Hi,

I mentioned it on a later message, but everything seems to work now. Thanks
everyone!

Aihe: Re: [SailfishDevel] Problems with the emulator (I think)

  Hi Lauri,

you don't mention which SDK installer you have used. That would be vital
information in troubleshooting this and any future problems :-)

None of the problems below seem to concern the SDK emulator. I believe
these are build time problems?

  Hi all,



First time on this list, so sorry if this is an old problem but:

When I created my new project on SailfishOS IDE the main.cpp file complains
that:

#include 
”No such file or directory”


The sailfishapp.h is part of the libsailfishapp-devel package, which is
preinstalled in the latest "1310" installer targets released last month. If
you have an older SDK, then this package might not yet be available.

If you are using the latest SDK, then with this information at hand, I
cannot fathom why it would not be found.

When you say "When I created my new project", how did you create it?


And whenever I try to add a package to my sdk it says the following (as an
example):

Operation Progress

 finished: installing package
jolla-sailfish-core - exited with status 0



Loading repository data...

Reading installed packages...

'jolla-sailfish-core' not found in package names. Trying capabilities.

No provider of 'jolla-sailfish-core' found.

Synchronising target to host

cannot delete non-empty directory: usr/bin

Sync completed


This looks perfectly fine, although unnecessarily cryptic.

There is in fact no package called "jolla-sailfish-core". The
jolla-sailfish-core is a pattern, not a package. A pattern is metadata
describing a collection of packages. Unfortunately the web management view
does not understand that and shows it as a normal package and tries to
install it as a normal package.

What's happening in the background is that the web management calls zypper
install for the "package", but since there's no such package, it does
nothing and unnecessarily syncs the results between the target and the host.

If you try to add some real package, then it should report something
different.

Best regards,

 Juha



Thank you J

I was wondering exactly the same as Gabriel and Andrey's code solved my
problem.

Thanks a lot, guys!!!

Re: [SailfishDevel] ListModel sorting in QML

[Artem Marchenko]

I had similar situation in the past.

Data was coming from web, but I needed to rearrange it for QML lists to
work.
What I found useful and working was to just generate a new model in
JavaScript (based on empty ListModel if I recall correctly). I had only a
couple of dozens of data and it was changing once or twice during app use
sessions. So creating a fresh model from scratch was not a problem at all.

Cheers,
Artem.

Of course I would like Item6 to be set between Item2 and Item3.

How is possible to do that in QML? I would like to avoid manually iterating on

[SailfishDevel] ListModel sorting in QML

[Tigre-Bleu]

Hi,

I have a ListView which loads a model from JSON with JSONListModel. The model 
contains items and category ids, but is not sorted by category.

What I wand to do is to display the items sorted by categories in the ListView. 
I have put a section.property in the ListView but it is working only half as 
expected because it is not sorting the model.

For instance, if my model content is:

Item1 - Category1
Item2 - Category1
Item3 - Category2
Item4 - Category3
Item5 - Category3
Item6 - Category1

Then my ListView will display:

Category1
  Item1
  Item2
Category2
  Item3
Category3
  Item4
  Item5
Category1
  Item6

Of course I would like Item6 to be set between Item2 and Item3.

How is possible to do that in QML? I would like to avoid manually iterating on 
all the items to re-order.

Thanks,

Re: [SailfishDevel] Problems with the emulator (I think)

[Alessandro Portale]

Perhaps your project configuration still has some old SDK paths in it. Two
different ways of fixing this:

- Delete and Re-add the SailfishOS kit(s) in the "Project" mode in Qt
Creator
- Manually delete the .user file from you project folder and open
the Project in Qt Creator

Cheers,
Alessandro
