General and Desktop

@mranger90 thanks yes that would be an issue wouldn't it. I'm a C programmer that's rather new to C++, I was actually reading about construction order but had it mixed around in my head. This makes sense, thanks!

@mrjj said in Getting the signal when a checkbox is toggled in a QtableWidget: Im asking as using the View version of List and Table actually allows to share a model between them so if one sets check on some item, it will also show checked in the other. automatically. Ooohhh! :) But I don't quite get why you'd use it? By the time you can select/check something in the TableView anyway, why do you also want a ListView to select/check as well?

alternatively: QTimer::singleShot(100, ui->pushButton, std::bind(&QPushButton::setDown,ui->pushButton,false));. You don't need a lambda to just forward a call to another method

@raven-worx ok, great, thanks! @raven-worx said in Using QStyleWindows created from QStyleFactory::create kills app with Segmentation Fault: ah yes, i knew i read that but couldn't find it on a second glance. IIRC the fusion style was introduced in Qt 5 I'll give it a try once I'll find the energy to upgrade to Qt5. :)

@pas059 Glad you're solved. I'm no expert either, plus I don't use Qt Creator/C++/builds/makes/.pro etc. :) But I think putting that QT += network into your .pro does more then just the LIBS += -lQtNetwork. For example, if QAbstractSocket stuff is in an additional network library file, QT += network may cause extra stuff to be brought in, or flags, or whatever....

Hi What about its ReadOnly property? dateEdit->setReadOnly(true);

@sierdzio : @thanks

I found a solution: Use this code in the part where you want to show the window: if (QApplication::desktop()->screenCount() > 1) { myWindow->setGeometry( QStyle::alignedRect(Qt::LeftToRight, Qt::AlignCenter, myWindow->size(), QApplication::desktop()->availableGeometry(0))); } myWindow->show(); This solves my problem

Yet another proof that 5.12.0 was a big mistake :-) OK good that things work for you now. Happy coding!

@krzysieklfc said in Gamma correction for display: Shouldn't Qt somehow handle the color correction when I'm 'telling it' to view the image? no! why should it? I don't quite understand why you are dividing by 256? Also whats the returning type of GetR()/GetG()/GetB()?

There is no support for such stuff, but some of your information can be gathered: PK: QSqlDatabase::primaryIndex() Column types: QSqlDatabase::record()

Take a look at the Qt documentation of the respective modules in the Qt version you are using, you'll see there which version you can use.

@yogis40 said in Menu without action: Regarding the UI guidelines, I’m interested to found it. As mentioned previuously, I’m newbie in Qt and the last time I’ve programmed a UI it was in Visual Basic in 2004. Then, 15-years ago... There's per platform: KDE's human interface guidelines Apple's human interface guildines for macOS Apple's human interface guildines for iOS Apple's human interface guildines for tvOS Windows desktop guideline

@efjellanger Hi The buttons and menus are first added in section "Adding User Interaction" So first after than your .h file will have private slots: void newDocument(); void open(); void save(); void saveAs(); void print(); void exit(); and the other elements.

how about changing to MinGW 64 ?

@asc7uni Given that we have now proved it works after a delay. I don't know, this is a guess, but it might be that the resizing does not work till the new row has been shown, because something about that is required to determine the size. In your slot can you do some kind of .show() on the table view just before the resizeRowsToContents()? [There's no point asking me more about this, you'll have to try whatever you can find and see.]

@Nio74 It's a header only library, so download the headers put them somewhere, then add the directory where the headers are to INCLUDEPATH variable in your pro file (see http://doc.qt.io/qt-5/qmake-project-files.html). For everything else you should read the documentation of that library.

@jsulm actually socket creation itself is a problem server_fd = socket(AF_INET, SOCK_DGRAM, IPPROTO_IP) here server_fd is -1
