[SailfishDevel] Updating gcc?

[Marcin Mielniczuk]

Current gcc in Mer is 4.8, which is 2 years old. Current releases (5.4,
6.1) have full support for C++14, 4.8's support for C++11 is only
experimental.

C++11 brought many important changes such as constexprs or simply really
useful ones (auto types). It'd be great to have them in Mer.

Are there any plans for updating gcc in Mer?

[SailfishDevel] Documentation for mlite5

[Marcin Mielniczuk]

Is there any online documentation regarding mlite5? I'm not really sure
how I should use it in my project, whether I should include 
or . What is the preferred way of achieving decent
linking? I found some examples using PKGCONFIG - is it the good way?

There should be at least a minimal example in the README, the rest can
be derived from the doxygen comments. But, since the doxygen comments
are already there, why not put the docs online?

Re: [SailfishDevel] Persistently storing a ListModel

[Andrey Kozhevnikov]

pointer is an address to memory, its pontless to save, you should save 
data.

dconf can be accessed using MGconfItem from mlite5 library.

Thanks a lot!

So I'm trying to store a pointer to ListModel and ConfigurationValue
drops this silently because it's an invalid value, doesn't it?

What is the standard way in Sailfish to access DConf from C++? I think
about reimplementing the model as a subclass of QAbstractListModel 
anyway.

 to store model data you should recursively convert model data to
 array, and vise versa.

 Тема: [SailfishDevel] Persistently storing a ListModel


 Hi,

 I'm currently using org.nemomobile.configuration to store the
 application settings. Now it came out it'd be beneficial to store a
 ListModel between runs (if a user wants it).

 I tried the naive approach:

 property ListModel myModel: modelStorage.value

 ConfigurationValue {
 id: modelStorage
 key: Constants.modelStorageKey
 defaultValue: ListModel {}
 }

 But no dconf key seems to be generated after I populate the model.

 What is my best bet in this case? Is this the expected behavior or 
have

 I done something wrong on my side?
