QML and Qt Quick

An expedient solution is to wrap the asynchronous behavior in a customized C++ QObject, initiate the call through a property or Q_INVOKABLE, and later return the result through a property or signal.

@AndyBrice said in Qt Graphs lacking functionalities - Axes range: quickwidgetgraphs doesn't work, nothing happens when you click on the buttons: The *.pro file is broken in Qt 6.10.0 (it's fixed for the next releases). Load the CMakeLists.txt and it will work. I also suggest downloading the latest version of the example (it's not released yet so get it via git): https://github.com/qt/qtgraphs/tree/dev/examples/graphs/2d/quickwidgetgraphs This shows you how to use Qt Graphs without writing any QML code.

Adding your component .qml file to qml.qrc file should do the trick.

QSqlTableModel + TableView sounds like what you need

@IamSumit said in Passwordchar property of TextInput as Unicode not supporting in QNX 7.1: passwordCharacter: qsTr("\u2217") Is translating really the desired goal here? It's an unlikely but possible source of the problem. Does the character in question have a glyph in the font being used by the QNX system, eg can it be displayed via a Text{}?

Hello, do you find the solution? I'm also using the VideoOutput to display my frames and it also becomes blurry. I tried your suggestion: VideoOutput { ... layer.enabled: true smooth: false } But this still doesn't help

Apparently I was running 6.9.3. Code works in 6.10. Thank you!

As a workaround it should be possible to use a built-in #Sphere mesh. You can see more info about the dimensionality here: https://doc.qt.io/qt-6/qml-qtquick3d-model.html#mesh-format-and-built-in-primitives

@Bob64 @Bob64 said in TableView: the highlight of the selected row is displayed only after scrolling: color: { console.log("Color changing - selected = ", selected); selected ? "#F1F8E0" : "#ffffff" } It's working fine! Also, to select the entire line, I had to replace:: @woodpecker said in TableView: the highlight of the selected row is displayed only after scrolling: tableView.selectionModel.select(tableView.index(row, 0), ItemSelectionModel.Select); with: tableView.selectionModel.select(tableView.index(row, 0), ItemSelectionModel.Select **| ItemSelectionModel.Rows**); .

Someone pointed me to the TableViewDelegate; I switched to that since it comes with the functionality that I need.

Hi, What kind of example do you have in mind ? How to use OpenCV ? How to grab an image with Qt and apply OpenCV operations on it ?

im using Qt Charts , you think i can find a way with Qt Graphs ?

Thanks for your answer. In meanwhile I was able to solve this problem. I think it was related to the singleton. The QtObject blub was in a singleton-qml-module. Now I moved this QtObject to the main-qml-module. Now the copy is much faster and it does not get slower.

@Bob64 Thanks for the detailed reply!

Why dont you use https://doc.qt.io/qt-6/qml-qtquick-vectorimage-vectorimage.html

@jsulm That makes sense! Also, you are damn fast, thank you for reviewing my message!
