@sp3x said in QVariant: unknown user type: @Christian-Ehrlicher said in QVariant: unknown user type: qRegisterMetaType Thank you very much. That's working. I've already played around with qRegisterMetaType but I missed to pass the right argument to the function ("Widget::HostsTableWidget::HostList") Yes, it should/must be the fully qualified name.

@DrewB Does this behave any differently from the clearer QIntValidator?

@Chris-Kawa omg it worked bro thanks alot!!

@AnneRanch said in "does not refer to a value" error: // event void MainWindow::newSubWindow(void) connect(this,SIGNAL(addSubwindow()),MainWindow,SLOT(newSubWindow())); //&MainWindow,SLOT(newSubWindow())); emit addSubwindow(1); What file/class we are in here? (i.e. what is this?). If this class doesn't have access to your MainWindow object, that you want to connect, this can't work. I doubt, that your object pointer is called/spelled MainWindow. And if it does, it would be very confusing.

@JonB Thanks for your reply! My goal is to draw a filled triangle like this: [image: 4f650996-8c43-4745-ab2c-97adac261555.png] The only way I'm able to achieve this that I draw two shapes: one fills the whole boundingRect() and a second one draws the outline in boundingRect() adjusted by the pen width. I'm not sure that it's a good way to solve this problem. Any tips?

Thank you all for this. I was expecting that I needed the '0' fillchar to fill at the end as well, but I was clearly wrong there. This helped me a lot.

@J-Hilk said in Wrong enum value from QSettings using Qt 6: because I don't remember it ever working without the Q_ENUM macro? It worked in Qt5 so it's a Qt6 regression. And it is very surprising because QVariant<int>() properly converts to an enum whereas QVariant<QString>() did not.

As you already wrote it's an array, not an object, so use the correct function. And please do not post screenshots but text.

Update: Looked at debug output of both apps.

I have changed "my architecture" and decided to pass only part of the data - QList. //LocalAdapterAddressList FSLA = new Form_SetupLocalAdapter(); // LocalAdapterAddressList); FSLA = new Form_SetupLocalAdapter(LocalAdapterAddressList); // &LocalAdapterAddressList); FSLA->show(); i also added a constructor to process the passed data (pointer ) public: explicit Form_SetupLocalAdapter(QWidget *parent = nullptr); explicit Form_SetupLocalAdapter(QList <*data_list>); //LocalAdapterAddressList Now I am getting this error /mnt/07b7c3f8-0efb-45ab-8df8-2a468771de1f/PROJECTS/RECOVERY/BLUETOOTH/SOURCE/CCC_SOURCE/terminal_SERIAL_BLUETOOTH_VER_1/terminal_SERIAL_BLUETOOTH/terminal_BLUETOOTH/form_setuplocaladapter.h:17: error: use of undeclared identifier 'data_list' In file included from form_setuplocaladapter.cpp:1: ./form_setuplocaladapter.h:17:45: error: use of undeclared identifier 'data_list' explicit Form_SetupLocalAdapter(QList <*data_list>); ^ I am not familiar with "template" and have no idea how to fix this. I have been RTFM and have not found a single example of passing template variable (object) as a parameter . All examples are about HOW to build template class. I do not need that, I already have a class I want to reuse.

ok. go for it. I don't see an addressable question here.

@MEsc Check Archive and then press Filtern button. You will get all the stuff of 6.4.0. Sorry. you are doing on Windows. Things could be different.

Even the topic is old I think the problem was fixed with KB5022282 on January, 10th 2023.

@hkottmann said in Byteordermark is not set in *.csv file: Rapidcsv was the evildoer But how did this differ between Qt versions, 5 vs 6?

@Chris-Kawa I guess I should put the left widget outside of the splitter. Thanks.

@masa4 said in QGraphicsView changes on scene does not reflect: ui->graphicsView->centerOn(ui->graphicsView->x()/2,ui->graphicsView->y()/2); But image still not centered. @JonB said in QGraphicsView changes on scene does not reflect: For your actual code (a) it's not what I suggested to use and (b) I don't know what you expect it to do. I already wrote the above previously.

@JonB @jsulm @Christian-Ehrlicher @mpergand thanks for your help, i appreciate you

@jsulm , thank you very much! And thank you, @Christian-Ehrlicher , very much as well!
