How can I automatically close preview window after I move cursor to another window in Vim?

Question

I would like the preview window disappears automatically when cursor is not in the preview window or preview window loses the focus. Is it possible?

@sidyll No, I don't use Netrw. I wrote a client of twitter-like service in Vim, I use preview window to display timeline. Now I want the preview window closes automatically when cursor moves to another window. — Vayn

Sorry, initially I though you were referring to the preview that netrw and also NERDTree have on files. — sidyll

You may want to have a look on autocommands. A simple example would be:

autocmd WinLeave * pc

Which calls pc (close preview window) every time you leave a window. A more involved example could use a separate function that performs extra checking:

autocmd WinLeave * call ClosePreviewWindow()

function ClosePreviewWindow()
    if &pvw
        pclose
    endif
endfunction

Check :h autocmd.txt to learn more. This file has a complete listing of autocommand events in section 5, so you can choose the one that fits better.

Thank you, autocmd.txt is too long so I didn't read it before. BTW what's the meaning of "&" here?

@Vayn haha that's the only problem with Vim's help: too much information :-P The & is used to echo the option value. Any option should work. It kind of "converts" the option to a variable. You can try :echo &tw for example, which echoes the value of tw. Check :h expr-option
