While looking at https://bugs.kde.org/show_bug.cgi?id=494557 I observed that there is no way to set tab order in UI file (with and without Qt Designer) for KNewPasswordWidget. STEPS TO REPRODUCE 1. Create a form with a few widgets such as check boxes, line edits... 2. Insert KNewPasswordWidget in the middle. 3. Set tab order. OBSERVED RESULT No way to set tab order on password entry fields. EXPECTED RESULT We should be able to set tab order for password fields too.
