| dale_ | I have an app with C++ backend which tries to access the screen service to change brightness via the system DBus, but I get apparmor errors. Does anyone know how to write the click apparmor file to get around this? | 05:01 |

| Nymerea | Hello guys | 08:07 |
| Nymerea | I've ear than some expert are here in european office hours | 08:07 |
| Nymerea | I need help with my application | 08:07 |
| Nymerea | If some appdevs can help me, I will be very honoured | 08:09 |
| davidcalle | Nymerea, hi, blocking on something with your app? | 08:22 |
| Nymerea | davidcalle, yep I have some trouble | 09:29 |
| Nymerea | 1) my application doesn't work on smartphone but work on desktop | 09:30 |
| Nymerea | 2) my camera is rotated by 90° by default | 09:30 |
| Nymerea | I want create a simple application that read barcode | 09:31 |
| Nymerea | https://github.com/Nymerea/uBarcodeReader/tree/feature/autoCapture | 09:31 |
| brunch875 | Is there a way to make QApplication work on the device? I want to skip QML and use the graphics view framework... | 09:32 |
| brunch875 | Or... any non-horrible way to do qtquick on c++ entirely? :P | 09:32 |
| davidcalle | Nymerea, let me give it a try | 09:33 |
| Nymerea | brunch875, http://doc.qt.io/qt-5/qtqml-cppintegration-topic.html ??? | 09:34 |
| Nymerea | davidcalle, dont forget to use feature/autoCapture branch | 09:34 |
| Nymerea | davidcalle, The application run on smartphone, but when I click on image I have a referenceError | 09:35 |
| brunch875 | I've considered that, but I thought it might be a pretty bad idea | 09:35 |
| brunch875 | but I'm glad someone has the same second-opinion! | 09:35 |
| Nymerea | this error doesn't occur in desktop | 09:35 |
| Nymerea | brunch875, personnaly I think QML is much better than C++ for writing UI | 09:35 |
| brunch875 | thing is I want to port one of my games from scratch | 09:36 |
| brunch875 | feels like QML gets on the way | 09:36 |
| brunch875 | the graphics view framework seems perfect for the job, but I can't get it to work on utouch | 09:37 |
| brunch875 | maybe I should wait a bit for mir and convergence? :) | 09:37 |
| Nymerea | brunch875, scope are entierly written in c++ | 09:38 |
| Nymerea | so it shouldn't be a problem | 09:38 |
| Nymerea | (use only c++) | 09:38 |
| brunch875 | is there some source code I can peek at? | 09:39 |
| brunch875 | I sank in information yesterday... so extense | 09:39 |
| Nymerea | If you run ubuntu-sdk | 09:41 |
| Nymerea | you have some auto-generate source code that use c++ | 09:41 |
| davidcalle | Nymerea, sorry, I'm having an issue with my QtCreator, I can't add a device kit at the moment to test on my phone. I'll get back to you if I manage to fix that and test today :) | 09:45 |
| Nymerea | davidcalle, lot of problem with qt creator | 09:46 |
| davidcalle | Nymerea, in my case that's mostly a case of bleeding edge packages and SDK ones not being recent enough | 09:48 |
| Nymerea | But | 09:48 |
| Nymerea | Maybe you can help me with the error | 09:49 |
| Nymerea | I know exactly what happen | 09:49 |
| Nymerea | but I don't understand why | 09:49 |
| davidcalle | Nymerea, I can try | 09:49 |
| Nymerea | Okay, look my main.cpp : extense | 09:50 |
| Nymerea | https://github.com/Nymerea/uBarcodeReader/blob/feature/autoCapture/OpenFoodFacts/main.cpp ** | 09:50 |
| Nymerea | I give to my Qml file a reference : view.rootContext()->setContextProperty("qDecoder", &decoder); | 09:51 |
| Nymerea | In my Main.qml file, I use this reference | 09:51 |
| Nymerea | On desktop it's work properly but in smartphone i have : ReferenceError with qDecoder | 09:52 |
| Nymerea | davidcalle, any idea why it's happen ? | 09:52 |
| Nymerea | ReferenceError : qDecoder is not defined | 09:53 |
| davidcalle | Nymerea, that's odd. I don't see anything wrong with it. I guess someone with more cpp experience on the device can help, mzanetti? ^ | 09:58 |
| * mzanetti reads scrollback | 09:58 | |
| mzanetti | view.rootContext()->setContextProperty("qDecoder", &decoder); | 09:59 |
| mzanetti | should be: | 10:00 |
| mzanetti | view.engine()->rootContext()->setContextProperty("qDecoder", &decoder); | 10:00 |
| mzanetti | not sure why the first works at all | 10:00 |
