QtCreator errors with QtGraphs QML

SGaist

Hi,

Do you mean you have errors shown from the code model or is your code not working ?

Tobias83

@SGaist The QtCreator says "unknown component". And the runtime error is
QQmlApplicationEngine failed to load component
qrc:/qt_qml/Main.qml:53:13: LineSeries is not a type

SGaist

Can you share a minimal compilable example that shows this ?

Tobias83

@SGaist If I can say this: I think its not a problem with my code. I think there is some software package for QtGraphs missing. In comparism with QtCharts, there is no

libQt6GraphsQml6 -> /usr/lib64/
qt6-graphsqml-devel -> /usr/include/qt6/QtGraphsQml/

When I tried to use QtCharts before, the remaining prompts were also not found by QtCreator, before I installed the corresponding devel packages from the repo ...

@Tobias83 said in QtCreator errors with QtGraphs QML:

LineSeries

do you have
import QtCharts 2.8
in Main.qml?

SGaist

@Tobias83 I just realized you have 6.7. Qt Graphs went out of tech preview with 6.8.

Tobias83

@JoeCFD I have

import QtGraphs 2.12

Graphs went out of tech preview with 6.8

What does that mean?

On my Computer I have libQt6Core6 6.8.2-3.2. I thought the libs are downward compatible. Should I change

find_package(Qt6 6.7 REQUIRED COMPONENTS Qml Core Quick Graphs)

With changing in

find_package(Qt6 6.8 REQUIRED COMPONENTS Qml Core Quick Graphs)

there is no change.

SGaist

How did you install Qt ?
Which packages do you have ?

Tobias83

@SGaist I think its not up to Qt, because QtCharts worked for me. But maybe there is a devel package for qml needed as I wrote ...
