Hi Filip, sorry for the top-posted reply, but my client is inadequate :) 1. pushExtra() is now an official part of the PageStack API, except that it has been renamed to pushAttached().
Until recently, pushExtra was provided to support a specific use-case, and we hadn't fully considered whether we should expand the API to create a general distinction between stack operations and the location of the visible page. We have now decided not to do this, as it would add complexity to the general use cases for little practical benefit. So pushAttached is the official solution, and has now been documented as such - please use it in your applications where appropriate. The functionality pushAttached provides is to allow a page to be added to the stack, not as an independent element but as an additional page attached to the page which is currently the stack top. The 'attached' page cannot be popped independently - it will only be removed when the primary page is removed. While it is on the stack, the user can freely navigate between the primary and attached page(s), without causing anything to be removed from the stack. It is therefore appropriate for displaying additional or contextual information, which is nice to have handy, but not cluttering the interface. 2. & 3. Thanks for the report, I will ensure this is fixed. As you have noticed, if anything goes wrong with the PageStack, then it is time to restart your application, as it does not recover well :) Also, thanks for trying the SDK, and finding the spelling issues! Thanks, Matt ________________________________________ From: devel-boun...@lists.sailfishos.org [devel-boun...@lists.sailfishos.org] on behalf of Filip Kłębczyk [fklebc...@gmail.com] Sent: Sunday, March 03, 2013 12:08 AM To: devel@lists.sailfishos.org Subject: [SailfishDevel] Sailfish pageStack, web-like forward/back browsing, pushExtra() Hello all, I've encountered few interesting things when playing with Sailfish SDK which I would like to share with you and look for some answers here. 1. In the Sailfish Silica documentation page about QML PageStack there is only one of the push methods described - push(). It's behavior is simple it pushes page to stack and switches to it. In gallery of Silica components you can see that there is also another way to push pages on stack - that is through pushExtra(). What's interesting in the pushExtra() method? It allows you to achieve a web browser-like forward/back navigation through pages (as far as I remember thp was interested in such functionality yesterday on #sailfishos). Anyway I wonder why there is nothing about pushExtra() in the offical documentation? Do we developers are not supposed to use it or is it planned to be official for the future releases of Sailfish? 2. Regarding pushExtra() I noticed that when there is only initial page (so one page on the stack) then even if you use pushExtra() you cannot easily access to the next page (through swiping/flicking from left to right) like it is possible, when there are already more pages on the stack. Is there a solution for this problem? 3. I also found an interesting bug which you can easily achieve by using push() then few times pushExtra() and then push(). It makes a a real mess to the stack. To let you understand all the points better here is a video that shows above issues (yay! everyone loves videos!) http://www.youtube.com/watch?v=UFfRy5zd2O8 Last but not least I would like to thank Jolla for releasing great alpha SDK and our amazing community for what it is doing with it since it's release. Best regards, Filip PS. Some spelling errors I've found reading documentation: https://sailfishos.org/sailfish-silica/qml-sailfishsilica-applicationwindow.html Hierchical -> Hierarchical provdes -> provides PS2. It would be nice (at least for me) if the names of methods in documentation would somehow differ from their description (bold or some typewriter font?). _______________________________________________ SailfishOS.org Devel mailing list _______________________________________________ SailfishOS.org Devel mailing list
