Bug ID: 511339
Summary: Dolphin does not preserve file selection order when
launching Meld
Classification: Applications
Product: dolphin
Version First 24.12.3
Reported In:
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

SUMMARY
File selection order not preserved when launching Meld from Dolphin
STEPS TO REPRODUCE
Open Dolphin and navigate to a folder containing two files you want to compare.
Select the two files by clicking them in a specific order (e.g., click new.txt
first, then old.txt).
Right-click and choose a custom action or service menu entry that launches Meld
with the selected files.
Example of a /usr/share/kio/servicemenus/meld.desktop file used to launch
Meld:
[Desktop Entry]
Actions=meld
Type=Service
MimeType=inode/directory;application/octet-stream;
X-KDE-RequiredNumberOfUrls=2
[Desktop Action meld]
Name=Compare Files with meld
Icon=org.gnome.Meld
Exec=meld %F
OBSERVED RESULT
Meld opens with the same file always appearing in the right panel, regardless
of the order in which the files were selected in Dolphin.
EXPECTED RESULT
Meld should receive the files in the order they were selected in Dolphin, so
the first-clicked file appears in the left panel and the second-clicked file in
the right panel.
SOFTWARE/OS VERSIONS
Windows: N/A
macOS: N/A
Linux/KDE Plasma: Ubuntu 25.04 with KDE Plasma 6.3.4
ADDITIONAL INFORMATION
This issue affects workflows where file comparison order matters (e.g.,
comparing a newer file against an older version). Dolphin appears to pass
selected files to external applications in alphabetical or internal order, not
by selection sequence. This limits the usefulness of tools like Meld when
launched via Dolphin.
