Re: Heads up! When using AdaptivePageLayout, make sure your Page has a PageHeader.

  Thread Previous • Date Previous • • Thread Next
I agree on this. Isn't it the purpuse of using frameworks/UI toolkit versions? I think this isn't a good practice. This has happended quite frequently. You can't assume that all developers are following this list. In the end the consumers are the one greatly impacted by this. They'll get broken apps from the store. Imagine Google doing something like this. Play Store will surely have millions of apps bot working. That could be a riot. Hopefully we can think of a better way pushing this kind of changes.

Hi Zsombor,

thanks for your reply.

I'd then like to request a better policy for such changes.
When I asked about click frameworks some time ago, I was told that they are meant to keep apps from breaking, each framework should be one fixed environment the app is targeting. But it looks like that's not true. I probably just didn't understand that correctly.
But if it's not the framework versions, then at least the UI Toolkit version should be reliable IMO. As far as I know, UUITK 1.3 was released as a stable release, wasn't it? At least it's the current recommended release. Apps that target a specific UITK release should not just break over time until the release is officially announced as deprecated. At least that's my understanding of releases and version numbers :) I really don't like being forced to update my apps before I'm ready with my next release at least not because of changes like this.
Also, I'm not following this mailing list actively. If there haven't been a message in the Ubuntu Apps telegram group, I would not even have realized this thing. And that doesn't mean I don't care. I love Ubuntu and the phone, that's why I'm writing apps for it! But I don't have unlimited time to do so. It's all my free time I'm spending here. 

Have a nice evening everyone,
Tim

Hello Tim,
As we are not making any new component, and we are targeting this work to happen with 1.3 UI Toolkit, apps made prior to 15.04.5 (or wherever this change will land) will stop working with pages using old header configuration setup. So if you have apps in the store which uses APL with old page header configurations, please update those. 

Cheers,
Zsombor

    Hey Tim,

    I was wondering whether this change does affect all frameworks?

    For example, will an app using the APL and targeting a prior
    15.04.X framework release break because of this change or will
    only 15.04.5 apps be affected?

    Thanks for your reply!

    All the best
    Tim

    Hello all,

    As you probably know, some time ago we introduced the new
    PageHeader component (see
    https://developer.ubuntu.com/en/blog/2016/02/24/pageheader-tutorial/
    ). An instance of PageHeader can be assigned to Page.header to
    define the header of a Page, and if no Page.header is specified,
    there is an automatic fallback to the old header.

    In AdaptivePageLayout (APL), there is also a fallback header in
    each column, but that complicates the APL implementation, it is
    not fully covered by tests, and does not support all the features
    of the new PageHeader, so we will drop support for that soon. We
    need to do this before we move the APL implementation to C++ (the
    API will be the same, so no more changes in app code will be
    needed for that, but the APL will be much faster), so please
update your apps now if you are using APL but not the new PageHeader. 

    We may update the deprecated APL column-header fallback to show a
    red border before we remove it, as a final warning. The progress
    on the removal can be followed here:
https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1583587 

    Comments/suggestions/discussion can be added to the bug report,
    or as a reply to this e-mail.

    Best regards,
    Tim.
