Re: [Interest] server certificate integration
Hi, Why not pass the path to the certificate as a parameter of your application ? That way, you can configure it in the startup script of your server and just need to restart/reload it when the time comes to update the certificate. Another possibility is to use a configuration file in which you point your application to where the certificates are.

Hi,

changed exactly from 10.11 to 10.12 however if interested I have a small patch
that adds the missing imports/includes where needed. It might need some cleanup

Re: [Interest] qt.labs.controls Material Toasts
Hi, Ok, I see what you mean :) I was asking because I've started some time ago to implement (early WIP) a pluggable notification system for Qt so I was wondering if it could benefit to these custom notifications. If interested, you can take a look at https://codereview.qt-project.org/#/c/97068/ It's not ready yet but the more inputs the better :) Samuel On 12 févr. 2016, at 16:17, Nurmi J-P wrote: > Hi Samuel, > > We’ll probably leave the native notification system integration job to the > platform extras or other modules.

Hi, If the system didn't change since last version, the preferences are cached by cfprefsd, so you have to call "defaults delete [your bundle identifier]" on the command line.

[Interest] QStringList, takeFirst and order of execution
Hi,
I have been experiencing a strange behavior with QStringList and the order of
execution of takeFirst.
The following code:
QString line = file.readLine(); // line contains "46 71\n"
QStringList lineData = line.split(); // lineData contains ("46", "71\n")
qDebug() << lineData.takeFirst() << lineData.takeFirst();
behaves differently on two computers.
The first one is a MacOS X 10.8.5 with Xcode 4.6.3 installed and using the
5.2.0 alpha package with gcc
The second one is a MacOS X 10.8.5 with Xcode 5.0.1 installed and a developer
build (no special configuration) of the latest stable branches from git with
clang
The first computer outputs "71\n" "46" and the second one "46" "71\n"
The same happens if I build e.g. a QSize using:
QSize mySize = QSize(lineData.takeFirst().toInt(),
lineData.takeFirst().toInt());
on the other hand, if I call
qDebug() << lineData.takeFirst();
qDebug() << lineData.takeFirst();
The order is correct on both of them.
What could explain the difference ?

Hi,
IIRC, you can't have Item or Holder in a QVariant because there QObject so the
copy constructor is disabled for them.

Re: [Interest] Best way to QObject-wrap simple objects
Hello,
IIRC you don't,
You have to Q_DECLARE_METATYPE your POD, qRegisterMetaType it and maybe
(depends on your use case) add the in/out stream operators (only if you need to
load and store in a QVariant).
Hope it helps

For example: - mycoolproject - apps myfirstapp src test doc mynonqtapp src test doc - libs mycoollib src test doc mynonqtlib src test doc Using that kind of approach allows you to have a flexible development setup (as well as using TDD to ensure the robustness of your code) . All the code you want to reuse goes in a library (Qt or not) and then you application(s) link to these libraries. In the case where you don't want to "pollute" your installation target, simply build you libraries statically. For the non Qt application/libraries simply add CONFIG -= qt and you're done, qmake for build system but no Qt involved.

Hi, As silly as it might sound, why don't you just not add the QDockWidget ? By default at construction time, the QDockWidget is a floater. If you want it to be a QMainWindow children, just make the QMainWindow it's parent. Another thing that might be done is using setFloating() from QDockWidget.

Re: [Interest] How to use unit testing with Qt framework properly
Hi, Using the subdir template, you would only have one project opened in Creator, all the other "subproject" are contained in it. So only one build to manage and you can select which test you'd like to run in the run settings panel. And if you want to run them all every time you build, add a buildstep with "check" as Make arguments.

Re: [Interest] How to use unit testing with Qt framework properly
The best answer i can give you is: it depends. I like to have a test project per class so i can run them manually while writing the related class and have them automatically called when doing automated test procedures. Have a look at the subdir template. Basically, you will end with several subdirs "project" : MyProject.pro -> subdir template apps/apps.pro -> subdir template apps/myapp/myapp.pro -> app template libs.pro -> subdir template libs/xxx/xxx.pro -> subdir template libs/xxx/src/src.pro -> lib template libs/xxx/test/test.pro -> subdir template It is one way of doing it, might not be the best, but works well for me.

Re: [Interest] QSerialport EV_RXCHAR not emitted or catched while moving window
Again: use the readyRead signal ?

Re: [Interest] QSerialport EV_RXCHAR not emitted or catched while moving window
I must say, I don't understand your use of QSerialPort.
You are waiting on data coming from the serial port, aren't you ?
So, why not just connect to the readyRead signal ?

Re: [Interest] Problems with Drag and Drop in Windows 7
In my case they are reached. Are you building your application in debug or release mode ? In release mode, it won't break. Furthermore a line like int n = 0; is likely to get optimized out. If you want to have the correct behavior, do as said in the documentation with the acceptProposedAction() On 25 janv. 2012, at 16:56, noru...@me.com wrote: > But the main problem is that the breakpoint in the functions aren't reached. > > Make a breakpoint on a line (int n = 0;) in the code and run in debug mode > > Am 25.01.2012 um 16:48 schrieb Samuel Gaist : > >> >> On 25 janv. 2012, at 15:44, NoRulez wrote: >> >>> Hello again, >>> >>> I've attached a small and simple example, which doesn't work. >>> >>> Maybe someone could help >>> >>> Thanks in advance >>> Best Regards >>> >>> ___ >>> Interest mailing list >>> Interest@qt-project.org >>> http://lists.qt-project.org/mailman/listinfo/interest >> >> Hello, >> >> Tested with mingw 4.4.0 as well as MSVC2008. >> >> Indeed, your example won't work as it is.

Indeed, your example won't work as it is. You need to accept the proposed action (event->acceptProposedAction()) in dragEnterEvent and dragMoveEvent and just accept the event (event->accept()) in dragLeaveEvent. In dropEvent, you have to do your stuff and again acceptProposedAction(). Hope it helps Samuel ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
