Public Member Functions inherited from ScriptingEnv
const QString	fileFilter () const
	Construct a filter expression from fileExtension(), suitable for QFileDialog.
bool	initialized () const
	initialization of the interpreter may fail; or there could be other errors setting up the environment
	ScriptingEnv (ApplicationWindow parent, const char langName)
virtual QString	stackTraceString ()
	If an exception / error occured, return a nicely formated stack backtrace.

Additional Inherited Members
Public Slots inherited from ScriptingEnv
virtual void	clear ()
	Clear the global environment. What exactly happens depends on the implementation.
void	decref ()
	Decrease the reference count. This should only be called by scripted and Script to avoid segfaults.
void	incref ()
	Increase the reference count. This should only be called by scripted and Script to avoid memory leaks.
virtual bool	setDouble (double, const char *)
virtual bool	setInt (int, const char *)
virtual void	startExecution ()
	If the implementation supports asynchronuos execution, activate it.
virtual void	stopExecution ()
	If the implementation supports asynchronuos execution, deactivate it.
Signals inherited from ScriptingEnv
void	error (const QString &message, const QString &scriptName, int lineNumber)
	signal an error condition / exception
void	print (const QString &output)
	output that is not handled by a Script
Protected Attributes inherited from ScriptingEnv
bool	d_initialized
	whether the interpreter has been successfully initialized
ApplicationWindow *	d_parent
	the context in which we are running

PyObject * PythonScripting::eval	(	const QString &	code,
		PyObject *	argDict = `NULL`,
		const char *	name = `"<scidavis>"`
	)

evaluate a Python expression

Evaluates code, using argDict (borrowed reference) as local dictionary or an empty one if argDict==NULL. name is the filename Python uses when reporting errors. Returns a new reference; NULL means caller has to do exception handling.

References globals.

bool PythonScripting::exec	(	const QString &	code,
		PyObject *	argDict = `NULL`,
		const char *	name = `"<scidavis>"`
	)

execute a sequence of Python statements

Executes code, using argDict (borrowed reference) as local dictionary or an empty one if argDict==NULL. name is the filename Python uses when reporting errors. A false return value means caller has to do exception handling.
