~~Jriegel~~ 2011-11-21 08:57 administrator ~0001334	Can reproduce. Seam a problem in serializing the python object. Get the error: PropertyPythonObject::toString: can't pickle FeaturePython objects wen saving the document.

I want to remark that the getIcon method is respected while claimChildren does not seem to have an effect. And I doubt that the pickeling Problem in the view Object is the sole cause. >>> doc.import_dxf.ViewObject.Proxy.Object is doc.import_dxf True

wmayer 2012-04-12 10:52 administrator ~0001928	Minimal example to demonstrate the error: import FreeCAD, FreeCADGui, Part def makeTest(): doc = FreeCAD.newDocument() box = doc.addObject("Part::Box","Box") obj = doc.addObject("App::FeaturePython","Claim") _Test(obj) obj.Base = box _ViewProviderTest(obj.ViewObject) FreeCAD.ActiveDocument.recompute() class _Test: def __init__(self,obj): obj.addProperty("App::PropertyLink","Base","Base", "The base object this component is built upon") obj.addProperty("App::PropertyLength","Width","Base", "The width of this wall. Not used if this wall is based on a face") obj.addProperty("App::PropertyLength","Height","Base", "The height of this wall. Keep 0 for automatic. Not used if this wall is based on a solid") obj.addProperty("App::PropertyLength","Length","Base", "The length of this wall. Not used if this wall is based on a shape") self.Type = "Wall" obj.Width = 0.1 obj.Length = 1 obj.Height = 0.1 obj.Proxy = self def execute(self,obj): obj.Label = "Hello" class _ViewProviderTest: def __init__(self,obj): obj.Proxy = self self.Object = obj.Object def getIcon(self): return ":/icons/Arch_Wall_Tree.svg" def claimChildren(self): return [self.Object.Base] def attach(self,vobj): self.Object = vobj.Object return def __getstate__(self): return None def __setstate__(self,state): return None
