Re: [SailfishDevel] Linux desktop software on Sailfish?

[Marcin Mielniczuk]

IIRC there were some community Fremantle gtk apps, some others using libhildon. 
Tuner was one of them.

Re: [SailfishDevel] Keep an application running without keeping the window open

Do I understand correctly that the dbus daemons run as usual systemd
--user daemons and simply communicate over dbus?

Re: [SailfishDevel] Keep an application running without keeping the window open

[Marcin Mielniczuk]

I'm not sure if that's a good choice when trying to achieve portability.
Usually on desktop you'd rather have a monolithic application with just
minimize to tray.

Any other options?

[SailfishDevel] Keep an application running without keeping the window open

[Marcin Mielniczuk]

Hi,

When creating SFOS applications which should run 24/7 (e.g. IMs) we
would like to achieve similar behavior as the stock applications, e.g.
the stock e-mail client: the sync (*) runs in the background, even
though the application is closed. A window staying open just to make
sure the sync goes on clutters the open app view and makes it more
difficult to manage the open applications.

On a desktop DE one would simply minimize the application to tray.
Alternatively, one could create a daemon which the client app would
communicate with using UNIX sockets, but it greatly increases the
complexity of the application and slows down the development.

What's the easiest way to keep the sync process in the background
without keeping the window open?

Regards,
Marcin

(*) when speaking sync, I mean any kind of waiting for a remote event,
no matter if it's done by idle TCP (which is good) or HTTP polling
(which is not good)

[SailfishDevel] [OBS] What should I do if rpmlint just crashes?

[Marcin Mielniczuk]

Hi,

While trying to build newer boost on the OBS, I encountered the
following problem:

[ 1672s] RPMLINT report:
[ 1672s] ===
[ 1742s] Traceback (most recent call last):
[ 1742s]   File "rpmlint.py", line 371, in 
[ 1742s]   File "rpmlint.py", line 160, in main
[ 1742s]   File "rpmlint.py", line 217, in runChecks

[ 1742s] 22 packages and 0 specfiles checked; 0 errors, 45 warnings.

which makes the whole build fail.

What should I do with it? A search yields almost nothing (the only
result doesn't seem related)

I'm using a _service to fetch the sources:
https://build.merproject.org/package/view_file/home:marmistrz:swiften/boost-opt/_service?expand=1
(for future readers: revision 10)

Re: [SailfishDevel] booster loading wrong libstdc++

I think it would be wise to allow blacklisting a single library from
being boosted or allowing multiple library instances in booster.

Re: [SailfishDevel] Documentation for mlite5

Why do I need CONFIG += link_pkgconfig? It seemed to work with only
PKGCONFIG += mlite5, but maybe I just didn't find the pitfall.


And I didn't have PKGCONFIG += sailfishapp at all in my pro, just CONFIG

[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?

Re: [SailfishDevel] Persistently storing a ListModel

[Marcin Mielniczuk]

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.

[SailfishDevel] Persistently storing a ListModel

[Marcin Mielniczuk]

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?

Could this be result of some firewall or mandatory access control  
(SELinux, AppArmor, ...) on your installation? (Can you SSH to any 
other VirtualBox VM? If you have no other VM, could you install e.g. 
Arch Linux in your VirtualBox, setup port forwarding like it is done 
with build VM and emulator from Sailfish SDK and check if you can SSH 
to it?)

[SailfishDevel] Timeout of MerSDK and the Emulator

[Marcin Mielniczuk]

Hi,

I installed the SailfishOSSDK-Beta-1602-Qt5-linux-64-offline.run on my
Arch Linux. I'm using Virtualbox 5.1, uname -a is: Linux arch
4.4.15-1-lts #1 SMP Mon Jul 11 20:46:47 CEST 2016 x86_64 GNU/Linux

I created a sample project and ran the SailfishOS emulator. Within 30
seconds the emulator window has appeared. Anyway, the SDK reported a
timeout and asked whether I want to try running the emulator again. The
Virtualbox GUI app reported a running VM too.

The same happens for the MerSDK VM.

The log is: ( tried to launch the MerSDK machine too)

 You can also find on the Chinese market smartphones like the Samsung
 Galaxy Golden.
 But of course the best smartphone with a physical keyboard will be the
 one which Jolla will make ;) (if Jolla will do it one day ...)

  Thank you, now I have a better understanding of how it works.

  If you can run Nemo on your device you can just add/replace Jolla

  You will not have possibility to install android apps until

  Still about a Neo900 support, I have an other question :
  
  As far as I understand, basically Sailfish is Mer (Wayland
  version) with
  the Jolla UI, and with an Android kernel and libhybris. So if I
  am able
  to have Nemo running rightly on a N(eo)900 with Wayland, I will
  be able
  to run Sailfish apps ? And if I am able to do it with an Android
  kernel
  and libhybris, I will be able to have it working with the
  possibility to
  install Android apps ?
  
  Best regards

  I'm very interrested by Sailfish OS, however I'm also very
  interrested

  DM3730 1 GHz processor (Cortex-A8 with ARMv7-A instructions,
  mono-core)
  and 1GB of RAM (more here : http://neo900.org/specs). Do you think
  Sailfish will be able to run smoothly on it ? Will you support the
  Neo900 and allowing users to install your OS on it ?

Re: [SailfishDevel] SailfishOS SDK in /opt

[Marcin Mielniczuk]

Well, I should've said it more precisely :) - I open a project created by the 
first alpha. I click the emulator button. It grays out, nothing happens.

 Do you have a project open? The Emulator and SDK launch buttons remain

 Zitat von Mikael Hermansson m...@7b4.se:
 
  That should work, I have it in opt and have no problem.
  
  Looks more like you have an issue with you project file?
  
  check the compile output/message screen if you get qmake errors or
  similar?
  
  also try build-clean all.

 Do you have an idea what was it in your case? I mean the reason why you
 didn't receive mails.

 Try Qt.application.active instead. applicationActive was needed due to
 details about how our X11 stack worked. In a future release,
 applicationActive is deprecated (and aliased to
 Qt.application.active). There were some fixes required to make it
 work, however, so it could be the case that it simply won't work until
 a future SDK update.

[SailfishDevel] Application always active

[Marcin Mielniczuk]

Hello,

I'm trying to utilze ApplicationWindow.applicationActive to set the cover
text. But the onApplicationActiveChanged signal isn't emitted, and the
applicationActive property is always true. (When I used an cover action
logging the applicationActive property, it was printed as true, even though
the app was minimized)

Some of the code;
main.qml:

 import QtQuick 2.1
 import Sailfish.Silica 1.0
 import BigText 1.0
 import pages

 ApplicationWindow
 {
 id: appwin
 initialPage: MainPage { }
 cover: Qt.resolvedUrl(cover/CoverPage.qml)

 Settings {id: settings}
 property string bigTextFontFamily: (settings.fontFamily != ) ?
 settings.fontFamily : Theme.fontFamily
 property string bigTextText

 Component.onDestruction: console.log(quitting)
 onApplicationActiveChanged: console.log(active =  +
 applicationActive)

 }


CoverPage.qml

 import QtQuick 2.0
 import Sailfish.Silica 1.0

 CoverBackground {
 Label {
 id: label
 anchors.centerIn: parent
 text: bigTextText
 }

 CoverActionList {
 id: coverAction

 CoverAction {
 iconSource: image://theme/icon-cover-next
 onTriggered: console.log(appwin.applicationActive)
 }
 }
 }


What am I doing wrong? Or is it a bug?
