Bug ID: 501773
Summary: Selecting items is slow and laggy
Classification: Applications
Product: digikam
Version: 8.5.0
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: digikam-bugs-n...@kde.org
Reporter: k...@kenrushia.com
Target Milestone: ---
SUMMARY
Selecting items from Icon or Table view becomes slower when more items are in
the view. This appears to be caused by the loop in
DigikamApp::slotImageSelected that totals the item sizes.
STEPS TO REPRODUCE
1. Open an Icon view with 10000 images
2. Add some images to the selection
3.
OBSERVED RESULT
Each time the selection changes, the GUI lags or locks up
EXPECTED RESULT
No lag please

ADDITIONAL INFORMATION
Seems like this loop should be tied to refresh of the view instead of the
selection. Also, if the status bar or properties pane aren't displayed then
there isn't a reason to do the calculation.
