Qml chartview segmentation fault

by Mark Zuckerberg
@MatrixSan Thanks, yea from that it looks like QEventLoop is out of scope and cleaned up. Try allocating it on the heap (without worrying bout clean up for now) just to test and see if that goes away. It should. Basically that backtrace is saying it is trying to call activate on a pointer that is invalid (dangling). I recently spent three days on a customer project to figure out why my QML application crashed with a segmentation fault. The crash happened after a long sequence of interactions, which was hard to reproduce. I finally managed to reproduce the crash reliably after going through the same six-step interaction four times.

One of the issues can be related to that Cura could not update the settings from the previous version. To check it you go to the home directory ( on Windows C:\Users\AppData) and remove the cura folder and start Cura again. @Boaschtel said in Segmentation fault when using QML Map and images: MinimalMap.qml: Hi, how can i run it ? Just create a std quick app and copy files? Not sure what to do with MinimalMap.qml: Anyway, the example "Map Viewer" just crashes but only with When I navigate very fast from one index to another far index of on a ListView (using currentIndex property) the qmlviewer crashes. On the example I'm sending I have a feed which each feed entry has an image on the delagate component. Application crashes with Segmentation fault. It happens always when string (url to QML file) is passed to StackView and few other conditions are met. var url = Qt.resolvedUrl("MainPage.qml") pageStack.push(url) I works correctly when an Object is passed: @MatrixSan Thanks, yea from that it looks like QEventLoop is out of scope and cleaned up.

QML, for example, does access registered enumerations through the meta object system. This function was introduced in Qt 5.8. See also Qt's Property System. Q_FLAG () This macro registers a single flags type with the meta-object system. It is typically used in a class definition to declare that values of a given enum can be used as flags and

A theme is a built-in collection of UI style related settings applied to all the visual elements of a chart, such as colors, pens, brushes, and fonts of series, as well as axes, title, and legend. The Qml Oscilloscope example illustrates how to set a theme.

The Qml Oscilloscope example illustrates how to set a theme. You can also select one of the stacked areas for a closer look as a line series by a mouse click (see ChartViewHighlighted.qml). Qt Multimedia is an essential module that provides a rich set of QML types and C++ classes to handle multimedia content. It also provides necessary APIs to access the camera and radio functionality. The included Qt Audio Engine provides types for 3D positional audio playback and content management. I have a QML PySide2 application that has a custom ChartView containing a PieSeries. The application starts and runs as expected. However, the program will occassionally crash when exiting (maybe 50% of the time). This crash has been noted on several versions of Windows and on the latest version of macOS.
