Hi All

I have just installed the April SDK update, and have opened an  
existing app, and am trying to deploy to my Jolla.


The app worked with the previous SDK release, and is already installed  
on the phone.


If I deploy as Deploy by copying Binaries then thinks work as  
expected, and the app successfully deploys and starts on the phone.


If I deploy as Deploy as RPM Package, then I get the error below in  
QtCreator, and a white screen of death on the phone.

Re: [SailfishDevel] After April SDK Update Existing App fails on RPM deploy to Jolla Device: Possible rights problem


Hi Andrey

Thanks for the fast answer

Given that we are talking about cross-platform development -  
developing on one and deploying to another I am not sure that is  
always possible. What if my development host was Windows?


And as a developer I want to worry about writing code, not all the  
arcane rights that all the files need to work when deployed


In fact my main development host is OSX which has unix like  
permissions, the same as Sailfish. Having a look at the files on my  
host, it looks like the files are now deployed with the original  
(strange mix of) rights from my host.


However in previous SDK releases this was not an issue, As far as I  
can see the SDK took care of permissions.


In the meantime I will chmod the files on the host and see if that helps...

Cheers

Chris

IMHO you should manage file permissions yourself before deploying?

I am not sure why the files on my host have such wildly different  
permissions. This probably reflects the different ages / sources of  
the files. Until now the permissions set on the host was not an issue  
I had to think about.


I have now done a chmod 777 *.js


That got me a little further, it next complained about missing qml  
files, so we have a similar issue with the permissions of .qml files.


Having gone through all my qml file in the project on my host with  
chmod 755 *.qml the project now deploys successfully to the device.


So it looks like, that (at least on OSX) the permissions of files on  
the host are important and need to be set correctly as expected on the  
end device. Something for the known issues page?

Hi Chris,

I've changed the way the shared directories are mounted to the  
virtual machine. This might be caused by that. Previously the shared  
folders were mounted with 777 rights and all files were shown as  
read/write/exec for all inside the virtual  machine. I've changed it  
so that the rights are as they are on your host filesystem.


But there's really no reason for those two files to have only root  
access and the others have more access unless there's some root  
cause with your source files.


There's no code anywhere in the SDK that checks if a file is named  
'landed.js' and modifies its access rights :-)


What are the source files' permissions in your Mac's filesystem when  
you list them?


Best regards,
 Juha

Re: [SailfishDevel] After April SDK Update Existing App fails on RPM deploy to Jolla Device: Possible rights problem


Hi Mohammed

thanks

The varied permission on the qml / js files on my host probably  
reflect that the project originated in pre-sailfish days, and thus the  
files have come from various sources / versions of Qt Creator / edited  
with different text editors etc. since then.


I have now set all qml and js files in the project on my development  
host to chmod 644

e.g
-rw-r--r--   1 christopherlamb  staff   7,7K 24 Feb 17:20  
InitialCharacterPicker.qml


Are these the correct permissions? It is how a new demo project sets  
the permissions.


Chris

Zitat von Mohammed Hassan mohammed.has...@jolla.com:

You don't need executable permission (x) for js files. Read bit is  
enough so the SDK is correct here.


I noticed that the missing scripts do not have read permission set  
which is the problem.


I have no idea how it happened though.

Cheers,

Re: [SailfishDevel] Two prolblems: #1 Telepathy qt5 and #2 OpenSSL


Hi UV

Many moons ago I wrote a blog on installing additional packages

http://flyingsheeponsailfish.blogspot.ch/2013/11/deploying-additional-packages-to.html

My project also uses Telepathy on Sailfish, so this may also help.  
Here is a link to the yaml file which included Telepathy stuff.


https://github.com/sailfishapps/landed/blob/master/landed26_QT5/rpm/landed26_QT5.yaml

Zitat von Yuvraaj Kelkar yuvr...@gmail.com:


Hello all.
I'm trying to port my application from Maemo/Harmattan to Sailfish.

Problem 1:
One of the dependencies is telepathy-qt.
In Maemo/Harmattan this used to be installable/searchable as
telepathy-qt4-devel

From what I understand, in Sailfish, I'm supposed to use telepathy-qt5.
I ssh'd into the mersdk VM and did a sudo zypper install telepathy-qt5
As I had assumed, this doesn't install it into the sb2 environment of course.

I added a PKGCONFIG += TelepathyQt5 to my pro file (found out from Google).
However that didn't work either.

I then entered the sb2 environment and tried to install telepathy-qt5.
This too didn't work: No root privileges.

What do I have to do to be able to use libtelepathy-qt5 ?

Problem 2:
Based on more Googling, I figured out that Sailfish does NOT provide
its own openssl library and expects users to use the statically
compiled version on their own.

I have since then gotten the non-heartbleed openssl, compiled it in
sailfish sb2 for static compilation and managed to link it against my
app.

The question is is this really the correct way to use the openssl library?
It seems unfriendly.

I really hope the answer to #1 isn't compile it yourself and use it.
I can do that, but then I'm not sure thats the right way of doing
things...

Thanks,
Uv

Hi Thomas

Earlier this year in addition to my normal day job I took over  
responsibility for a server farm of over 50 servers both real and  
virtual. Their clocks, system and hardware were all over the place.  
This lead to strange knock on effects, like Samba not being able to  
authenticate users via SSSD / LDAP.


In order to git the clocks under control again I was forced to find  
out much more about clock-skew {1} and NTP then I cared for. As a  
result I can be very boring on the subject. 8-)


While ntpdate is a valid pragmatic workaround, it remains a  
workaround, as a properly configured ntp daemon should automatically  
keep your system clock in sub millisecond sync. Be aware also that  
NTDATE is deprecated {2}. Instead you should use ntpd -gq


However if the time is already too far off the NTD may never be able  
to catch up (as normally it only makes small jumps {3), or even give  
up altogether.


When I encountered a server with clock(s) way off I used the set of  
commands below to get it back in line.


hwclock --show
date
service ntpd stop
ntpd -gq
hwclock --systohc --localtime
service ntpd start
hwclock --show
date

After that, if NTPD is properly configured, then NTP should be able to  
keep the server's system clock in line.

