Detailed Description

Python Widget This class is a Window for a Python interpreter interface. So it is possible to access all data in the running application in realtime with the script language. PyWidget also has the capablities to run a Python script from a file at startup, or on demand from the user.

Constructor & Destructor Documentation

BALL::VIEW::PyWidget::PyWidget	(	QWidget *	parent = `0`,
		const char *	name = `0`
	)

Standard constructor. If the widget is part of a BALL MainControl widget, it inserts a menu entry Tools|Restart Python into the menu bar.

Parameters:

	parent	the parent widget
	name	the widget name

BALL::VIEW::PyWidget::PyWidget ( const PyWidget & p )

only needed for Pyhon Interface
