Previously SpeedPlotView assumed speed is updated per second but the
default value was 1500ms and that can be further changed by the
user, this caused a lot of duplicate data in the calculation of the
graph points. Now Averager averages based on the target duration, resolution
and also takes into account when actually data has arrived.
Also improved resolution of 6-hour graph, previously it was same as 12-hour graph
Warning from compiler:
speedplotview.cpp:342:63: warning: ‘QPainter::HighQualityAntialiasing’ is deprecated: Use Antialiasing instead [-Wdeprecated-declarations]
Explicit or implicit calls to begin() and end() cause a non-const
container to detach from shared data, ie. to perform a deep-copy to gain
a unique copy of the data.
That can be a expensive although unneeded operation.
In order to assist the developer a copyAsConst function is added.
copyAsConst returns a const copy of the object.
For lvalues just use qAsConst. It's only available on Qt 5.7.0. But we
added also for earlier versions. The developer can always use qAsConst.
Intended uses:
QString s = ...;
for (const auto &ch : qAsConst(s))
process(ch);
for (const auto &ch : copyAsConst(funcReturningQString()))
process(ch);
torrentcontentmodel: Use a variable to store filesCount
optionsdlg: add fallthrough comment to suppress warning
speedPlotview: initialize member
misc: fix wrong type used, add spaces
