Bug ID: 469234
Summary: SensorDataModel: MetaData never update if sensors set
when disabled
Classification: Applications
Product: plasma-systemmonitor
Version: 5.27.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: orblazer.minecraft+...@gmail.com
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
SUMMARY
When we create QML object `SensorDataModel` and we set `sensors` with `enabled`
set to false, the sensors MetaData is never requested so `ready` status is
always "false".
STEPS TO REPRODUCE
1. Create simply applet with :
```
import QtQuick 2.9
import org.kde.ksysguard.sensors 1.0 as Sensors
Item {
Timer {
interval: 1000
running: true
onTriggered: sensorsModel.enabled = true
}
Sensors.SensorDataModel {
id: sensorsModel
enabled: false
sensors: ["cpu/all/usage"]
onDataChanged: (index) => console.log(index, data(index))
}
}
```
2. See the null index and error in log.
OBSERVED RESULT
- `ready` is never true
- `data` is never updated
EXPECTED RESULT
Work as intended.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.27.4
(available in About System)
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8
ADDITIONAL INFORMATION
Currently the only solution i have found is to re assign sensors when i enable
"SensorDataModel". I done this with that code :
```
const sensors = sensorsModel.sensors;
sensorsModel.sensors = [];
sensorsModel.sensors = sensors;
```
