Which Qt version to install?



  • I have Windows 7 Home Premium 64-bit and figure I should install one of these versions:

    1. Qt 5.1.0 for Windows 64-bit (VS 2012, 525 MB)
    2. Qt 5.1.0 for Windows 64-bit (VS 2012, OpenGL, 522 MB)

    Correct? But which one?

    I found this information:

    "The Windows offline installers are by default ANGLE based. If you want to know more about the differences between ANGLE and OpenGL packages on Windows, please visit Qt 5 on Windows ANGLE and OpenGL."

    So since the second one says Open GL, is the first one then ANGLE Based?

    1. Qt 5.1.0 for Windows 64-bit (VS 2012, 525 MB) = ANGLE Based?
    2. Qt 5.1.0 for Windows 64-bit (VS 2012, OpenGL, 522 MB) = Open GL (Probably)?

    Which one is the best to use for me as a developer? What is best for the end user?

    Hi,

    Yes, the first one uses ANGLE.
    Which one you choose depoends on what do you want to do with it, which components will you use and what type of comuters you expect your users to have.

    Here's a wiki that might help you decide: "Qt 5 on Windows ANGLE and OpenGL":http://qt-project.org/wiki/Qt-5-on-Windows-ANGLE-and-OpenGL



  • OK, thanks for the response.

    So the recommendations says for example:

    "Use Desktop OpenGL if:
    Your application does not use OpenGL at all (since ANGLE implies additional deployment dependencies which are then not needed)."

    I'm not sure if I will need to use Open GL at all for my project, because it's definitely not a game I'm aiming to develop, but will have some drag n drop functionallity.

    Still, I think that ANGLE seems to be the best option considering:
    "You have a heterogeneous user base with different Windows versions & graphics cards".



  • Hi, IMO, it doesn't matter which one choose. You can even using the former version to debug your code, then using the latter to release your code, or vice versa.



  • OK, sounds good!
