Bug ID: 452842
Summary: create preview of files instantly when the user
scrolls through folders with a lot of files
Product: gwenview
Version: 22.04.0
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: rauchwo...@gmx.net
Target Milestone: ---
SUMMARY
when gwenview is used to show folders with hundreds/thousands of files the time
to create a preview of files can take a long time. If the user scrolls down to
pictures without an existing preview, gwenview should not create previews in a
linear way and should instead prioritize the creation of preview for the
pictures that are currently in "focus"
STEPS TO REPRODUCE
1. open folder with massive amounts of pictures
2. scroll down some pages
3. wait for a long time until the preview of the focused pictures is created
OBSERVED RESULT
wait for a long time until the preview of the focused pictures is created, when
the user scrolls down
EXPECTED RESULT
the preview of the focused pictures is created instantly, when the user scrolls
down
