QtCreator errors with QtGraphs QML

[SGaist]

Are you trying to use both Qt Graphs and Qt Charts at the same time ?

[Tobias83]

@SGaist If I remove all the QtCharts promts in CMakeLists.txt and Main.qml, the error remains.

[SGaist]

Did you nuke the build folder after these changes to ensure you start from a clean state ?

[Tobias83]

@SGaist I moved the build directory:

mv build-HardCore-Desktop-Debug/ build-HardCore-Desktop-Debug_old/

Than I executed cmake file again, but I can't build the project and the project is not structered anymore. There is only a file list at the left site. The error in German language is:
:-1: Fehler: CMake-Konfiguration "Debug wurde nicht gefunden. Verfügbare Konfigurationen: "".
Stellen Sie sicher, dass der Wert der CMAKE_BUILD_TYPE-Variable derselbe wie der des "Build-Typ"-Felds ist.

... cmake configuration Debug was not found. Ensure that the variable value CMAKE_BUILD_TYPE is the same as that of the Build Type area.

@Tobias83 Did you try to build in release mode?

[Tobias83]

@jsulm In release mode, there is also the error unknown component for the QtGraphs prompts.

[SGaist]

Even if it was already done once:

• Exit Qt Creator
• Delete the CMakeLists.txt.user file from your sources
• Nuke all build folders
• Start Qt Creator and reconfigure your project

[Tobias83]

@SGaist OK, I did so and there is no change: unknown component )-:

[SGaist]

Since you wrote that the example is building successfully, what about copying it and the gradually replace its content with the one from your project ?

[Tobias83]

@SGaist OK, I coppied the main.qml file from the hellographs example to my project. And the GraphsView prompt was recognized. I found out, what the problem with my Main.qml was. I had to change the import commands:
instead of

import QtGraphs 2.12

change to

import QtGraphs

helped (-:

Thank you very much!!!

But, I have still a question: How can I use the XYModelMapper? Is there a good example? The usage differs to QtCharts, specially xSection : qsizetype ...
