr::call

QVariant call(const QString &callable, const QVariantList &args=QVariantList(), const QVariantMap &kwargs=QVariantMap())

call the given python object (in the scope of the current object), returns the result converted to a ...

PythonQt::init

static void init(int flags=IgnoreSiteModule|RedirectStdOut, const QByteArray &pythonQtModuleName=QByteArray())

PythonQt::getMainModule

PythonQtObjectPtr getMainModule()

get the main module of python

PythonQt::self

static PythonQt * self()

get the singleton instance