Hi David

As we are in danger of taking this thread in a direction that the OP  
CDW probably did not intend I'll keep it short(ish) 8-)


You are right that NTP is very tricky when VMs are involved. VMs need  
exactly the right NTP config to work properly (e.g. to jump the time  
quickly after a suspend).


The ultimate crime is to run an NTPD Server in a VM. The less said  
about that the better.


For those in the need of some nerdy bedtime reading there is an  
excellent document on the topic from VMWare:


http://www.vmware.com/files/pdf/Timekeeping-In-VirtualMachines.pdf

While it specific for VMWare, much of the content is relevant to other  
virtualisers (e.g. VirtualBox)

Personally I think you should use a virtualisation specific solution to time
sync if possible - it tends to cope better with virt specific issues like
suspend and migrate. eg VMs running on laptops. In this case the VM  
may not even

know that it was suspended since the virt layer does it, not VM pm layer and
hence cannot trigger special-case timesync handling.

Running ntp on all guests is required in some situations though (eg  
older xen).


Happy to hear any counter-arguments though

nb - in farm situations this also means that you simply run ntp on  
the physical

hosts and that's one less config pita on the guests :)

However if the time is already too far off the NTD may never be

This works but is suboptimal.

Make sure
  /usr/bin/VBoxService -f
is running in the guest; it manages time sync.

Also https://www.virtualbox.org/manual/ch09.html

Finally check your host is running the correct services and has all the right
modules built.

Hi,

As this is getting very confused and we are mixing connecting  
devices to the Jolla and connecting the Jolla to the pc.


So which one is it?

Thank you guys.
Indeed devel-su works.
I have attached the devices, but the first problem is that the
connection does not supply power (the devices stay dead).


So you connected some device to your Jolla?


As far as I know, a usb connection should always have power, but it is a
bit beyond my kowledge. Do I need another plug?


This is not true. All depends on context, what you plug into what etc...

In general if you plug in a device into a USB host (like your  
average USB port on your pc/laptop) you should be able to expect  
power from it.


In the case of a phone this is usually a USB device, so it expects power.

And in the OTG case it gets complicated. Here the device is able to  
switch between host and device mode. And will supply power if it is  
playing host.



On other linux/MeeGo systems there was always power...
and dmesg would give:

Use Qserialport on ttyUSB0 and ready you are.


This looks like plugging in a serial device into a PC. Do you want  
your Jolla to expose a serial port? That is definitely possible and  
easy.


Do you want your Jolla to read data from some serial port with a  
serial to USB adapter then you're getting in a very complicated world.


Unless you can explain what you actually want there is little we can  
do to help.

Thanks Chris and others,
Indeed I need to use an external USB GPS and some other USB sensors.

All communicate via serial ports.
I gave the dmesg output txt as it is on other linux/MeeGo devices to

Never heard about OTG, and never had to use it for my app.
Don't know why is there a difference between Sailfisch and MeeGo.

My questions are now:

Can I enable power on the USB port? (escape would be a battery  
powered USB hub)
Will Sailfish automatically set a up a /dev/ttyUSBsomething when the  
device (like an external GPS) is plugged in?


I will rephrase my question about adding the Qtserialport as a more

devices to the Jolla and connecting the Jolla to the pc.


So which one is it?

Thank you guys.
Indeed devel-su works.
I have attached the devices, but the first problem is that the
connection does not supply power (the devices stay dead).


So you connected some device to your Jolla?


As far as I know, a usb connection should always have power, but it is a
bit beyond my kowledge. Do I need another plug?


This is not true. All depends on context, what you plug into what etc...

In general if you plug in a device into a USB host (like your  
average USB port on your pc/laptop) you should be able to expect  
power from it.


In the case of a phone this is usually a USB device, so it expects power.

And in the OTG case it gets complicated. Here the device is able  
to switch between host and device mode. And will supply power if  
it is playing host.



On other linux/MeeGo systems there was always power...
and dmesg would give:

Use Qserialport on ttyUSB0 and ready you are.


This looks like plugging in a serial device into a PC. Do you want  
your Jolla to expose a serial port? That is definitely possible  
and easy.


Do you want your Jolla to read data from some serial port with a  
serial to USB adapter then you're getting in a very complicated  
world.


Unless you can explain what you actually want there is little we  
can do to help.

Re: [SailfishDevel] show/hide pulley menu items

2014-03-11 Thread christopher . lamb

It can be very difficult for the beginner to distinguish if a given
QML element if pure Qt, or from a component set like Silica. I
remember struggling with this in the days of Harmattan.

It would be very helpful if the Silica documentation linked the Qt
Documentation, and showed inherited properties etc.

Yes there is a danger of link rot, and it is not that hard to find the
same information via google, but a direct link to the correct version
of the Qt Docs would make life a little easier.

Re: [SailfishDevel] How to debug Julla


Hi Tony

I initially had great problems upgrading my Jolla, installing stuff

After lots of hunting around, experimentation and measuring, I

[SailfishDevel] QtContacts: phoneNumbers.length attribute gets lost when copied to ListModel


Hi All

I have come across some strangeness using QtContacts 5.0 on Sailfish.

For various reasons partially lost in the mists of time, I copy  
contacts (or rather a subset of contract roles) from the ContactModel  
to a a normal ListModel.


One of the roles copied is phoneNumbers. This has a child property  
length indicating the number of phoneNumbers available for the  
contact.


phoneNumbers.length is available (defined) direct from the  
ContactModel, but is undefined when I try to use it from the  
ListModel. So the console.log in the function appendContact() gives a  
valid result, but the console.log in populate() gives undefined.


Other properties, including the phone numbers in phoneNumbers are  
defined when accessed from the ListModel.


