Structure of the custom widget interface

Description
The library is supplemented by an interface in order to display the custom widget in the dialog.
This contains macro definitions with which "Run MyScreens" initiates the custom widget. The
interface is available in the form of a cpp file. The file name can be freely selected, e.g.:
sleswidgetfactory.cpp
Programming
The interface is defined as follows:
#include "slestestcustomwidget.h"
....
//Makros
....
WIDGET_CLASS_EXPORT(SlEsTestCustom-
Widget)
Example
Content of the file sleswidgetfactory.cpp for a custom widget with the class name

#include <Qt/qglobal.h>
#include "slestestcustomwidget.h"
