[SOLVED] Several Qt problem on BB Qt



  • I don't know...I've given it up for now...I'm using cascades for this simple project (just qml, javascript and sounds using multimediakit).
    It was wonder if I could use qtcreator with just few port hours...but it wasn't!
    Anyway I will give a try to it...
    Does Someone know if NumberAnimation and PropertyAnimation are supported?



  • bq. Does Someone know if NumberAnimation and PropertyAnimation are supported?

    Yes, of course.

    Setting up the Qt Creator with BB10 canbe somewhat anoying, still. But it will improve in the next version.



  • I've just tried again to load the main qml onto device without success!
    the form uses qtmultimediakit and a Rectangle in which I set a background image (get from resource).
    It shows me just a white form (locking orientation on the device; if not it shows half white image and then it crash)!



  • I suspect you either did not package the asset (qml file) correctly or, you specify the wrong path.
    Are you using qrc or are you deploying your files?

    I have used both because of I've two versions: one symbian that deploys all files and an other one for n950 that uses resources. I think the symbian version worked for me (showing background but always in portrait mode).



  • So are you now using qrc or assets now? Is there an error message from the program?

    currently I'm using qrc for images and sounds and I haven't any error from Qtcreator (but if see another my post, I'm not able to launch app directly from within qtcreator, so I suppose I cannot view normal output)



  • What about the qml files...how are these packaged?



  • They are packaged in the normal way...just added in the project file



  • AlterX, bar-descriptor.xml file is important as well. Adding files into pro file is not enough. Look how sample app is done.

    White rectangle means that something has failed to load or there is error

    Choose one orientation in bar-descriptor.xml for now. There is bug (some other recent thread) that prevents orientation change - it is fixed and will be available with next NDK release.



  • I'm creating an app from scratch...ok I'm able to show a background in portrait mode, but when I just put
    @
    import QtMultimediaKit 1.1
    @

    The screen returns to be white (doesn't matter if I put multimedia in .pro file)



  • QtMultimediaKit should be there. However, not everything is implemented yet (like the camera).

    I am getting "module "QtMultimediaKit" is not installed" error.



  • I am getting “module “QtMultimediaKit” is not installed” error.

    Are you using the simulator or a dev alpha?
    Did you set a qml import path in the bar descriptor file?

    I'm using a alpha dev B. What do you mean with set import in bar descriptor?
    I've set qml dir in bar descriptor.



  • Are you having sth like this in the bar descriptor? If the answer is yes, how does this line of code look like? And if no, can you add this line and try it again?

    <env var="QML_IMPORT_PATH" value="/usr/lib/qt4/imports"/>

    Wow...now it works!
    that's very strange; I had the same line but value was "/app/native/imports".
    The other lines are as shown:
    <env value="app/native/plugins:/usr/lib/qt4/plugins" var="QT_PLUGIN_PATH"/>
    <env value="app/native/lib:/usr/lib/qt4/lib/" var="LD_LIBRARY_PATH"/>



  • /app/native/imports is a folder inside your application sandbox. If you don't deploy Qt yourself, than this folder does not contain the plugins. Skiping the line with <env var=“QML_IMPORT_PATH” value=”...> completely should be fine as well.



  • Sorry for digging old topic up.I already copy example code but why i still encounter the same error.The code above seems to be missing "/"

    Example Code
    @<env var=“QML_IMPORT_PATH” value=”/usr/lib/qt4/imports”/>@ //For some reason "/" won't appear beside code but i do put it

    @file:///accounts/1000/appdata/com.Tester.testapp.testDev_xx_testapp35f67ca8/app/native/qml/MyApp/main.qml:7:18: Type Control unavailable
    file:///accounts/1000/appdata/com.Tester.testapp.testDev_xx_testapp35f67ca8/app/native/qml/MyApp/Control.qml:3:1: module "QtMultimediaKit" is not installed @



  • A new snapshot (Qt 5.2.1) is available for BB "here":http://qt-project.org/wiki/Qt5-on-BlackBerry10
