Great, thanks for the quick reply and confirmation. One more question: Would you create one QThreadPool instance for the entire application or create new instances as you go (from within different modules). Does it matter? Cheers, frank On 20/01/17 3:29 PM, Thiago Macieira wrote: On

Bob, Thanks to you I achieved my goal, in my last mail about Qt plugins I only had a questions about the diferences of "reinterpret_cas" and "dynamic_cast" which you answered me whit a link of a web page that explain all cast operators of C++. However I will look around your link above and

[Interest] QThreadPool - global instance or custom one

Hi all, I have started using QThreadPool for the first time and am wondering if it's save/recommended to create my own instance of it or to always use the global instance? I.e. the docs all tend to refer to the global instance but they don't say anything about creating your own. Are there

How many platforms are you supporting? None of the platform documentation for mobile is up-to-date. I don't need documentation if I have a tool. Just update the tool because the docs never get updated. > Sent: Thursday, January 19, 2017 at 12:28 PM > From: "william.croc...@analog.com"

Re: [Interest] Qt 5.8.0 RC build under windows

I really think Qt needs a compile tool (like the Linux kernel has/had (make menuconfig or xconfig) ) that will also provide telemetry* when a build fails. I *never* have had Qt "just compile" and these days I'm compiling it for at least 3 platforms. Heck even a make clean doesn't complete

QSignalSpy::wait has a race condition though. When the signal is emitted from a different thread, it might come before you called .wait and then the wait will time out and return false (so it looks like the signal wasn't emitted). You can store the value of spy.size() and after the wait compare it

Re: [Interest] I can´t compile Qt statically (statically link)

Hi, 5.6.2 is not necessarily the best 5.6 option regarding compiling Qt. There is at least a regression between 5.6.1 and 5.6.2 which prevents me building a static Qt with system libpng. https://bugreports.qt.io/browse/QTBUG-57148 It also affects latest 5.7 and 5.8 I'm currently stuck with
