@J.Hilk @aha_1980
Something went wrong after switching from 5.12 to 5.13. Probably I selected a wrong configuration 'VS2017 Desktop 64bit'. If I select 'Desktop Qt 5.13 MSVS2017 64bit' the project compiles.

@3cxitalydev Glad you figured it out.

Then please mark this topic as SOLVED. Thanks.

@TTIO said in undefined reference to name::staticMetaObject when registering with qmlRegisterType:

Yeah, it didn't help

The only reason I can think of why that wouldn't help is that moc is not running on your header file. Try removing it from the project and add it back again

By doing it ? Note your indentation is all over the place so it is a bit hard to determine within what you have defined these methods. Going with the assumption that all the methods are directly under the class here is how

def CollectArtifacts(self): self.ZipAllEvidences()

Methods in the same class share the same "self" indicator but if they were not in the same class (or embedded deeper under another method) then you would need to use the handle to the method via its class and/or parent method

Well without seeing a minimal fully functioning example of your code it is kind of hard to guess what you might be doing wrong.

However as a general answer I (unless the combo box has a large amount of data in it) just store this data in dictionary and/or list and then add to the dictionary/list -- purge the combo box -- and add the data pre-sorted back into the combo box

Yes the basic question should be not "How do I remove duplicates from a table view" but more "How do I stop from putting duplicates into a table view". Keep in mind the latter is actually much easier than the former and is the proper methodology. Duplicates (if not desired) should never be allowed into the table view to begin with. If they are getting there then the onus is on the procedures that are responsible for adding data to the table view and that is where you need to fix your code. There are numerous ways to do this one of which has already been suggested. Still the best way for you would be to post your minimal fully functioning code so we can help you redesign it to work properly.

@gabor53
Which Qt version are you using, and what is the platform ?

@SGaist

From the vendor, DLOGIC. They provided the eval board and a VirtualBox VM with the toolchain included.

@LeLev the reply was from Mobile, so it got missed.

@duarna hi
see flowlayout

You can probably use something like: https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System

@NotYourFan Prüfe, dass in Deinem Quellverzeichnis keine Makefiles und keine generierten Dateien vorhanden sind. Also wirklich nur Source-Dateien.

Manchmal hilft es auch Creator zu schließen, die .pro.user und das Build-Verzeichnis zu löschen und dann weiterzumachen.

I installed Visual Studio 2017 and Visual Studio 2019.

Hi,

Then post the stack trace corresponding to your crash.

The real height for such items as Column is stored at implicitHeight property. Just set contentHeight: list.implicitHeight for your flickable.

@yetanotherqtfan https://doc.qt.io/qt-5/qwebenginepage.html#runJavaScript-2

Thanks a lot, that's exactly what I was looking for.

Correct code is:

void IosShareUtils::share(const QString &text, const QUrl &url) { NSMutableArray *sharingItems = [NSMutableArray new]; if (!text.isEmpty()) { [sharingItems addObject:text.toNSString()]; } if (url.isValid()) { [sharingItems addObject:url.toNSURL()]; } // get the main window rootViewController UIViewController *qtUIViewController = [[UIApplication sharedApplication].keyWindow rootViewController]; UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil]; if ( [activityController respondsToSelector:@selector(popoverPresentationController)] ) { // iOS8 activityController.popoverPresentationController.sourceView = qtUIViewController.view; } [qtUIViewController presentViewController:activityController animated:YES completion:nil]; }

Thanks for the help
But it did not work for me :(
It's probably part of the solution, but I think I'm missing something else

@J.Hilk properties

@brucezcg Can you also show how you create the dialog and show it?
If the dialog is empty then most probably your event loop is blocked.

Qt 5.13 is supposed to bring support for the native dialog

@Kira said in Issue in making GUI responsive:

Will this approach cause my GUI to hang if i don't get a timely response??

Not in that example. But again: why not simply use asynchronous API? Why do you make things unnecessary complex?

@NickV said in Qt 5.13.0 - Build postgres driver for android:

/usr/lib/x86_64-linux-gnu/libpq.so

This lib was built for x86_64, not ARM. You need this lib in your sysroot for ARM.

@patrickkidd hi
https://stackoverflow.com/questions/26704621/how-to-create-a-qqmlcomponent-from-c-at-runtime

@aha_1980 said in Is there somewhere a visual inheritance tree of the Qt classes?:

Probably related to the recent QDoc changes that now involves clang for creating the documentation. Maybe a bug?

You're probably right. The doc team has marked this as P1: https://bugreports.qt.io/browse/QTBUG-77126

Finally I builded Qt webengine 5.9.8 with VS 2015 in the windows of English environment, it works OK.
The ninja needs python2, but python2 in the GBK charset environment causes compilation errors.

Maybe I will rebuild Qt 5.13.0 with VS 2017, but not now.

You need a proxy model like Role Mask Proxy Model. You can find an example usage here

Fixed. Use QQuickView instead of QQuickWidget

@SGaist shall i use the function removeRow () in order to remove data from my model? I thought that by removing the data source it would be enought.

Oh right I forgot to mention that I am on linux and qt 5.13. I'll try to see if I can find whether this issue is fixed or not.

@JKSH will try to make the MWE the way you instructed me to do. Thanks. As for the version- I really cant tell, since i prev qt version I was not that far in the project progress...

@Malathi-K Usually the development files have a -dev suffix. But my Ubuntu 14.04 here shows:

apt-cache search qt5 | grep qt5-default qt5-default - Qt 5 development defaults package

so qt5-default should be a good start.

Also note that Qt 4 is already very old and I would not use it for new development.
