QUrl Class's *addQueryItem* method

I want to query the Google map for all the roads leading to a given GPS coordinate.

For that I'll have to place a "query" which can be done by: http://doc.qt.io/qt-4.8/qurl.html#addQueryItem

Now I want to know how to figure out that what should be the key and its corresponding value here?

Should the key be "road"/"roads"? Whats the way to decide that? And I want all the roads not a particular one!

Any hints?

Solution

  • An HTTP URL has the following format: http://some/address?key=value&more=values

    The part behind the '?' is your query. You have to determine how the resulting URL should look like and add key/value pairs accordingly.

    It isn't completely clear to me what you want to accomplish. You might want to check out these Google Maps API Links:
