Can I change vim completion preview window height?

问题

I'm using Eclimd for completion. it generates a lot of helpful info about function, but in 1-line preview window it looks messy. (same window uses by omni-completion)

So:

1. Is there any way to change default preview window height?
2. Make preview-popup instead of preview-window?

I am facing problems with 'previewheight' too so I came up with the following work around:

set previewheight=50
au BufEnter ?* call PreviewHeightWorkAround()
func PreviewHeightWorkAround()
    if &previewwindow
        exec 'setlocal winheight='.&previewheight
    endif
endfunc

You can change the default height of the preview window by setting the 'previewheight' option.
