@V0rtex said in Cant emit signal array of structure QList<Structure>: Q_DECLARE_METATYPE(PLC_CONTROLPARAMS_LIST) That's not the type you need to declare. You created a container of those. BTW: please use using instead of typedef to alias the type. using PLC_LIST = QList<PLC_CONTROLPARAMS_LIST >;

Thanks SGaist, it works now! I didn't see that the function itemAt was giving back the pointer.

@JonB This worked for me. Thanks a lot.

Hi, did you also triy "... set the QT_AUTO_SCREEN_SCALE_FACTOR environment variable to 1. " (it's at the bottom of the High-DPI page from @SGaist 's link)

@SGaist Thanks, it worked. I got rid of the while loop and connected the finished signal of QPropertyAnimation to the function of running the programm which runs the rules.

Don't you have access to the source code ? And if not, ask the authors ?

Please post a minimal, compilable example - I really don't know anymore where you added what and why. You posted a working solution so it must be a problem sonwehere in your code.

IIRC, main application window position is just a hint to the window manager, and the manager is free to override the location. What window manager/DE is it being run under? That may give a clue.

@Boman if the tool bar was set using addToolBar(toolbarWidget), you can show and hide the toolbarWidget to achieve your purpose

I found the solution (thanks to your posts). To have a dependency with the libQt5Network library, you just have to add in the .pro : QT += xmlpatterns And in the code: #include <QXmlSchemaValidator> QXmlSchema schema;

@SGaist Thanks! I'll follow you recommendation.

@tux_brazilian said in Multithreading and WebSocket: the server couldn't handle it and disconnected Since you program the server I would guess you're doing something wrong. The server does not disconnect a connection by itself. You must be doing it somehow.

Hi, thank you for your answer, I was wrong with the term slot, I mean signal. I will try it on your suggested way. Thank you!

@AnneRanch said in Please help me find my "connect" error: localDevice connect() needs a pointer as first and third argument, not an object

No, Semester is the parent of Kurs. Semester has a vector of Kurs*, and each Kurs has a poinzter to its parent, a Semester.

@Daddedebad said in QString.append() with a utf8 character not working: B.append(QString("%1").arg(QString::fromLatin1(A.c_str()))); B += QLatin1Char(a[0]); or, when A is more than one byte B += QString::fromLatin1(A.c_str());

@CupofCoffee said in how can i modify the value of the Qjason array?: TradingAreaInfoArr = rootObj["TradingAreaInfo"].toArray(); My understanding is that this returns a copy of the QJsonArray. You can modify that copy (update values, append new ones), but that does not alter the array in the QJsonDocument. The same with the QJsonObject InfoObj = rootObj["info"].toObject(); The objects/arrays in these are read-only. You have to copy them out as above, alter them, and then replace the current objects/arrays in the document, or create a new one, in order to produce a new document with the updates which can be saved.
