insert_element and delete_text working problem #631

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
While using pyglet's document, layout, etc. I came across 2 issues:
1) using insert_element function doesn't work as expected until 
layout.begin_update and layout.end_update functions are used around it
2) deleting element from document doesn't reset its internal variable 
_position, which raises an assertionError when inserted repeatedly

Both issues is possible to simulate in the attached code. First simply by 
commenting layout.begin_update and layout.end_update functions from around the 
insert_element function (for ex. rows 16 and 27). Second by commenting the row 
22 (element._position = None).

Deleting row 22 in attached file causes traceback:
Traceback (element._position isn't reset to None manually):

I found another problem concerning insert_element: it raises an attribute 
exception when 2 elements are inserted one after another (without using 
insert_text in between)

It is possible to replicate the issue by commenting the row 28 in the attached 
file imageTest4.py.
