It may be possible, but not easy, since the font size must be extracted from
the 'guifont' option, and the latter has 5 incompatible formats, viz. GTK+2,
kvim (obsolete, but some versions are still around), Photon, other-X11 and
other. Each version of gvim accepts only one of these, and some have the size
at the end, others have it in the middle, and for a few it can be either. So
you would need to:
(1) construct a function to:
(1a) extract the size from the 'guifont' depending on the current version and
platform;
(1b) increase or decrease the size by 10 (ten tenths of a point) for
other-X11, or by 1 (1pt) on other GUI flavours
(1c) reconstruct the new 'guifont' value
(2) make mappings for <C-MouseUp> and <C-MouseDown> to call said function with
an argument of +1 or -1
It would be much easier to directly edit the 'guifont' on the command-line,
using
:set guifont=<Tab>
where <Tab> means "hit the Tab key": when you hit <Tab>, Vim will fill in the
current value with escaping backslashes if and where needed; you can then edit
it in-place, then hit Enter to accept the changes or Esc to reject the changes.
Here are the possible formats:
has("gui_gtk2")
:set gfn=Andale\ Mono\ 11
11pt "Andale Mono"
has("gui_kde")
:set gfn=B&H\ LucidaTypewriter/9/-1/5/50/0/0/0/1/0
9pt "B&H LucidaTypewriter"
has("gui_photon")
:set gfn=Courier:s10
10pt Courier
has("x11") && !(has("gui_gtk2") || has("gui_kde") || has("gui_photon"))
:set gfn=-*-lucidatypewriter-medium-r-normal-*-*-95-*-*-m-*-*
9.5pt LucidaTypewriter
!has("x11")
:set gfn=Courier_New:h12:cDEFAULT
12pt "Courier New"
Best regards,
Tony.
