The reason gettabwinvar() doesn't work is that the function returns
window variable not tab variable. The difference between getwinvar() and
this is that the former refers to the current tab, where as you can
specify a different tab using the later.
There is no direct way of accessing this variable, I think this is
lacking, as I was looking for a way to associate buffers to the tabs in
which they are opened (for my selectbuf plugin to have a way to show
only the buffers edited in the current tab). I was thinking of a
workaround in which buffers will have a local variable whose value is
copied from the curret tab. You can probably do something similar using
a WinEnter autocommand, something like:
au * WinEnter :let w:maxd_TabName = t:maxd_TabName
This allows you to use gettabwinvar() function with "1" for winnr.
