Answer 1

Just for new comers: as of now, there is getwininfo() which returns dicts containing key quickfix which can be used for the check. Also note the loclist key.

Since getwininfo returns a list of dict, you may use:

getwininfo(win_getid())[0]['quickfix']

which is 1 when it is a quickfix or location list window. And

getwininfo(win_getid())[0]['loclist']

which is 1 only when it is a location list.
