Current DiskUsage RTL
DESCRIPTION
When using an RTL interface (such as Arabic), the Disk Usage widget displays
inverted progress charts.
Instead of filling from right-to-left starting at 0%, the progress bar stays
anchored on the left side (at x: 0) while its width shrinks/expands using the
mirrored value. This makes a 70% full drive look like it only has 30% space
used, and vice versa.
STEPS TO REPRODUCE
To isolate and reproduce the issue without changing your entire desktop layout,
run the Disk Usage plasmoid standalone using plasmoidviewer forced into an
Arabic (RTL) locale:
1. Install the Plasma SDK (if not already installed) to get plasmoidviewer.
2. Run the following command in your terminal to launch the applet in Arabic:
LANG=ar_EG.UTF-8 LANGUAGE=ar LC_ALL=ar_EG.UTF-8 plasmoidviewer -a
org.kde.plasma.systemmonitor.diskusage
OBSERVED RESULT
Observe the progress bars: they fill from left to right, but their visual width
is inverted relative to the actual percentage values (e.g., a higher percentage
yields a smaller visual bar). See the screenshot Current_DiskUsage_RTL.png
EXPECTED RESULT
In an RTL layout, progress bars should start on the right side and visually
fill towards the left as the value increases. See screenshot:
Correct_DiskUsage_in_RTL.png
Possible fix:
The issue lies in
/usr/share/ksysguard/sensorfaces/org.kde.ksysguard.horizontalbars/contents/ui/Bar.qml
I modified the contentItem property from:
contentItem: Item {
Rectangle {
width: bar.visualPosition * parent.width
height: parent.height
color: bar.color
radius: height / 2
}
}
to:
contentItem: Item {
Rectangle {
width: bar.position * parent.width
x: bar.mirrored ? parent.width - width : 0
height: parent.height
color: bar.color
radius: height / 2
}
The AI explain this as following:
Currently, the inner progress indicator `Rectangle` relies on
`bar.visualPosition` to determine width, but it is missing a dynamic `x`
coordinate mapping for mirrored layouts.
Using `bar.position` (which is direction-agnostic) combined with a conditional
`x` offset fixes the alignment and fill direction perfectly.
