FeaturePython Custom Properties/it

Segnaposto per descrizioni approfondite delle proprietà delle funzioni Python 

Le proprietà sono i veri e propri mattoni per la costruzione degli oggetti FeaturePython. Attraverso di esse, l'utente è in grado di interagire e modificare l'oggetto. Dopo aver creato un nuovo oggetto FeaturePython nel documento (obj=FreeCAD.ActiveDocument.addObject("App::FeaturePython","Box")), è possibile ottenere un elenco delle proprietà disponibili digitando:

You can get a list of the available properties by issuing:

This code will create an object with internal name (automatically renamed to  and so on, if an object named  already exists) and give it the user-friendly label. This label will be displayed in the Tree view. Expressions can refer to this object by its label using.

is the type of the property. The different types are described in more detail below.

You can also use the short form which omits the last two arguments. The subsection defaults to, and the tooltip is not displayed with this form.

To get or set the property, use :

If the type of the property is App::PropertyEnumeration, the setter has a special behavior: setting a list of strings defines the cases allowed by the enumeration, setting a string selects one of these cases. To set the list of possible cases and set the current one, use:

As of FreeCAD 0.20, you can also group enumerations, which are displayed in the GUI using a submenu interface. To group, use the character (vertical pipe) as a separator, e.g.:

Item A",   "Group 1

The GUI will display this as a menu structure:
 * Group 1
 * Item A

 * Group 2
 * Another item
 * Last item