Equivalent code works in Haramtatan / Qt 4.7.4 Mobility 1.2


import QtContacts 5.0

ContactModel {
id: phoneContactsModelInternal
}

ListModel {
id: localContactModelInternal
function populate() {
clear();
for (var i = 0; i   
phoneContactsModelInternal.contacts.length; i ++) {

appendContact(phoneContactsModelInternal.contacts[i]);
console.log(checking number of phoneNumbers:  +  
localContactModel.get(i).phoneNumbers.length);

}
}
function appendContact(contact) {
localContactModel.append({contactId: contact.contactId,
  displayLabel: contact.displayLabel.label,
  phoneNumbers: contact.phoneNumbers,
  phoneNumbersCount:  
contact.phoneNumbers.length});
console.log(appending:  + contact.displayLabel.label +  
, numbers:  + contact.phoneNumbers.length)

}
}

Any ideas?

Re: [SailfishDevel] How to debug Julla


Hi Jonni

In my case getting rid of the latency in my home network seemed to do  
the trick. Having got the latency down to normal levels, I was able to  
upgrade the phone, use the store, activate developer mode etc. without  
a hitch.


Interestingly though, the phone is more than 1.5 mins behind real  
time. This raises the question, what is supposed to regulate time on a  
Jolla? Should not reasonably accurate time be available from the GSM  
signal?


PkCon shows that ntpdate is available, but not ntpd (and given that  
the phone will not always have an active udp network, ntpd would  
probably not be much help anyway).

time.


Chris

Zitat von Jonni Rainisto jonni.raini...@jolla.com:

Yes, usually you get accurate time from your GSM network depending  
on your operator. Sometimes users do start the phone without SIM  
attached, and in that case people can forget 1970 or some other  
wrong year in the device. In future updates there are improvements  
to automaticly fetch time also from ntp servers (don't remember if  
that was already included in 1.0.3.8).

You can use qmlRegisterType to pass the Info of the C++ class to QML
like this in the cpp:

#include bloomfilters.h

int main(int argc, char *argv[])
{
   // Get App and QML-View objects
   QScopedPointerQGuiApplication app(SailfishApp::application(argc,
argv));
   QScopedPointerQQuickView view(SailfishApp::createView());

   // Register Bloomfilter Class
   qmlRegisterTypeBloomfilter, 1(harbour.myapp.Bloomfilter, 1, 0,
Bloomfilter);

   // Prepare the QML
   view-setSource(SailfishApp::pathTo(qml/bloomfilter.qml));
   view-show();

   // Run the app
   return app-exec();
}

Afterwards you can create a Bloomfilter-Object in QML:

Bloomfilter {
   id: bloom
}

and use the methods with

bloom.insertElement(myelement)

I hope this helps.

Re: [SailfishDevel] Starting point for building packages


Sali Tobias

The Sailfish SDK / Qt Creator does much of the hard work for you.

Dependencies on other libraries are specified in the .yaml file. In  
the archives of this forum you will find many posts on this issue.


I suggest you start with a default Sailfish project, then gradually  
move in code from you ownCloud app.

here: http://doc.owncloud.org/desktop/1.5/building.html


But now I'm looking for a hint on how to build software for  
SailfisOS. The SDK is up and running, and now? The howto's are all  
about how to create a new software, but not about how to build and  
package an existing one.
I know how to build software on linux: ./configure; make; make  
install. (And resolve needed dependencies). How can this three

Thanks for any hints on getting started.

Two things:

  1. Call setContextProperty() right before before

  setSource(), so it's

already available when the QML content is loaded.
  2. Use lowercase for context property names

  (bloomfilters instead of

Bloomfilters). In some places, QML interprets IDs

  starting with an

upper case letter as a type name, and that won't work

  then, therefore

stick to lowercase.

Could it be so that on device exactly QML engine is somehow always used
separately from your c++ execution context.. no it doesn't make sense.

It would be nice to have some logs-to-file way working in production with

DEFINES in qmake adds additional defines (-D) to the cflags used to build

these defines, so your adding them won't affect console.log (whose C++

If you don't want debug prints, you need to install a message handler (you
say you've tried this and it doesn't work, I can't answer why that would be
the case, it should work, as it uses the same infrastructure).

No rooting (or jailbreaking) pr verboten-hacks required.

Just put the phone into developer mode. In theory any user can do this

Then you can install anything that will run.

However this route does imply that the user has some idea of what they

Hi All,



I have what I imagine to be a very common problem:



1.   There will be billions of people who own smartphones.

2.   I have a 100% native Linux C++ app that I would like a few of those
billions of people to use. These are my future customers.

3.   I do not necessarily want to use an app store of any kind, if I
choose not to use any.

4.   I would like for my customers to decide, at their own discretion,
whether to side-load my native app onto their smartphone by going to my web
site, and not an app store.

5.   I would like to avoid having my customers call my tech-support line
and listen on the phone for 30 minutes as one of my tech-support
representatives tells him/her how to root their phone so that they can
side-load my app.



In other words, I would like the same situation that exists now under the
desktop model, where anyone who owns a desktop computer has full discretion
of what they do with their computer, without (significant) restrictions from
the OS vendor.



I understand that Jolla allows 100% true native C++ apps, but I was unable
to determine, with a quick search on the WWW, whether Jolla allows 100%
native C++ apps under the acquisition model above.



Can anyone clarify? Is it true that the owner of a Jolla smartphone will be
able to determine for himself/herself whether to side-load a third-party
native application without jumping through hoops to bypass restrictions
created by the OS?



Regards,

[SailfishDevel] Recommended way to populate a LocalStorageDB from an external source

2014-02-03 Thread christopher . lamb


Hi All

An architectural question: What is the the recommended approach (and  
harbour friendly way) to populate a LocalStorageDB on the Jolla with  
data from an external source?


Some background to the question:

My app Landed depends on a LocalStorageDB. It was always clear to me  
that Landed would be a readonly client of the DB, and the business of  
populating the DB would fall to something else. Until recently that  
something else was a companion app LandedSettings.


But I was never happy with that solution, and it now seems to me that  
a Qt Desktop app would be much better suited to configuring /  
populating the DB. (more screen, better keyboard etc.).


This raises the question: How best to transfer the data populated in  
the Desktop app to the DB on the Jolla?


The Jolla's Documents folder (or a sub directory thereof) could  
clearly be used as as staging area. This is the approach that Wim  
takes with his Harbour-approved Checklists app.


