Link the text content of two text objects

Question

Is it possible to link text objects in such a manner, that changing the text content on one object will automatically also change the text of another text object.

To clarify, I do not want to link any other properties of those two objects (like fonts for example), only the source text.

is that for animation or during editing ? – Chebhou May 09 '15 at 20:09 — Chebhou, May 09 '15 at 20:09
During editing is enough in this case. – Antti May 09 '15 at 20:13 — Antti, May 09 '15 at 20:13

this a script that uses the scene update handler to synchronize two text object content :

select the two text objects only
copy and paste the script and click run
once you edit one of the text objects the other one will get updated accordingly

import bpy

obj1 = bpy.context.selected_objects[0].name
obj2 = bpy.context.selected_objects[1].name

def link_text_objects(scene):
    obj = bpy.context.active_object
    if obj.type == 'FONT':
        if obj.name == obj1 : 
            scene.objects[obj2].data.body = obj.data.body

        else :
            scene.objects[obj1].data.body = obj.data.body

bpy.app.handlers.scene_update_pre.append(link_text_objects)

Nice! This does what I need! To make it more universal do you think it would be difficult to have it affect any number of selected objects (instead of just two)? – Antti May 09 '15 at 20:45
maybe will be done with a group , you may want to check this http://blender.stackexchange.com/a/26722/5113 – Chebhou May 09 '15 at 20:52

In case somebody is looking at this with Blender 2.8. @Chebhou's script still works if you replace scene_update_pre with depsgraph_update_pre. So it's this:

import bpy

obj1 = bpy.context.selected_objects[0].name
obj2 = bpy.context.selected_objects[1].name

def link_text_objects(scene):
    obj = bpy.context.active_object
    if obj.type == 'FONT':
        if obj.name == obj1 : 
            scene.objects[obj2].data.body = obj.data.body

        else :
            scene.objects[obj1].data.body = obj.data.body

bpy.app.handlers.depsgraph_update_pre.append(link_text_objects)

Following @Chebhou's and @Marc-Chéhab's answers, I adopted this script for any number of selected objects. It should work with Blender 2.8+.

import bpy
objs = [obj.name for obj in bpy.context.selected_objects]
def link_text_objects(scene):
    obj = bpy.context.active_object
    if obj.type == 'FONT':
        for o in [o for o in objs if o != obj.name]:
            scene.objects[o].data.body = obj.data.body
bpy.app.handlers.depsgraph_update_pre.append(link_text_objects)
