@hskoglund said in Connecting problem <unresolved overloaded function type>: the parentheses are optional Wow, really? I never knew that!

@nagatofujirama said in QScrollArea: the group box itself should stretch Then use layouts: https://doc.qt.io/qt-6/layout.html

I forgot to close this since I already fixed the issue even though it was a bit of a dirty fix. I just did: "connect(ui->plainTextLines->verticalScrollBar(), &QScrollBar::valueChanged, this, &MainWindow::handleLinesScroll);" and in the handleLinesScroll I just set the scroll bar to the value it was before. But it works flawlessly and I see no performance impact.

Embedding the fonts worked perfectly well. Thank you!

Hi and welcome to devnet, Use the itemsExpandable property to disable it.

@SGaist Oh I see! Thank you, that was helpful. And you bring up a great point - I'll separate them into two applications. Thanks!

@JacobNovitsky said in Could not build QClipboard base sample: it does nothing atm Like @SGaist mentioned, you somehow removed the @JacobNovitsky said in Could not build QClipboard base sample: return a.exec(); you had already in there before. This spins the Qt event loop. With the changes I made to your QLabel you should see at least the label on your screen.

Hi and welcome to devnet, To your last question, yes you should move to CMake. There have been new features added in Qt 6 that will likely be of use for your project but that are only available through cmake. As for examples... maybe check some of the KDE's core projects. They already use CMake and some mix QML and C++.

@JonB thanks for your input :) I found the source of my problem. It's how I handle my data in the model. The data behind anotherModel->getLastEntryTS(clientId); changes whenever a client in the same tableview is selected. It basically only contains the selected client's data. So when the cursor is moved to a different row (another client), the old "green" row stays "green", because the view is not updated for that old row. But when the cursor moves back, the data for the "old" client isn't present anymore and therefore I can't read a correct timestamp from the model. Maybe my mistake helps someone else but I have my doubts^^

Hi and welcome to devnet, Well owning or not depend on your use case. That said, in your case, it seems that the model will be a wrapper on top of your data. In that case, there's a need to implement the model functions to forward the manipulations to your data structure (for example new rows insertions, removal, drag and drop, etc). You should also add adequate APIs that allows external changes to the data structure to be propagate through the model (for example when some data is changed).

@Seb-Tur TRUNCATE commits any existing transaction. DELETE FROM TABLE does not. I would expect ALTER TABLE auto_increment =1 to do same if it is a statement that alters a table's auto-increment column in your SQL. Any DDL-change-type statement is likely to do so.

@Pl45m4 Yes, Qt was previously in Turkish. But right now I'm using it in English. I think there may be a mistake about the Region (such as Turkey, America, England), I don't know. Thank you

@Christian-Ehrlicher Hi Could you please help me to solve the problem on embedded linux system? Here is the information for you: [image: 19f977dc-e8c8-4902-a8f5-956d860f677f.png] the plugin could be found but it couldn't be load by QNetworkInformation::loadBackendByName(QString("networkmanager")) or QNetworkInformation::loadDefaultBackend() Let me know if you want to get other information for you. System: Yocto Linux 5.15 with Qt 6.4.2

@ChrisW67 said in QSqlDatabase and power saving mode: This is Microsoft SQL Server. I misread the OP's original MSSQL-Server as MySQL-Server!