But exactly how should this work? I see several possibilities, all  
with pros and cons.


a) The Desktop app creates a LocalStorageDB, and the entire DB is  
transferred to the Jolla. This means that Landed would have to deploy  
the DB on a file level, then access it via the LocalStorage api as  
normal.


b) The Desktop app dumps a human readable exchange file (csv, xml,  
json) which is picked up by Landed, parsed and converted to SQL  
INSERTS then called via the LocalStorage API


c) The Desktop app dumps an SQL script (a list of INSERT INTO  
statements) which Landed then executes


d) The Desktop app dumps an SQL script in the form of a javascript  
file, which is then dynamically loaded by Landed using dynamic QML


e) something I have not thought of ...

As further background, I tend to favour QML over C++, but use the  
latter where necessary (and am beginning to feel uncomfortably  
comfortable in that language ...).


I am aware that for any kind of file manipulation from QML I will  
probably have to resort to a C++ plugin. (Even this  
http://www.developer.nokia.com/community/wiki/Reading_and_writing_files_in_QML  
example from Nokia which sets out to provide file access without a  
plugin describes an implementation that is to my mind a c++ plugin!)


At the moment I favour option b) as the most likely to work and be  
accepted, with option d) as the wildcard probably wont't work, but  
might turn out to be the easy option.


Thanks in advance for your thoughts,

Chris

I will have to write some more code to spit out the sat ids to the

nothing more.


At the moment my hypothesis is based on the circumstantial evidence

Re: [SailfishDevel] QGeoSatelliteInfoSource in Sailfish

2014-02-01 Thread christopher . lamb


Hi all

A slight correction to my previous post

I think that the high number of Sats in View shown on the Jolla means  
that it is showing both GPS and Glonass Satellites, and thus gives a  
figure almost double of that I was used to from the Nokia N9 and  
classic GPS devices.


Comparing various devices I get the following readings:

Sats in use / Sats in View / Device / Technology

6 / 9 / Nokia N9 / GPS only

5 / 20 / Jolla / GPS and Glonass

15 / 21 / Samusung Galaxy Note 3 / GPS and Glonass

9 / Garmin GPSmap 60CSx / GPS only

So the Sats in View figure of the Jolla is plausible.

Interestingly the Jolla's Sats In Use figure - at least in the tests  
on my terrace this morning - is consistently lower than that displayed  
by the other devices. I show 15 for the Galaxy above, but have seen  
readings of 18 and 19.

Hi,

I'm trying to get satellite information using QGeoSatelliteInfoSource, but I

Sailfish is using Geoclue, and there is a commit in Qt for supporting the
Geoclue Satellite interface:



https://qt.gitorious.org/qt/qtlocation/commit/e09d297894a8b4ff9b06317169b5a9eb97aa7162


Is this missing in the Sailfish-Qt-packages? Is the satellite interface
missing in the Sailfish-Geoclue? Is it another problem? Can I access the
satellite information in another way?

Another small partly related problem I found then using the GPS is the
following: If you use QGeoPositionInfoSource the VerticalAccuracy and the
HorizontalAccuracy are always the same, is this normal behaviour?

Re: [SailfishDevel] ListView with SectionDelegate (Strange Behaviour)

2014-01-30 Thread christopher . lamb


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.

Re: [SailfishDevel] ListView with SectionDelegate (Strange Behaviour)

2014-01-30 Thread christopher . lamb


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.

Chris

I can also confirm that behaviour. In your example and also in an

Did you already file a bug or are you still investigating?

[SailfishDevel] App own C++ plugin equivalent to Silica Theme


Hi All

I would like to create a C++ plugin for my app to export common UX  
settings as constants to the QML side (Things like font sizes, margin  
sizes that reoccur throughout the app.)


In essence I want something very similar to the functionality offered  
by by the Silica Theme.


After some experimentation I have hit on a solution that both compiles  
and works. This is pasted at the bottom of this mail.


I have 2 questions:

1) Is there a more elegant solution to achieve the same goal?

2) From the C++ side, can I access the Silica them UX constants? e.g  
to set some of my constants based on Silica constants?

[SailfishDevel] Interacting with the Sailfish Software Input Panel from code


Hi all

Is there any way to interact with the Jolla Software Input Panel  
(Visual Keyboard9 from Code?


i.e.
Are any signals emitted when it opens / closes?

Are there any methods to open and close it?

Harmattan had things like panelOpen and closeSoftwareInputPanel();

So far in Sailfish all I have found is that from a QML TextArea  
element onClicked and onFocusChanged are emitted, giving an indirect  
indication that the keyboard has opened.

[SailfishDevel] Binding weirdness on Jolla device after deploy with screen locked


Hi all

I have come across some weird behaviour on the Jolla:

Bindings don't seem to work immediately after an app has deployed when  
the screen is locked.


To demonstrate this I have created the code snippet at the end of this  
mail. To reproduce, create a default Sailfish project, paste the code  
into FirstPage.qml.


My code has:
1) an Item dummy with an enabled property bound to applicationActive.
2) a BackgroundItem with an enabled property bound to dummy.enabled
3) a Label in the BackgroundItem with with text property bound to  
dummy.enabled


When the app is active, the label should display Correct Label

However, if the app is deployed when the screen is locked, on  
unlocking and activating the app
the label text shows Oops Wrong label even though console.log output  
suggests that the text has changed to Correct Label.


Also, when the backgroundItem is clicked, the highlight colour is not  
shown (but an onClicked event is generated).


The app behaves as expected (label correctly displayed, highlight  
colour shown) when:

a) The app is pushed to the left, and then reactivated,
b) The app is deployed while the screen is unlocked (immediately shown  
fullscreen),

c) The app is opened from the app icon direct on the Jolla,
d) The app is deployed to the Emulator.

Chris

Re: [SailfishDevel] Python and Qt Widgets development possible?


Hi Dietmar

Zitat von Dietmar Schwertberger maill...@schwertberger.de:



Switching to QML/Qt Quick seems a major effort and especially, it is  
very un-pythonic to use this mixture of two languages.


There is only one language here, QML, which is an extension of javascript.
Qt Quick is a set of components used by QML. This component set is  
further extended by the Sailfish Silica component set.


