[MeeGo-touch-dev] Soft API Break: MApplicationPage enterDisplayEvent(), createContent()

[Dominik Kapusta]

Hello,

We found a way to deal with createContent() behind the scenes[1], so calling MApplicationPage::enterDisplayEvent() in inherited classes won't be needed starting from libmeegotouch 0.20.35 (the change affected only 0.20.34.2).

Thanks,
Dominik

Hello,

commit 434962fec0fc0e722f730c275705d75fa17570da in libmeegotouch[1] introduces a behavioral change in MApplicationPage, related to createContent() and enterDisplayEvent().

>From now on, MApplicationPage::createContent() is called from within MApplicationPage::enterDisplayEvent(). It means that if your inherit MApplicationPage and reimplement enterDisplayEvent(), you should call the base class implementation at the beginning of your method. This way you ensure invoking createContent() and having your content in place.

Failing to do so may result in crashes when accessing components created in createContent() (as that method would never get called).


Regards,
Dominik
