@Rich-Bair said in QObject Pointer deleteLater() Question: Also, is it safer to break all connects first using disconnect(&ptr, nullptr, nullptr, nullptr) before deleteLater()? The QObject destructor handles disconnecting connections to and from the object.

Hi, Because you can't copy QObject based classes. You should allocate your model on the heap and your property should return a pointer to a QStringListModel.

RHEL is not the only one that is not working. KDE Neon is also concerned. I do wonder if it's not related to the commented out code that you can see in the patch you linked.

Thank you so much for replying! I actually tried to do it this way when I had just started using QT and was unable to so I wanted to confirm I wasn't doing it wrong before attempting again. It worked now. Thank you so much!

Update: I really think @JonB is right, it's was a Windows behavior rather than Qt's. After switching back to VLC as the default app for .mkv, calling the function opens file every time.

Does SLC.exe exist in that folder? You probably had a build failure; try to build your project again and see if there are any errors from that.

Ah I see. I was just trying to remove the border lines of the QGroupBox. I didn't realize that affected the buttons as well. Thank you, that solved it.

You can compose a new image. Fill it with black and draw your thumbnail on top of it.

Hi, The most usual way to do that is to run the ping command using QProcess.

@JonB said in QPushbutton using method?: @Endorfin35 No alternative, you absolutely should put a slot on the button click and set the label text there as you describe, this is the correct paradigm with Qt. This is my answer. Thanks guys.

@hskoglund 'blockSignals(true)' works, this function does not trigger procession of the event queue. Thank you for this suggestion!

Another alternative is KTextEditor/KTextWidgets from the KDE API If you want to implement it yourself a good starting point is the Syntax Highlighter Example

My bad. The Bluetooth and SerialPort modules are now separately downloadable under "Additional Libraries" under Qt 6.2.0 in the Maintenance Tool. Downloaded them and now works. Thanks!

@jsulm , thank you, I will add setAutoDelete(false) to the constructor.

Yes, of course it depens on physical conditions that influences to how many resends do it have in normal conditions. In ideal conditions will be faster but if there are resends it could be worst.

@jsulm said in No eventLoop and direct connection: @Drazz Do you really need a thread for that? How much work is this thread actually doing? Yes! It's computing images from 3 RGB cameras. One thread takes images next does the analysis and next writes outputs. I'm not using signals and slots to have control of queues sizes.

You are a god! I had absolutely no idea what was causing that error.

@harlamer Without a minimal compilable example that demonstrates the problem there's not much we can do. We do not know what platform, what font, what texture and texture setup, how the painter has been set up, what "displayed correctly" means, etc.

Hi You need to compile your app ON windows. then you can use windeployqt You cant directly from linux as it don't have the DLLS for windows versions.