I did not find QML itself that hard to learn, and there are lots of  
examples and tutorials on the interweb.


The mix of 2 languages comes when need to do some heavy-lifting and  
have to fall back to C++. Having said that C++ and QML are well  
integrated.


Zitat von Dietmar Schwertberger maill...@schwertberger.de:



...there's quite some effort to stay compatible over
multiple platforms 


You have hit the nail on the head. Multiplatform coding is not easy,  
especially if you want to keep native interaction, and look and feel.  
We know that Sailfish is quite a bit different from any other  
platform. Multi-platform is not impossible, but it does involve  
compromises.


I have been working for some while to port a Harmattan app to  
Sailfish. For the most part I have got it working, but not without  
some obstacles. Off the top of my head (and without going into  
detail), here is a list of differences I found between these 2 platforms


1) Qt Version  4.7.4 -- 5.x

2) QtQuick version 1.0 -- 2.0

3) Mobility 1.2 -- Qt 5.0 equivalents

4) Project Template Files C++ main function, Pro file

5) Project structure

6) Sailfish look and feel, user interaction

7) Sailfish Specials: e.g Cover

8) Missing QML Components / Extra Components,

9) Component Property differences

10) Library differences inc. Bugs

11) Niggly Technical Stuff

11.1) How a javascript file imports a second javascript file

11.2) Location of LocalStorage DB

12) Harbour rules (somethings are technically possible, but not  
allowed to be harbour compliant)


13) etc

Re: [SailfishDevel] Binding weirdness on Jolla device after deploy with screen locked


Hi Ove

That's pretty much the behaviour I get, and the swipe to multitasking  
and back fixes things.


The behaviour 1s 100% reproducible  when the screen is locked during  
deploy, and never occurs when deploying to an unlocked screen.


That the problem to do with bindings is only a wild assumption on my  
part, it could be down to the screen not updating as you suggest.

Are you able to tell the difference between something like this, and  
the more straightforward issue of the app display simply not  
updating? I frequently experience the latter immediately after a  
deploy. If I click anything, or try to use the pulley menu, I can  
hear the sounds and get the console logs, but the display doesn't  
start updating before I swipe out to the multitasking view and then  
reactivate it. Everything works otherwise.

Re: [SailfishDevel] Qt Creator Code AutoCompletion in QML for C++ declarative plugins


Hoi Sven

thanks.

The problem (and it is a small one only) is limited to the

QtCreator's clean function wipes out the moc files, but seems to have  
no effect on auto-complete.

Hi,

try to build/run qmake from the menu and if that does not help,

The trouble is, I often refactor the C++ code as I add complexity

The trouble is, back on the QML side, QtCreator code-completion  
still suggests the original names long after these have been  
renamed or eliminated.


Is there any way to flush / update the code completion so it

Thanks, your guess is correct. I had not seen the option under Tools / C++.

Unfortunately it does not help either.

During breakfast I have found a solution: closing all projects and  
QtCreator, then reopening gives autocompletion with the correct  
updated properties / method names.

Re: [SailfishDevel] LED Flash functionality on a real Jolla

2014-01-25 Thread christopher . lamb


Mohammed et al

I have just posted the code of my demo Flashlight app to Github

https://github.com/sailfishapps/ThrowawayDemos/tree/master/Working/GSTTorch2

This uses Gstreamer, and in its current form is far from Harbour compliancy.

It exposes a torch to QML using the Jolla LED flash that can be turned  
on and off, and changed from Beam mode to Flash mode.


So far the main focus is on the back-end c++ part, as I require this  
functionality as part of my main app.


As and when time permits I will enrich this demo including:

* use of resource policy engine to arbitrate access to camera
* expose flash rate to QML as property so it can be changed from GUI  
(e.g. with a slider control).


Have fun

Chris

Hi Mohammed

thanks. I will try that later (am at work at the moment). I will also
need to look into the resource policy engine, as that is new to me.

Harbour entry is becoming less and less of a concern for me. My app
does too many things that are not considered kosher under the current
Harbour rules (sending SMS direct, use of QtContacts, LED access,
other Qt Libraries etc.)

As an aside, on Harmattan while I got the the Gstreamer route working
in developer mode, I never got it working when launching the app
direct from the device (and thus chose the QCamera approach). This was
probably down to AEGIS, but that should not be a concern on the Jolla.

This is not the recommended way but it's the only way to get flash
light to work but I have to
warn you that it wil prevent your app from entering harbour. You
will also have to make use
of resource policy engine to arbitrate access to camera. Failing to
do so will lead to breaking

jolla camera app.

Simply replace subdevsrc with droidcamsrc and use droideglsink as
the sink and

it should work fine.

[SailfishDevel] LED Flash functionality on a real Jolla

2014-01-22 Thread christopher . lamb


Hi All

As many will know from previous threads, I am well on the way to  
porting an app for paraglider pilots.


A subsidiary yet still important feature {1} that I added to the  
Harmattan version is an emergency flash, using the phone's LED.


Now that I have got the app's main functionality ported and up and  
running on a real Jolla device, I am now trying to get this feature  
working too.


Unfortunately everything I try fails. But as there is a working  
flashlight app in the Harbour, it must be possible by hook or crock.


So far i have tried 3 solutions:


Solution 1)  A C++ plugin exposing QtMultimedia QCamera to QML

This is the solution that works in the Harmattan version of the app,  
and was therefore the first solution I tried to port to the Sailfish  
version.


When I start the flash I  get the following error:

QCameraPrivate::_q_error:171 - Camera error: The camera service is missing


Solution 2) QtMultimedia 5.0 Torch QML element

As QtMultimedia offers a Torch Element this seemed an easier and  
cleaner approach.


import QtMultimedia 5.0

Page {
id: page

Torch {
id: torch
power: 75   // 75% of full power
enabled: false   // off
onEnabledChanged: console.log(onEnabledChanged:  + enabled)
}

However this gives the following errors on app start up.

2014-01-21 Thread christopher . lamb


Hi All

When / why is a PKGCONFIG entry required in a Sailfish .pro file?

Is there a better way of specifying the same (e.g. via a .yaml entry)?

