    Default Loading images from url in qt 4

    I am very new to qt creator and would appreciate any help you could give me. I am currently using qt 4 and a trying to load an image from a url (https://chart.googleapis.com/chart?c...hl=Hello|World) but I can't find any image classes that would allow me to do this. (This is for a desktop application). Any help or suggestions are appreciated thank you.

    is the url a local file?
    If so, have a look at its docs, you can convert it to a local file which will be taken by QImage and QPixmap.

    Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.

    You first have to download it. See QNetworkAccessManager for a first start.
