Re: [SailfishDevel] ListView with SectionDelegate (Strange Behaviour)
Hi Gabriel
Thank you for taking the time to reproduce this issue. It is
reassuring to know that based on the admittedly slim evidence of this
issue alone I am not going completely mad!
I agree that the 2 issues sound related (I will have a poke around
with your code later today).
Based on the assumption that this is probably a Qt issue rather than a
Sailfish issue I was about to open an issue on the Qt Bug tracker.
Then standing on the platform waiting for my train to arrive I
thought: How difficult could it be to fire up my Qt5.2 installation
and create a Desktop version of this project to reproduce this issue?
By the time the train pulled in I had my first ever Qt Desktop project
running! I had expected to see the same sections bug, but unexpectedly
I got the expected behaviour! i.e on Qt 5.2.0 desktop I cannot
reproduce this bug.
My next thought was: Maybe this is still a Qt problem, but has been
fixed in Qt 5.2.0?
Luckily I have an old Qt 5.0.0 installation lurking on my laptop. So I
added a Qt version and kit for that, and launched the project as
Qt5.0.0.
Again no Section header bug.
Then I turned to Android with Qt 5.2.0, and once again got expected
behaviour (no bug).
So to cut a long story short, this behaviour appears to be limited to
Sailfish (or the particular Qt version used by Sailfish)
I can reproduce it on the Emulator and real Jolla Device.
I cannot reproduce it on Harmattan Qt 4.7.4 (from which I am porting the code)
I cannot reproduce it on Qt Desktop (5.0.0 and 5.2.0)
I cannot reproduce it on Android Qt 5.2.0 (Emulator and Galaxy Note 3
with KitKat).

Zitat von Gabriel Böhme m.gabrielboe...@googlemail.com:
Hi Chris,
I can reproduce this behavior with the code you posted and it seems to
be a bug.
I have encountered some days ago also a problem with section handling.
If you are appending a new Item to the list, while you use FullString
section headers, it's creating a new section, even if it is already
there. The expected behavior should be, that the new item is sorted
under the right section. Especially in my intended use case, it's a
problem because I want to fetch some data from an online source and sort
it in different sections. But how to do that, without appending? Insert
is also not possible at all, because it's varying always. Even if the
model is set after, appending (again) - it's not working. Also a code
example added at the bottom (just modified your code). The new
person/item with name Tom should be displayed in Boss section, but the
ListView creates another Boss section at the end of the list.
Maybe both are relating to each other?
Thank you very much.
Gabriel.

[SailfishDevel] Different behavior when starting application from QtCreator or Launcher
Hello everybody, maybe someone may shed some light on this odd behavior: I have implemented an active cover in my train timetable application, where the action is enabled when a certain property in a C++ object (a string) has a length different from zero. This property is set by the application when loading data from a station. The odd thing is that this works correctly if I launch the application from qtcreator or fingerterm, but does not when starting it from the launcher. The only thing that may be different is that the application is invoked differently... Maybe it would help me to understand how the laucher invoker works... Can anybody give me some pointer on how it works?

Can anybody give me some pointer on how it works? Hi Luciano, the way QtCreator launches an application is afaik not entirely correct and will be addressed in a future SDK update. To see how the application is lauched when it's started from the homescreen icon, use fingerterm and find your application in the output of 'ps faxw'. If you then start your application from fingerterm as you see it with ps command.. for example: $ invoker --type=silica-qt5 --single-instance /usr/bin/yourapplication The invoker parameters depend on what you have in your .desktop file, which is not used when you start it from QtCreator.

Re: [SailfishDevel] How to flick horizontally and vertically inoneview?
Hi Tobi, maybe a PathView allows you to do what you want. Should be possible to tune it to work like the Jolla calendar app. But it's a good idea to look in the official Jolla files, as well. Maybe there is a much better solution. :) Gabriel. 2014-01-30 sailfishmail sailfishm...@denden.pw Hi, You can have a peek at the calendar qml files in /usr/share/jolla-calendar/ Hope you find some hints there, Br, Asser Tobi D. kirjoitti Thu Jan 30 2014 00:53:08 GMT+0200 (EET): Hi there, I've got another question on how to develop apps for SailfishOS. Please have a look at Jolla Calendar app. There you can flick horizontally between months and you can flick down pulley menu, also from the month part on top of the view. If there are many events in a day, the whole view is vertically scrollable. I want to implement a similar behavior in my app. Content of the view may be scrollable vertically and there shall be a pulley menu. By pushing left and right, the content shall flick to the content of the next respective previous week. I wonder how this works. I tried several things, but I don't know which components to combine to get this behavior. One possible solution is to use push buttons to go to previous/next week, but that's not very SailfishOS like. Maybe you can give me a clue. Or is it possible to have a look at the source code of Jolla Calendar app? Best regards, Tobi ___ SailfishOS.org Devel mailing list ___ SailfishOS.org Devel mailing list
[SailfishDevel] Handling incoming call
Hello all I'm looking for way to observe and hangup incoming calls for my blacklist app. I have found that it might be possible with telepathy but haven't found any more information. Is there any documentation about this or is there other ways to do it. ___ SailfishOS.org Devel mailing list
Re: [SailfishDevel] ListView with SectionDelegate (Strange Behaviour)
Sali Norbert thanks for your confirmation. I have not filed a bug report with the Qt-Project, as my tests on Desktop, Android etc indicate that this is not a general Qt 5.x bug, but a Sailfish specific one. (Despite my expectations, I got expected behaviour on those platforms). My understanding is that this is currently the best place to report Sailfish development bugs. If there is a more appropriate place, then I will gladly report it there.

For the items initially displayed this works well, with the section headers exactly where I would expect them[...] But as I flick up, I then a section header between each item (e.g between Gargantua and Gilbert). I can also confirm that behaviour. In your example and also in an app I'm coding myself. Did you already file a bug or are you still investigating?
