Hello,
I created this patch that creates a screen object in the python
vim module (vim.screen) with the following members:
.puts(row, col, attr, str, line=-1)
.getHighlightAttr(name)
.mousex
.mousey
This patch enabled me to create text menus and popup lists for both
vim and gvim (vimuiex, script 2606). It's not perfect (a lot of
redrawing, new event loop), but I find it very useful. Maybe
somebody else will, too.
Thank you for vim,
Marko Mahnič