As an example, I am playing around with GStreamer. If I have the  
following entry n my .pro file then the project builds and deploys ok.


PKGCONFIG += gstreamer-0.10

However if the entry is missing, then I get the error:

gst/gstelement.h: No such file or directory

Re: [SailfishDevel] Project Kits lost on Target Refresh

2014-01-21 Thread christopher . lamb


Hi Juha

Thanks.

The kits are easily added again, and this is no problem if only one or  
two projects are open.


But I often have 5 or more open ...

Another irritating strange behaviour in QtCreator, again with several  
projects open, Is that If I have one project selected to build and  
run, but the highlight in the Project Explorer (top left pane of  
QtCreator) is on a file in a second project, then the build fails  
because it gets muddled up.


e.g below I am building GSTTorch, but the highlight is on a file in  
QMLTorch. It tries to build GSTTorch using files from QMLTorch!


As I am frequently switching between projects I encounter this error  
many times!

If my understanding of the behaviour of the Jolla GPS is correct, is
there anyway I can stop it giving me the old fix? It is important to
my app that the coords shown are as accurate as possible, otherwise a

This is a feature in Qt Positioning. Only the coordinates and timestamp are
saved. Use the timestamp to check if the location data is old. The accuracy
values of the position will be NaN.

2014-01-19 Thread christopher . lamb


Salut

Damien

I am not sure If I have understood your question, but I think you are  
asking about differences in direction from the QtSensors Compass and  
the the QtPositioning PostionSource elements.


1) The Compass Azimuth shows the direction the top of the device is  
pointing to (so it will change as your rotate the device).


2) The PositionSource shows a direction based on the direction the  
device is travelling (irrespective of where the device is pointing).


http://qt-project.org/doc/qt-5/qgeopositioninfo.html

Similar to 2) The speed shown by a GPS is absolute, irrespective of  
how the device is pointing. Some years ago I was coastal soaring on  
the coast of South Africa when the wind picked up, and got to the  
point where it was at (and possibly just above) the maximum speed of  
my paraglider. Flying fully into the wind, pushing maximum speedbar  
the GPS was showing speeds of 0.5 - 1 Km, and it was very difficult to  
tell if this was fowrards or backwards - but it was most likely the  
latter.


Cheers

Chris



Zitat von Caliste Damien dcali...@free.fr:


Bonsoir,

Le dimanche 12 janvier 2014, christopher.l...@thurweb.ch a écrit :

Marcel used the Compass element from QtSensors for azimuth.

Ok, I understand, but I'm still wondering :
- QtSensors and compas will provide the azimuth of the device, so
acting it like a compas, for instance, top of the device is pointing to
the north.
- QGeoPosition is providing GPS info with latitude and longitude, and I
was thinking that the direction attribute was in fact the first
derivative of the position, which is different from the compas return
value, for instance I'm moving west while pointing top of device to the
north.

So how to get the first derivative of GPS position, deriving it by
hand ? Like calling the azimuth method on the two last GPS fix ?

Have a nice week,

Re: [SailfishDevel] Detecting if running in emulator/debug mode in QML

2014-01-18 Thread christopher . lamb


Hi Antoine

Your point is valid, in the old days of the N9 Simulator I was able to  
write code to detect the simulator vs real device.


But should it be necessary?

Why should we need to detect a difference between an Emulator /  
Simulator, and a real device?


Probably because of weaknesses in the Emulator / Simulator.

In my humble opinion, it would be much better if the Emulator was so  
good that from an app developer's point of view there is no difference  
when running on an Emulator vs a real device.


I know that by it's very nature an Emulator cannot do everything a  
real device can (GPS, Sensors, Camera, LED etc. spring to mind), but  
the N9 Simulator was a good example of what is possible in this area.  
Indeed the only reason that I was forced to write code to detect the  
N9 Simulator was due to differences in font sizing.


Therefore I think Jolla's effort is best spent on providing an  
emulator that closely matches a real device, and in providing  
appropriate plugins / tools to plug the few remaining gaps (e.g a GPS  
simulating plugin).

Re: [SailfishDevel] Sharing a common OfflineStorage DB between multiple Sailfish apps.

2014-01-17 Thread christopher . lamb


Hi Thomas

Thank you for your answer.

Zitat von Thomas Perl th.p...@gmail.com:




If we can fix the offline storage path to be correct everytime,  
we’ll probably introduce these changes into libsailfishapp, so that  
application developers don’t have to worry about manually setting  
this all the time (and you can still override this if you want, but  
you should not [need to]).




Does this not work already? If I did not explicitly call  
setOfflineStoragePath, the DB was created happily enough in a  
subdirectory of the app without me having to do anything.



Yesterday I experimented further, and arrived at this using QStandardPaths:

QString storagePath =  
QStandardPaths::locate(QStandardPaths::GenericDataLocation, QString(),  
QStandardPaths::LocateDirectory) + landedcommon;

view-engine()-setOfflineStoragePath(storagePath);

What are the pros and cons of using QStandardPaths as opposed to XDG  
Environmental Variables?



Zitat von Thomas Perl th.p...@gmail.com:



but append  the name of your application (harbour-myapp) to the  
path, so that all your application-specific data ends up there.


In my specific case I want this data to be available to a family of  
apps, which implies that I can't really use the app name as you  
suggest. I think I could either
a) use something like landedcommon as above - which is not the name  
of any of the apps in the family.
b) use the name of the primary app in the family. But this would mean  
that the secondary apps would have hard-coded references to an  
external app (not $APPNAME).
c) ensure that all apps in the family follow a standard naming pattern  
(e.g. harbour-landed-pilot, harbour-landed-settings,  
harbour-landed-recovery), and then create the common directory as a  
substring of $APPNAME.


This raises a greater architectural question: How should families of  
closely related apps be structured?

a) As one package, but with multiple executables

b) As separate packages, but able to share stuff within the family  
of apps: e.g. config data / local storage, shared libraries.
The shared libraries is especially important: Given the restrictive  
harbour rules we have to bundle not-yet-kosher libraries within an  
app. It would wasteful to have to repeat this for each member of an  
app family if they use the same libs.


