This is not a bug in APL or header, but in the gallery. The APL currently does nothing with the PageHeader when changing the layout, the apps need to deal with that. The gallery does that by setting and unsetting the PageHeader.flickable property, but that does not automatically reset PageHeader.exposed when the flickable is set or unset.
This can be a feature that we add to the APL. We would need some UX input for that to describe what should happen exactly when changing the layout. That would be a separate bug though. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1556860 Title: Blank left panel header in gallery after resizing AdaptivePageLayout from two panels to one and back Status in ubuntu-ui-toolkit package in Ubuntu: In Progress Bug description: UITK r1888 Environment: Windowed mode, Vivid+OverlayPPA Steps to reproduce: 1) Launch UI Toolkit Gallery 2) Scroll left panel until the header animates out of screen 3) Resize window so that only the left panel is shown 4) Resize window until it shows both left and right panels Expected Outcome: The Header comes back into view Actual Outcome: Header doesn't show, and its place is taken by a blank box.
