Comment #1 on issue 304 by reiner.p...@gmail.com: Entering the command-mode
moves the window (in Pango)
http://code.google.com/p/yi-editor/issues/detail?id=304
I've attached a patch which fixes this.
The problem was as follows. Before this patch, tabs were simply represented
as (PointedList Window), and had no id key (unlike windows and buffers).
This means that, when window focus is changed, the pango UI interpreted the
result as a *completely new* tab, and reconstructed all the UI elements
from scratch. In particular, the drawing window was reconstructed and given
size 1x1. In order to keep the cursor visible in this 1x1 screen, the
window was forced to scroll.
The solution is straightforward: add a genuine Tabs datatype, which
includes an id key for the tab. The pango UI now uses this id key for
synchronisation. The change also saves some redundant reconstruction of UI
elements, for the above reasons.