| Nymerea | hum | 10:00 |
| mzanetti | maybe it's the same... dunno | 10:00 |
| mzanetti | Nymerea, what does this better than Tagger? | 10:01 |
| Nymerea | The barcorde reader is just the proof of concept | 10:01 |
| Nymerea | OpenFoodFacts is read barcode from food a get nutritional information | 10:02 |
| Nymerea | I cannot use tagger as "provider of barcode" | 10:02 |
| mzanetti | mhm... | 10:02 |
| Nymerea | and barcode reader is to hard to use when you haven't a lot of experience in c++ developpement | 10:02 |
| mzanetti | Authenticator does | 10:02 |
| Nymerea | what is authenticator ? | 10:03 |
| Nymerea | It's not installed by default on my device | 10:03 |
| mzanetti | https://uappexplorer.com/app/com.ubuntu.developer.mzanetti.ubuntu-authenticator | 10:03 |
| Nymerea | I don't want login by using qrcode | 10:04 |
| mzanetti | you do want a QR code scanner, no? | 10:06 |
| Nymerea | mzanetti, do you know why my camera is rotated by 90° by default ? | 10:06 |
| Nymerea | mzanetti, no, EAN8/13 scanner | 10:06 |
| mzanetti | yeah well... that's the *same* | 10:06 |
| mzanetti | from the scanner POV. it reads all | 10:06 |
| Nymerea | let me try | 10:09 |
| Nymerea | the problem is : authentificator is not installed by default | 10:09 |
| Nymerea | there is any way to install a third application as dependences ? | 10:11 |
| popey | clicks don't have dependencies | 10:12 |
| Nymerea | popey thank you | 10:15 |
| Nymerea | mzanetti, I've just looked your code source on launchpad | 10:20 |
| Nymerea | I didn't understand how you provide your QZBar dependences | 10:20 |
| Nymerea | because I use ZXing but it has very poor performances compare to Zbar | 10:21 |
| mzanetti | Nymerea, I use static linking | 10:25 |
| Nymerea | If I kew it before | 10:25 |
| Nymerea | I spent like 1 month with fuckin ZXing library | 10:26 |
| Nymerea | and tagger cmake was too complicated for me | 10:26 |
| Nymerea | (I mean qMake is so easy to read compare to cmake) | 10:27 |
| mzanetti | authenticator uses qmake | 10:30 |
| Nymerea | mzanetti, is it normal the camera is rotated by default ? | 10:44 |
| mzanetti | dunno | 10:44 |
| mzanetti | Nymerea, seems yes: http://bazaar.launchpad.net/~mzanetti/authenticator/trunk/view/head:/app/qml/ubuntu-authenticator.qml#L444 | 10:46 |
| Nymerea | mzanetti, no, if the smartphone is in portrait mode you rotate by 90° | 10:47 |
| Nymerea | that normal | 10:47 |
| Nymerea | but for me, by default it's rotated by 90° | 10:48 |
| mzanetti | I rotate -90, to compensate the 90 | 10:48 |
| Nymerea | yes, if it's in portrait mode | 10:49 |
| Nymerea | but by default i'm in "normal" mode | 10:49 |
| Nymerea | isn't ? | 10:49 |
| mzanetti | isn't portrait the normal one? | 10:49 |
| Nymerea | hum | 10:50 |
| Nymerea | maybe my english the problem :-D | 10:50 |
| Nymerea | mzanetti, you're rith : http://www.geckogeek.fr/wp-content/uploads/2010/09/LandscapePortrait.png | 10:51 |
| Nymerea | I'm very sorry | 10:51 |
| mzanetti | :) | 10:51 |
| mzanetti | no problem | 10:51 |
| Nymerea | I will check you're trick this afternoon | 10:51 |
| Nymerea | Thank you for you're help | 10:51 |
| Nymerea | Maybe I will re-use your code for reading barcode | 10:52 |
| Nymerea | because I didn't success to use zbar | 10:52 |
| Nymerea | mzanetti, I just tryed -90° | 10:56 |
| Nymerea | device.naturalOrientation === "portrait" ? -90 : 0 | 10:56 |
| Nymerea | and now it's rotated by -90° | 10:57 |
| brunch875 | urrrgh I'm still unable to paint a qtquick rectangle entirely on c++ | 10:58 |
| brunch875 | this api is harsh | 10:58 |
| Nymerea | actually, what ever the number is, the screen is rotated -90° | 10:58 |
| mzanetti | brunch875, not sure what you're trying to do | 11:03 |
| mzanetti | but wouldn't it just be subclassing QQuickPaintedItem and then just painRect() inside the paint() or update() method? | 11:04 |
| brunch875 | that's a great hint, thanks! I'm kinda lost | 11:05 |
| Nymerea | mzanetti, Okay I got it, I have "ReferenceError : screen is not defined" | 11:05 |
| mzanetti | you're missing an import I guess | 11:05 |
| Nymerea | mzanetti, you're right | 11:08 |
| Nymerea | Thank you for you're precious help | 11:08 |
| Nymerea | you're always right | 11:08 |

