c++ - SOLVED: Destroying thread and exiting loop -

-

i'm creating thread this:

main.cpp

    qthread acceptorthread;     acceptorobject acceptorobject;     acceptorobject.setupconnections(acceptorthread, simulation);     acceptorobject.movetothread(&acceptorthread);

acceptorobject.cpp

void acceptorobject::setupconnections(qthread& thread, simulation * simulation) {     qobject::connect(&thread, signal(started()), this, slot(acceptnewclients())); }

acceptnewclients() method works in infinite loop. @ point if close program error: 

qthread destroyed while thread still running

i looked through similar problems @ stack , 1 guy said need break loop before finishing thread in order rid of bug. suggested use flag in infinite loop , emit signal in destructor change flag , break loop. kinda worked when did this:

qobject::connect(&thread, signal(started()), this, slot(acceptnewclients())); qobject::connect(this, signal(finishthread(bool)), this, slot(acceptnewclients(bool)));

and emited finishthread(true) signal destructor directly changed flag. of course changed slot signature won't run in new thread anymore.

destructor code:

emit finishthread(true);  this->thread()->quit(); if(!this->thread()->wait(3000)) {     this->thread()->terminate();     this->thread()->wait(); }

how can make work?

what i've tried far:

  • adding new slot change flag. result: when close program window dissapears proccess still running. think destructor destroys object before emited signal proccessed .
  • making bool argument in acceptnewclients() slot default one. result: overloads funtion 1 run in different thread , second 1 tries change flag doesn't work because different functions.

solution:

connect(this, signal(finishthread()), &thread, slot(quit())); connect(this, signal(finishthread()), this, slot(deletelater()));

it pointless change slot function signature in case. in deconstructor emit finishthread() signal, nothing more.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
