If you use the HolidayRegionSelector with listSelectionMode set to SingleSelection and enableRegionUseFlags set to false then you can still select more than region. Reproducible: Always Steps to Reproduce: 1. Start Qt Designer 2. Create form with KHolidays::HolidayRegionSelector 3. Set listSelectionMode to SingleSelection and enableRegionUseFlags to false 4. Preview Form Actual Results: 1. You can select more than region by ticking the checkboxes Expected Results: 1. Ticking a second checkbox or should untick any other checkbox. I did try and find examples where other code used HolidayRegionSelector used SingleSelection but couldn't. I expected the behaviour to be similar to that of QAbstractItemView::SingleSelection
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kdepim (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
