@JonB said in Elements added by QtDesigner does not show up in QtCreator: @Noobish Have you (re-)run uic to (re-)generate the (now changed) C++ .h file? No I have not, well not directly any way. Even if I build the client, which I assume would run uic at some step,, I still dont get the new components to show up in Creator when writing code. The mainwindow.cpp file contains the line: #include "./ui_mainwindow.h" I found the the file in build/Desktop-Debug/projectname_autogen/include/ui_mainwindow.h So I guess it is placed in a directory that is not parsed by qt creator? Should I try tell QtCreator to look for source code in that directory also? Or what should I do? I dont want to do some manual labour (well, I could run an infinite loop making calls to uic or watch for the gui file to change, but I'd rather QtCreator would handle that for me automatically.

@Christian-Ehrlicher Thanks, I'll have a go and see if I can figure that out.

As the error message tells you, you forgot to specify the source directory.

Hi, I am not aware of any but from a quick look at the documentation, you can create one factory that returns different sensors. I think you just have to register each passing the same factory.

@IamSumit Upgrade Qt to the latest and you will be able to find enough examples under Examples/Qt-6.9.0/quick3d and Examples/Qt-6.9.0/quick3dphysics

Any professional app worth its salt has a mechanism to create core dumps (mini dump files inWindows parlance). Then you build your executable with debug symbols enabled and when the app crashes on 3rd party machine you can do post mortem analysis based on the minidum and the symbol files.

Hi and welcome to devnet, Did you include the OpenSSL libraries in your apk ?

QTextDocument supports HTML4 markup, you can read this: https://doc.qt.io/qt-6/richtext-html-subset.html The simplest way to show html content in Qt Widget would be using QLabel's setText or QTextEdit's setHtml method. If the html code is more complicated than just rich text, or you need some html features that QTextDocument doesn't support, then you can use QWebEngineView in Qt WebEngine module.

Ad 1: To recognise a mouse press in an empty area, install an event filter and handle QEvent::MouseButtonPress. Pass the mouse event's point to itemAt() and clear the selection, if it returns nullptr. You can do the same with QEvent::FocusOut, to handle a click outside the list view. Mind that this may not work, in case the list widget is a focus proxy (it isn't by default). Ad 2: The list view is populated programmatically. Just call clearSelection() when this has been done. Ad 3: Read the height after the list widget has been populated. Add the desired height margin and use QWidget::setMinimumHeight().

@peter.thompson You may be able to leverage the following fact into a workaround for your situation. I can state from experience that calling these one after the other ("on the same line", as it were) will trigger the signal you probably want/need to have emitted from the (I believe it is modelUpdated, but don't quote me 😉) beginResetModel(); endResetModel(); (of course they don't literally need to be on one line. I'm just emphasizing that you can call them back-to-back, without having changes to the data happen in between, and the result will be that the model "updates" at this time, as far as other watcher objects are concerned) beginResetModel(); endResetModel(); ... is also fine. I have done this in several applications, and at the time I also looked inside the Qt source code to convince myself that it indeed does do what I intend. My use case was not the case that you describe. Rather, I simply had a "complex", many-nested-if-statement logic for selecting which rows were updated in any given case, and I didn't want to add more complexity trying to meticulously piece together what arguments to pass to dataChanged, so I found I could just do this "hack" at the appropriate point, to signal to the relevant QML to repaint "the whole model" (the visual UI representation thereof, more accurately).

A slightly confusing and complicated way to ask: "How can I create a .h file from a .ui file manually?" The answer is: Use the uic executable as documented here. It's located in the libexec directory of your Qt installation.

@Qreator35 you're missing a Qt version, that install folder should have a folder containing only numbers, representing the installed Qt Version, if installed via the installer/maintenaince tool: [image: 311a2309-9d8f-4465-ab1f-df7700ec55bf.png]

Hello, i'm trying to do something similar, but only with qt_add_qml_module, check out this: https://github.com/Deymoss/MoneyTogether/tree/master/modules/UI and this https://forum.qt.io/topic/162027/correct-way-to-make-qml-modules-qt-6.5-6.9/14 So far, I have not come to a solution to the problem, but I think I will solve it in the next week, thanks a lot to Mike Trahearn, he pushed this question in the qt expert community and said that he has an example that is currently still in progress, so we need to wait and there will be an answer.

Why not use ffmpeg? It is better for rtsp, network streaming etc. https://github.com/denisgottardello/QtFFmpegPlayer

Actually, I expected that one more signal would occur if the readyReadStandardOutput was processing while the process finished. The odd thing was there was a second readyReadStandardOutput signal happening. Although I have checked with the guy doing the actual work, and the second one always returns an empty string when readAllStandardOutput is called.
