function crashes
-
here is the function to update cpu information .
when i open this app 2 at the same time it crashes.void ResourcesPage::updateCpuChart() { static int second = 0; QList<int> cpuPercents = im->getCpuPercents(); QVector<QLineSeries *> seriesList = cpuChart->getSeriesList(); for (int j = 0; j < seriesList.count(); j++){ int p = cpuPercents.at(j+1); for (int i = 0; i < (second < 61 ? second : 61); i++) seriesList.at(j)->replace(i, (i+1), seriesList.at(j)->at(i).y()); seriesList.at(j)->insert(0, QPointF(0, p)); seriesList.at(j)->setName(QString("CPU%1 %2%").arg(j+1).arg(p)); if(second > 61) seriesList.at(j)->removePoints(61, 1); } second++; cpuChart->setSeriesList(seriesList); }HERE IS DEBUG OUTPUT OF THIS ERROR.
@saber said in function crashes:
for (int i = 0; i < (second < 61 ? second : 61); i++) seriesList.at(j)->replace(i, (i+1), seriesList.at(j)->at(i).y());maybe
for (int i = 0; i < std::min(std::min(second, seriesList.at(j)->points().size() - 1), 61); i++) seriesList.at(j)->replace(i, (i+1), seriesList.at(j)->at(i).y());?

I put my money you crash in the
seriesList.at(j)->at(i).y() part. -

Hi
I would insert qDebug() for size() of all lists involved and
also dump the values of i and j.
Its hard to guess at since normally one inspects the runtime variables in the debugger to see if all
are within bounds.what does seriesList.at(j) return ? a QString or list ?

Ok so its a Qlineseries pointer
Looking at its replace, it seems to be this one ?
void QXYSeries::replace(int index, qreal newX, qreal newY)anyway, you can split to multiple statements so its more clear which part that crashes.
for (int i = 0; i < (second < 61 ? second : 61); i++) {
auto Line= seriesList.at(j);
auto value = seriesList.at(j)->at(i).y();
Line->replace(i, (i+1),value );

Hi
Will it work on any linux?
Also, you are trying to fix the
Known Bugs
Opening two dashboard ,crash the whole app. <<< -- that one ?@mrjj
yes it wiil run on any linux. as far as i know.
because it has little dependences(qt,file,libmagic-dev/libmagic-mgc/libmagic1)
and yes for now i want to fix the "Opening two dashboard ,crash the whole app"
but it also have other bugs heremy way to fix all this and add this feature by opening issue in qt forum.
as i don't know the high level coding.i was intendant to do a invitation to join this project in this forum .but i was woried as it will be right way to that.
if you have some time to fix this issue........ -

@mrjj
it is not a bigg project.
me and my friend made this app.
my view , his code. he is has no interest and time for it now.
so what you are thinking to .....@saber
Ok, so you Designed it and he programmed it. sweet.
Currently im spring cleaning pc so i have no linux around before monday.But if its easy to build, i might have a look at that bug next week.
That said i have huge project at work so I cant help program it
like project member. -

@mrjj
thanks for helping.
it is easy to build .just the 2 dependencies .
thats ok ,if you could not join as a project member.
programar like you need little time to solve this listed problems.looking forward to hear for you.
