[Bf-python] Saving a pointer to another object as a property

[Michael Kleiber]

Hi all,

I would like to save as an object's property a link/pointer to another 
object. I want to display a UI element that lets the user choose an 
object and which will then be saved as a property of the currently 
selected object.

I only succeeded in showing a UI selection element which saves the name 
of the selected object as a string. This means when the user changes the 
name later, the name will be invalidated.

How can I save a pointer to an object?

Kind Regards,
Michael

Example code I use to get the objects name. The commented out parts do 
not work.
 >>>

import bpy

bpy.types.Object.myName = bpy.props.StringProperty()
#bpy.types.Object.myLink = bpy.props.PointerProperty(type=bpy.types.Object)

class GetObjectByPointer(bpy.types.Panel):
     bl_label = "Save Object Pointer"
     bl_space_type = "VIEW_3D"
     bl_region_type = "TOOLS"
     bl_context = "objectmode"

     def draw(self, context):
         layout = self.layout
         col = layout.column(align=True)
         col.label("Select objects to get a link to")
         col.prop_search(context.object, "myName", bpy.data, "objects")
         #col.prop_search(context.object, "myLink", bpy.data, "objects")
