I didn't go through all of your code...

My guess though is, that even though you've replaced the widget in the layout, window.txt_line_1 still points to the deleted object. So, in your replacement-procedure you'll also have to update this attribute.

So, adding

setattr(parent, obj_name, qt_obj);

to _replace_qlineedit_from_gridlayout might do the trick.
