align_center_tag is GtkTextTag with this property :
justification=GTK_JUSTIFY_CENTER
I apply this tag to the line of insert cursor with this (python code):
iter_start=text_buffer.get_iter_at_mark(text_buffer.get_mark("insert"))
iter_start=set_line_offset(0) # backwark to the start of line
iter_end=text_buffer.get_iter_at_mark(text_buffer.get_mark("insert"))
iter_end.forward_to_line_end()
text_buffer.apply_tag(align_center_tag, iter_start, iter_end)
After that, when I move the cursor to the end of line, this line change
justification to left. Why this ? I don't understand
Thanks for your help
Stéphane
