QtQuick - Busy Indicator

nvharisha

Hi,

we have a Qt5.4 with QtQuick running on a MIPS platform. We use QML application. We have busy indicator, when ever the data from network is yet to be received.

BusyIndicator {
     id: loadingIconId
     objectName:"loadinglcon"
     x:500
     y:300
     visible: false
 }

But it gets jerky when there is some activities.
As there is network activity, as well as some other activities going on, we thought UI ‍thread might get stuck / busy processing the events and hence we wanted to move to Render thread and hence we used Animator. (

Image{
       id: loadingIconId
       objectName: "loadinglcon";
       x: 875;
       y: 340;
       height: 100
       width: 100
       visible: showHideIndicator;
       source:"../images/busyindicator.png"
       RotationAnimator {
               target: loadingImageCustom
               from: 0;
               to: 360;
               duration: 500
               loops: Animation.Infinite
               running: showHideIndicator
           }
   }

But we are still seeing the same issue. Any suggestions?
Is there any thing that is causing issues in scenegraph rendering? How can we investigate?

We need to run the Loading-Icon till all the data has been received/loaded.

Thanks

Jerk indicates the still UI thread is busy processing. Just a suggestion. How about moving the processing the data itself to different thread & communicate using the signal/slots across threads ?
