General and Desktop

At least it's much easier to have two.

Hi and welcome to devnet, What version of Qt ? On what OS ? What is MainWindow ? Please provide a complete minimal compilable example that reproduce the behaviour so that people can test. On a side note, QGridLayout *gLayout = new QGridLayout(this); already applies the layout on the widget represented by this therefore this->setLayout(gLayout); is redundant. If MainWindow is a QMainWindow, then you can't apply a layout on it because it already has one that provides all the bells and whistles of that class.

Are you building for Yocto (embedded Linux) targets? If no, then don't use instructions on how to set up for Yocto development. It won't help you get local dev env for Qt development.

Hi @PRSurface, it seems you did not select a Qt version in the installer. If you want to use MinGW, you should select a Qt MinGW version with the same bitness as the compiler. This should set up everything correctly. Regards

@Isidro-Perla Take a look at this example: https://doc.qt.io/qt-5/qtwidgets-draganddrop-draggableicons-example.html

Just for the sake of building the idea: List Node would only be a list showing something from your data class or should it already a tree ? Do you have a data structure for these external data to be stored ? The basics of your data method looks good.

Hi, You're question is not really clear, to which of your two applications do you want to add something ?

Dear mrjj thank you for your help which gave me some ideas, finally I've found this here: https://forum.qt.io/topic/53447/solved-changing-progress-indicator-in-qprogressbar which helped me to get a better than excepted result

@Mikeeeeee said in windeployqt does not collect the dll: The documentation does not say what path-to-app-qmlfiles is. Well it could not as its where you place them. Often in the project folder with the other files of the project.

@enne9 You are welcome.

@marcmarc Create a filo queue and add the triangles. Draw then while moving and clear the queue when movement stops.

@Binary91-0 said in QListWidget::addItems() Data type question: In the function call, it doesn't work. You don't do this in the function call (as I already said) - you do const TreeItem *myItem = this; TreeItem *myNonConstItem = myItem; And, as I already told you, is not allowed since this would kill the whole idea of const.

@mrjj thank you Video helped me to remember what XOR. Also now it I understand how to easilly transform binary data representation to decimals :)

Hi and welcome to devnet, That's the kind of question your should bring to the interest mailing list. Note however that beside the Metal VS OpenGL issue at hand, AFAIK, the current policy is to follow Apple support plan which means the three last version of macOS. Therefore, depending on what version of macOS you'd like to support, you will have to use an older version of Qt or rebuild it yourself with the "oldest enough" macOS version that still works.

The programmer of simple-mail provided a fix, now it compiles fine. The only thing a had to do additionally was to install openSSL

Hi Are you talking about [image: HZMTcP.png] Anyway, QMenu dont have many options for how it draws so you must use a proxy style to change it. https://stackoverflow.com/questions/59218378/qmenu-right-align-text and for the size, i think you need to subclass QMenu and change sizeHint()

@npatil15 well QDataWidgetMapper must be able to map the QVariant to the widget so it only works with Widgets it understands. If we really want the widgets to also do data processing behind the scene and not just editing then you need to give it access to the model directly if QDataWidgetMapper editing is not enough.

Even better, QPalette QApplication::palette(const QWidget *widget), https://doc.qt.io/qt-5/qapplication.html#palette If a widget is passed, the default palette for the widget's class is returned. This may or may not be the application palette.

I can solve the problem. First, I created folder sqldrivers including libqsqlite.so in the app directory (e.x. /data/user/0/com.example.polarislib) and I set permission by chmod 777 to sqldrivers folder and libqsqlite.so file and finally I used the following code in my source where the connection to Sqlite is needed: QCoreApplication::addLibraryPath("/data/user/0/com.example.polarislib");
