Hi Kim,
ohh! Okay!
Have you tried splice instead?
Array.prototype.splice (start, deleteCount [ , item1 [ , item2 [ , … ] ] ] )
I think maybe something like:
accarr.splice(0,1,<float>)
Looks more neat and it is in the normal javascript canon. Did not find
the documentation on javascript and qt quick in the rush.
Hope it helps you as a work around.

Hi Peter
Why use an array and not a vector or an Hash map?
As far as I know those are not supported under javascript, otherwise a vector
would have been my first choice, an Hash map is overkill for my needs, I only
need to add to the end, and always need sequential read.
I am tempted to move the business part to C++, but I'm trying to do as much as
possible in QML (as an exercise).

Hi
For some time I have been battling a memory leak in my pedometer app,
after a
lot of experimentation, I have found the problem to be my use of arrays
(probably)!
Whenever I receive an acceleration measurement, some statistical
calculations
are made, which results in one float pr. measurement.
As I need the measurements for a certain time for further statistical
analysis, the results are stored in an array, used as an traveling window
like
this:
accarr.shift(); // the array is pre-initialized with empty elements.
accarr.push(<float>);
This works great, but it leaks memory fast, and after some time (between 1
& 2
hours) the OS kills all running apps!
Any ideas how I can solve this?
Thanks.
Kim