In my case each of the apps is a full app in its own right, with a  
GUI. Others have raised similar questions about app-and-daemon pairs.

[SailfishDevel] GPS initially shows old location

2014-01-17 Thread christopher . lamb

This is the behaviour I am observing.

At the moment I am sitting in an office building, which has poor GPS

[SailfishDevel] Fwd: Sharing a common OfflineStorage DB between multiple Sailfish apps.

2014-01-16 Thread christopher . lamb


Hi all

This morning on the train on the way to work I tried the following to  
change the location of the offlineStorage DB:


The c++ main function of the demo app CreateDBQt5 now looks like this:

int main(int argc, char *argv[])
{
QScopedPointerQGuiApplication app(SailfishApp::application(argc, argv));
QScopedPointerQQuickView view(SailfishApp::createView());
qDebug()  offlineStoragPath orig:
view-engine()-offlineStoragePath();
 
view-engine()-setOfflineStoragePath(QString(/home/nemo/.local/share/landed25_QT5/QML/OfflineStorage  
));
qDebug()  offlineStoragPath new:
view-engine()-offlineStoragePath();

view-setSource(SailfishApp::pathTo(qml/CreateDBQt5.qml));
view-show();
view-showFullScreen();
return app-exec();
}

This gives the following Application Output:
[D] main:42 - offlineStoragPath orig:   
/home/nemo/.local/share/CreateDBQt5/QML/OfflineStorage
[D] main:44 - offlineStoragPath new:   
/home/nemo/.local/share/landed25_QT5/QML/OfflineStorage


The database is indeed created in  
/home/nemo/.local/share/landed25_QT5/QML/OfflineStorage, and is  
accessible to the app landed25_QT5


Note the order of the view-engine()-setOfflineStoragePath... and  
view-setSource... calls is crucial. If the setSource comes first,  
then the QML is initiated before the storagePath is changed!


In my next experiment I will try to change the storageLocation to  
something like QStandardPaths::GenericDataLocation.


The question on harbour acceptability remains ...

Chris

between multiple Sailfish apps.

An: Sailfish OS Developers devel@lists.sailfishos.org

Hi all

Is it possible to steer where a QML application stores its  
OfflineStorage Database?


I have a family of applications that share a common OfflineStorage  
Database. This works well on Harmattan, and on the early Sailfish  
Alphas without me having had to do anything special at all.


In the early Sailfish Alphas OfflineStorage DBs were stored in a  
common location, and thus could be easily shared.

/home/nemo/.local/share/data/QML/OfflineStorage/Databases

Now on the real Jolla, I find that the standard DB storage location  
has changed, and DBs are now put in a subdirectory of the  
application's installation folder. e.g.


/home/nemo/.local/share/landed25_QT5/QML/OfflineStorage
/home/nemo/.local/share/CreateDBQt5/QML/OfflineStorage

This means without some magic, Sailfish apps can no longer share DBs.

In C++ there is a property offlineStoragePath, and a setter method  
setOfflineStoragePath().


http://qt-project.org/doc/qt-5/qqmlengine.html#offlineStoragePath-prop

I might be able to use this to change the location of the DB, e.g to  
one of the Qt StandardLocations:


http://qt-project.org/doc/qt-5.0/qtcore/qstandardpaths.html#StandardLocation-enum

But setOfflineStoragePath() appears not to be directly available to QML.

http://stackoverflow.com/questions/14209585/how-to-set-custom-offline-storage-path-from-javascript-in-qtquick

So I guess I could call setOfflineStoragePath in each apps' main cpp file.

Or maybe I could even write a declarative plugin to expose  
setOfflineStoragepath to QML, but that is probably overkill as it  
would instantiate QQmlEngine - just t o set a path.


Or is there a better way? Are there any Harbour entry considerations  
to an app creating / accessing a DB somewhere other than in its own  
folder?


Thanks

How did you confirm this? Presence of the Location icon on the lock screen?


I compared this to my Nokia N9. On that device if an app using the GPS
exits (e.g. the user closes it), then the GPS stops soon after that
app has exited (even if the app does not explicitly shut the GPS down).

On the N9 this even works with multiple apps open using the GPS. In
this test, when the last GPS-consuming app exits, the GPS shuts down.


This is expected to work. Both the Geoclue master and the provider processes
monitor DBus disconnections and will clean up any associated interfaces. The
provider processes will then close 30 seconds after there are no more
connections.

How to test that geoclue-master is working:

Run

/usr/lib/qt5/bin/qdbus org.freedesktop.Geoclue.Master | grep
'/org/freedesktop/Geoclue/Master/client' | wc -l

to see how many processes have started positioning.

Run the above command, expect 0
Run sailfish-maps
Run the above command, expect 1
pkill -9 sailfish-maps
Run the above command, expect 0

It is harder to test this functionality in the providers as the number of
connections are not readily available.

Can you check whether there are any client interfaces exported by geoclue-
master with the above command. Also what geoclue processes are  
running (ps aux

| grep geoclue).

Re: [SailfishDevel] Device deployment problems (SSH connection dies)

2014-01-13 Thread christopher . lamb


hi Jaako

As you have the problem with both Wifi and USB, it does sound like  
something to do with the device.


But for what it is worth, have you tried a different USB port?

Yesterday evening I was doing quite a bit of development with both my  
Jolla and my N9 in developer mode connected via USB at the same time.  
Mostly this worked, but I soon found that while the right-hand USB on  
my MacBookAir always worked reliably, the lefthand port was a bit iffy  
- sometimes I could connect, sometimes not, and would have to plug and  
unplug, swap cables and devices. It may also be that the lefthand port  
is more sensitive to particular USB cables.


Chris


Zitat von Jaakko Koskenkorva jaa...@11latoa.com:


I've been terribly frustrated by erratically working deployment to device
from the SDK.
It seems that the SSH connection dies frequently i.e. compile output shows:

ssh: connect to host 192.168.2.250 port 22: Connection timed out

rsync: connection unexpectedly closed (0 bytes received so far) [sender]

rsync error: error in rsync protocol data stream (code 12) at io.c(226)
[sender=3.1.0]


...and application output shows:

SSH connection failed: Timeout waiting for reply from server.

