SUMMARY In the quick settings page, press with the left mouse somewhere in the gray area in order to unfocus the search field in the upper left corner. Then press Ctrl + F. OBSERVED RESULT Search field is focused, but one cannot type into it. EXPECTED RESULT Search field is focused and typing into it is possible. Is this maybe even a Qt bug? If so, do you know if there's already a report? SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20210613 KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 Graphics Platform: X11 same on current Fedora 34.
Created attachment 139344 [details] Screen recording 1) Click into the gray area and pressed Ctrl + F: Search field focused but typing into it does not work. 2) Click into the white pane: Search field keeps being focused but typing into it now does work.
Weird, confirmed. Reproduces on all QML-based KCMs, not just the landing page: the search field visually gains focus, but typing does nothing.
I was going to file a separate bug about the search field not getting focused when the sidebar opens a subcategory of settings pages (e.g. "Appearance") and Ctrl+F doesn't focus the search field unless it's already visible. But looking closer, it seems as if this is probably the same issue. Steps that work (almost) as expected: 1. Click "Appearance" and the "Global Theme" view opens on the right. 2. Make sure your window is narrow enough so you only see one sidebar column on the left (showing the "Appearance" tree of pages) and "Global Theme" on the right. 3. Type Ctrl+F. Nothing *seems* to happen, however the search field focuses clandestinely. 4. Type any letters. The sidebar slides back to the search field and finds pages. Steps that do nothing: 1. Click "Appearance" and the "Global Theme" view opens on the right. 2. Make sure your window is narrow enough so you only see one sidebar column on the left (showing the "Appearance" tree of pages) and "Global Theme" on the right. 3. Click into the white space on the right. 4. Type Ctrl+F. Nothing happens. 5. Type any letters. Nothing continues to happen. Both the original report and my experiment make it seem as if the search field has focus within the sidebar view - if the sidebar has focus, then typing in the search field will also work - but clicking into the main view of the opened KCM transfers focus away from the sidebar and Ctrl+F doesn't bring it back. I'm not versed enough in Qt/QML to hypothesize why the search field would grab focus for the field within the sidebar but not for the sidebar itself. That's where I'd start looking, though.

Ctrl+F still doesn't work on up-to-date KDE Neon user edition: The search field gains focus (carret is blinking) but you can't enter text.