| dholbach | davidcalle, how are things in the deployment department? :) | 12:18 |
| davidcalle | dholbach, reverted everything to r122 :( Sent an email for help. | 12:40 |
| davidcalle | r122 because it's the one that deploys. | 12:40 |
| dholbach | :-/ | 12:41 |
| dholbach | davidcalle, r122 is without the mojo changes? | 12:41 |
| davidcalle | dholbach, yep, but it also has a bunch of extra files, like a db dump (it's not a clean pull from trunk at r122). Ideally, I should try to extract it, merge manually evertyhing we have done and try again with a tarball based on it. Haven't found time to do it yet. | 12:44 |
| dholbach | davidcalle, can Caio or anyone from webops help? | 12:46 |
| dholbach | it looks a bit like we're fishing in the dark :-( | 12:47 |
| davidcalle | dholbach, I know. Emailed caio, mike and jacek | 12:48 |

| jhodapp | mcphail, alright no worries, just make sure all of what you discovered is on the comment log for that bug | 13:49 |
| jhodapp | mcphail, learned a few things I'm sure :) | 13:49 |
| mcphail | jhodapp: absolutely :) Most of all, I learned that C++ and debuggers are a deadly mix :) | 13:50 |
| jhodapp | lol | 13:50 |
| jhodapp | indeed, C++ feels very insane at times | 13:50 |

| ubik__ | Helo, how can I detect screen rotation with QML? | 15:42 |
| ubik__ | (if it is vertical or horizontal) | 15:42 |
| ahayzen | https://developer.ubuntu.com/api/apps/qml/sdk-15.04/QtSensors.OrientationReading/ or just measure the width vs height of the page | 15:43 |
| ubik__ | thx | 15:43 |
| ubik__ | uhm | 15:59 |
| ubik__ | my app crashes, when i add the code from this page | 15:59 |
| ubik__ | isn't it possible to use accelerometer and OrientationSensor at the same time? | 16:00 |
| ahayzen | ubik__, what is the error it crashes with ? | 16:01 |
| ubik__ | Sdk-Launcher> Application started: 947 | 16:02 |
| ubik__ | Sdk-Launcher> Received a failed event | 16:03 |
| ubik__ | Sdk-Launcher> The Application exited, cleaning up | 16:03 |
| ubik__ | Sdk-Launcher> Finished | 16:03 |
| ahayzen | ubik__, there should be the actual apps output somewhere, maybe in one of the other panels | 16:03 |
| ahayzen | you have .. import QtSensors 5.0 .. at the top of the file right? | 16:04 |
| ubik__ | I have import QtSensors 5.2 | 16:04 |
| ahayzen | yup that should be ok | 16:05 |
| ubik__ | i try to uncomment my accelerometer | 16:05 |
| ahayzen | ubik__, if its a pure qml app have you tried running $ qmlscene path/to/app.qml ? | 16:05 |
| ubik__ | nope | 16:07 |
| ubik__ | I dont know how to debug | 16:10 |
| ubik__ | because im a newbie to ubuntu-sdk | 16:10 |
| ubik__ | but maybe my code is just wrong | 16:10 |
| ahayzen | if your using Qt Creator is there anything in the "application output" panel at the bottom? | 16:11 |
| ubik__ | http://pastebin.com/BYztNsED | 16:11 |
| ubik__ | yes, thats what i posted already | 16:11 |
| ahayzen | hmm you'd usually get something more useful than that | 16:12 |
| ubik__ | I just need to set colums = 1 and rows = 2 of the Grid when I rotate my device | 16:13 |
| ubik__ | It's something stupid, but I don't know how to do it | 16:13 |
| ahayzen | ubik__, when running the code you provided me... property string teststring: 0 .. fails with Invalid property assignment: string expected | 16:14 |
| ubik__ | oh | 16:14 |
| ubik__ | lol | 16:14 |
| ubik__ | :D | 16:14 |
| ahayzen | :-) | 16:15 |
| ubik__ | now my application starts | 16:15 |
| ubik__ | thx | 16:15 |
| ahayzen | yey no problem | 16:15 |

| taiebot | mzanetti cool update for kodimote. Would it be possible to put a next playing on this screen? http://i.imgur.com/h1hmm51.png it would be nice to have this info here. | 20:23 |
| mzanetti | taiebot, longpress | 20:52 |
| taiebot | mzanetti: i already know for this is just it would be intersting to know what will play next on this screen. | 20:52 |
| mzanetti | ah, i see | 20:53 |
| mzanetti | ok, will think about it | 20:53 |
| taiebot | mzanetti: yeah the long press shows me what play next but it starts a day in the past for me | 20:56 |
| mzanetti | taiebot, right... that's a bit odd. I can't really know where to scroll the list to without lots of fancy maths and I never found the motivation to do that | 20:57 |
| taiebot | mzanetti: yeah i do understand. If i had the skills would do a tvheadend scope (backend PVR for Kodi) it would be much more appropriate for TV channels | 21:00 |
