SUMMARY In details view, if a highlighted item is directly behind (obstructed by) the header, right-clicking in the header within the obstructed highlight rect will trigger the item's context-menu and not the header's. STEPS TO REPRODUCE 1. Toggle details view and navigate to some location that allows scrolling. 2. Highlight any item and scroll the panel such that the highlighted item gets covered by the header. 3. Right click on the header at the covered item's *highlighted* rectangular region. Note that this only occurs in the highlight rect, and not anywhere in the row. OBSERVED RESULT The context-menu of the selected item gets triggered. EXPECTED RESULT The header's role configuration menu (the menu to show/hide columns, etc.) should be triggered. This is reproducible in both 21.08.2 and 21.08.0, I have not tested this on any other version yet. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Testing a bit more, it's not necessary to highlight anything. The bug occurs if you simply right-click on the header in a location that needs scrolling. Essentially, file item's text (and not the entire row) rect hit check was done before the header's so the click events gets swallowed.
This issue is most obvious if https://invent.kde.org/system/dolphin/-/merge_requests/278 gets merged, I've added a fix in that MR for now.
