Creating bpy.types

Code example for creating a new bpy.types

from bpy.props import *


class SCENE_PT_testPanel(bpy.types.Panel):
    bl_label = "Test Panel"
    bl_space_type = "PROPERTIES"

        col.label(text="First Col :)")
        #showing the values of the new type
        col.prop(scene.theData, "TreeName", text="Name of the Tree")
        col.prop(scene.theData, "ValueA", text="FloatValue")

#### constructing a new bpy.type

#### linking the new type to the type.scene
bpy.types.Scene.PointerProperty(attr="theData", type=dataStorage, name="storingData", description="stores some data")

#### adding properties to the the type
dataStorage.FloatProperty(attr="ValueA", name="ValueA", default=1.5,
