The reason this is happening is because the BottomEdgePage sets a new PageHeader that overrides the default PageHeader of the gallery Template page. The old PageHeader is no longer visible because it has no parent any more, but it still sets/unsets the flickable topMargin.
I will work on fixing this together with the fix for this bug: https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1560458 -- 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/1560419 Title: Header causes wrong flickable.topMargin to be set in BottomEdgePage Status in ubuntu-ui-toolkit package in Ubuntu: Confirmed Bug description: r1886 How to reproduce: 1) Open UITK gallery, it should open in 2 columns mode 2) Go to Bottom Edge page 3) Resize window so that the AdvancedPageLayout switches to 1 column layout 4) Look at the top margin of the Bottom Edge page content Expected outcome: The margin is the same as in 2 columns layout Actual outcome: The margin changes, and a blank space appears at the top, below the header To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1560419/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
