SUMMARY kdialog 20.12.1 STEPS TO REPRODUCE 1. Use chromium browser to upload a file, or kdialog --getopenfilename to open the KFileDialog picker 2. Click Show Preview to see thumbnails. 3. Click OK or Cancel, does not matter which. 4. Open the file picker again. OBSERVED RESULT Notice that the thumbnail previews are not showing up, and "Show Preview" must be clicked again. EXPECTED RESULT It should save the option to show previews. SOFTWARE/OS VERSIONS Linux: Arch Linux 5.10.6-arch1-1 (available in About System) KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION grep -i 'preview' ~/.config/kdeglobals Show Inline Previews=true Show Preview=true These options are set to true. If I disable previews by clicking it twice and then closing the dialog the Inline Previews option changes to false. This tells me that kdialog is using these options but not respecting them.
I can't reproduce this, I've opened kdialog as you mentioned and I can toggle off or on previews and the file changes. kdialog then respects that choice next time it's opened. grep -i 'preview' ~/.config/kdeglobals Show Inline Previews=true
Thank you for looking into this. Strange that the bug is not occurring in your case. I would note that I do see the inline previews switch to true or false depending on which setting I leave the dialog in - but when opening it does not seem to take into account the setting.