This usually happens after 1-2 deployments, after which device does not
respond to ssh or ping.
Things that can help in this situation (when using USB):
1) Reconnect USB cable
2) Increase timeout
...but I've yet to find a permanent solution.
This also happens over WLAN with same symptoms, in this case re-connecting
device to wifi router helps. Initially I thought that Ubuntu connection
management was confused by the USB ethernet connection, but since WLAN has
this problem too I'm thinking it's something in the device end?

I'm using Ubuntu 13.10 64bit, latest SDK and v1.0.2.5 on device.
Any ideas?

Hi kaa

could you explain more exactly how you are expecting Assisted GPS to work?

It sounds like you are expecting it to show changes in position before  
a GPS fix has been acquired.


My understanding is that A-GPS is intended to get a useable fix  
faster. If you know roughly where you are, it is easier / quicker to  
calculate exactly where you are. Then once you have an accurate fix  
using the GPS signal it is easier to spot and track small changes.

If the mobile data was really off, and not accessed or reactivated

Where mobile-data is permitted, then the GPS can use the A

For qml you will need qt5-qtdeclarative-import-sensors and  
qt5-qtsensors. The blog post above should give you a number of ways to  
get these installed, including via the yaml file.



If these are missing on your target then (on your target):

pkcon install qt5-qtdeclarative-import-sensors

This should install both packages.

Hi,

I'm still stuck with this. Back to the basics...

In my qml, I have added:

import QtSensors 5.0 and used Accelerometer.

Fine. But On deployment, I get an error: module QtSensors is not installed

I think I have to edit something in my .pro file: I tried
CONFIG += qt5-qtsensors

but it didn't work.

Maybe I should also make changes in the rpm yaml, although I think as it
is available by default, I shouldn't.

Could someone give me a pointer on putting Qt / qml modules in my
project classpath ?

Thanks in advance,
Franck

So: is QAccelerometer available in Sailfish SDK ?
If not, is it planned ?
Or is there another way to get this kind of features ?


 They're part of the QtSensors module which is available in the
packages: qt5-qtsensors and qt5-qtdeclarative-import-sensors (for
QML support). They're both on the Harbour approved list, so you don't
need to worry about bundling them with your app or anything.

 I'm currently using the QML Accelerometer element in a game, so I can
confirm it works correctly.

Cheers,
 Mike.

Re: [SailfishDevel] qml PositionSource element gives error: QMetaMethod::invoke: Unable to handle unregistered datatype 'QGeoPositionInfo'


Hi All

In an attempt to track down the source of this problem, and possibly  
even solve it, I have created a throwaway demo posted to Github under:


https://github.com/sailfishapps/ThrowawayDemos/tree/master/Kaputt/PositionSourceDemo

The demo is basically a standard Sailfish new project, with a QML  
PositionSource element added to FirstPage, and the start() method  
called in a Component.onCompleted on that Page.


To actually get into the nitty-gritty of the code where the problem is  
likely to be, I have also copied in C++ code from QtPositioning. I am  
not sure if this identical to the code used in the Sailfish build of  
Positioning, but it is probably close enough. This in-line  
PositionSource element is imported by import PositionSource 5.2


Switching between the standard import and the in-line import is by  
comment in / out the import statement(s).


Of course, the problem may not be in the code at all, maybe I am  
missing some essential package or plugin on my Jolla ..


Grüsse

Chris

Hi Alejandro

My understanding is that although the version is quotes as 5.1, it  
is actually a not quite finished 5.2


In the target there is a 5.2.0 subdirectory:

/Users/christopherlamb/SailfishOS/mersdk/targets/SailfishOS-armv7hl/usr/include/qt5/QtPositioning/5.2.0


import QtPositioning 5.2, import QtPositioning 5.1, and import  
QtPositioning 5.0 all give me the same error.


Whereas something like import QtPositioning 5.7 gives module  
QtPositioning version 5.7 is not installed

Re: [SailfishDevel] qml PositionSource element gives error: QMetaMethod::invoke: Unable to handle unregistered datatype 'QGeoPositionInfo'


Hi All

The plot thickens!

Marcel very kindly posted his code using PositionSource in QML.

https://github.com/balta3/sailfish-gpsinfo

So I loaded up Marcel's app, and it worked!

Then I scanned the application output, and found:

QMetaMethod::invoke: Unable to handle unregistered datatype 'QGeoPositionInfo'

Exactly the same error that my app was giving

So it looks like this error is a bit or a red herring in that it does  
not stop the PositionSource from working. But the error had stopped me  
from further integrating the PositionSource element.

Re: [SailfishDevel] qml PositionSource element gives error: QMetaMethod::invoke: Unable to handle unregistered datatype 'QGeoPositionInfo'


Hi Bob

Thanks for the confirmation that things work for you.

I too now suspect that it is a ghost problem. The trouble is, as soon  
as I saw the error I just assumed that it was a real problem and did  
not even bother to try and display Position info. To mix metaphors it  
led me up the garden path on a wild goose chase ...


Chris

Zitat von Bob Jelica sailf...@jelica.se:

I get the same error/warning in my app, without it affecting the  
app. At least not enough for me to dig into the error.

I still get the GPS fix, location etc, so my app is usable.

Would love to find out if it’s a real problem or just a ”ghost”  
problem, but thus far it seems like it’s not going to give me too  
much problems :)

Hello,

Do you have the direction attribute of QGeoPositionInfo that is set

always get false.

Re: [SailfishDevel] qml PositionSource element gives error: QMetaMethod::invoke: Unable to handle unregistered datatype 'QGeoPositionInfo'


HI Aaron

Thanks for this. I am glad to hear a fix is underway.

I was about to play around with solution like the one you suggest  
until others in this mailing list provided me with demo code that  
indicates that despite the error, the PositionSource element seems to  
work!


If so, is this actually a ghost error that we can ignore for the moment?

This is a problem with the Qt Geoclue positioning plugin, it fails  
to register

the data type. I have submitted a fix upstream [1]. In the meantime you can
work around it in you application by calling

qRegisterMetaTypeQGeoPositionInfo();

prior to creating a position info source.
