[Bug 1493040] Re: PageHeadSections: changes selection when adding/removing items

 

As requested in this bug https://bugs.launchpad.net/ubuntu-rtm/+source
/ubuntu-ui-toolkit/+bug/1513933 I made these changes:
https://code.launchpad.net/~tpeeters/ubuntu-ui-toolkit/pageHead-
sectionsIndex/+merge/279834 to reset the sectionIndex to -1 when the
model changes. The motivation is that the UITK cannot tell which section
should be selected after the model changes. The app can tell however, so
it can update the selectionIndex after changing the model.

** Changed in: ubuntu-ui-toolkit (Ubuntu)

Title:
  PageHeadSections: changes selection when adding/removing items

Status in ubuntu-ui-toolkit package in Ubuntu:
  Won't Fix

Bug description:
  When adding/removing an item from the model, the item selected by the
  PageHeadSections changes. Selecting the next item along when removing
  an item before the selection, and the previous item when adding an
  item before the selection.

  Note that this behaviour works correctly in the Picker component
  (except for bug #1344883). Basically, the element should pay attention
  to changes in the model and update it's selectedIndex appropriately in
  order to continue selecting the same element after updates.

  A minimal example is attached to demonstrate the problem.
