| nik90 | mzanetti: ping | 11:32 |
|---|---|---|
| mzanetti | nik90: pong | 12:00 |
| nik90 | mzanetti: hey I am hitting a weird issue with our base timezone model | 12:08 |
| nik90 | mzanetti: I created a C++ plugin just to send back the local date and time using QDateTime since it keeps track of the timezone change unlike the javascript date object. | 12:08 |
| nik90 | mzanetti: Everything seems to work except for one thing which is the localCityTime.offsetFromUtc() - worldCityTime.offsetFromUtc() value. We return this value in the timezone base model class. On changing the system timezone and then returning to the clock app, I notice that this value changes in the c++ side of things, however it doesn't update the value in | 12:09 |
| nik90 | the qml listview. | 12:09 |
| nik90 | mzanetti: any thoughts as to why that might happen? | 12:09 |
| nik90 | mzanetti: I am working on this at https://code.launchpad.net/~nik90/ubuntu-clock-app/implement-change-time-settings | 12:09 |
| mzanetti | nik90: isn't that the same issue again? | 12:09 |
| mzanetti | that returning QDateTime to qml doesn't keep timezone informations | 12:10 |
| nik90 | mzanetti: no because the localCityTime.offsetFromUtc() - worldCityTime.offsetFromUtc() value is a int64 value. On c++ when qDebug() it returns the correct value, however on qml that value is different | 12:10 |
| nik90 | mzanetti: so I am not interacting with qDateTime but rather just an int | 12:10 |
| mzanetti | hmm, ok... need to check the code | 12:11 |
| nik90 | mzanetti: in the timer update() function, we only do this roles << RoleTimeString; | 12:12 |
| nik90 | mzanetti: may be we need to add other stuff that also change like the RoleTimeTo, RoleDayTo | 12:12 |
| mzanetti | nik90: ah, yeah, true, you need to add each role you change | 12:12 |
| nik90 | mzanetti: do I do it like roles << RoleTimeString << RoleTimeTo; ? | 12:13 |
| mzanetti | yep | 12:13 |
| nik90 | thnx | 12:13 |
| mzanetti | nik90: if you're changing all of the roles, or most of them, you could remove the whole last argument in dataChanged, then it would always update all roles | 12:14 |
| mzanetti | its up to you to decide if you can affort refreshing also unchanged fields or not | 12:14 |
| nik90 | I am changing 3 out of 6, so I will do roles << RoleTimeString << RoleTimeTo to save on performance | 12:15 |
| nik90 | mzanetti: yay that worked | 12:16 |
| mzanetti | :) | 12:16 |
| Diogo | hi guys | 14:54 |
| Diogo | does some one know how to make MYSQL database conection with QML?? | 14:59 |
| Diogo | does some one know how to make MYSQL database conection with QML?? | 15:19 |
| nik90 | Diogo: Check out http://qt-project.org/doc/qt-5/qtquick-localstorage-qmlmodule.html | 15:33 |
| Diogo | nike90: i have c++ code, but i just dont understand it | 16:08 |
| qtros | Hi all | 16:25 |
| qtros | Which component should I use instead of standard WebView in UP? | 16:26 |
| nik90 | Diogo: I always wonder you change nik90 to nike90 :D...I don't get a notification if you type nike90 | 16:35 |
| Diogo | nik90: ok | 16:36 |
| nik90 | Diogo: I am not sure about accessing sql in c++, i haven't done it before | 16:37 |
| Diogo | nik90: i have a project with some code | 16:37 |
| nik90 | Diogo: but I am sure QT should have that in some form or the other | 16:37 |
| qtros | nik90 Hello) Can you please help me with using of "Ubuntu.Web" on desktop? | 16:38 |
| Diogo | nik90: the question is, that i dont understand the code | 16:38 |
| Diogo | nik90: look http://paste.ubuntu.com/7876122/ | 16:38 |
| nik90 | qtros: Hi | 16:38 |
| Diogo | nik90: http://paste.ubuntu.com/7876128/ | 16:39 |
| Diogo | nik90: i just needed some one to explain me what the code means, so i could move on and modify the way i need him | 16:40 |
| nik90 | qtros: I am guessing you have looked at http://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Web/ | 16:40 |
| nik90 | qtros: I haven't used it yet, so sry I don't know much about it | 16:40 |
| qtros | nik90 yep | 16:40 |
| nik90 | Diogo: ah ok, | 16:40 |
| * nik90 takes a look | 16:40 | |
| qtros | nik90 hmm... standard WebView is deprecated and nobody knows how to use new :D | 16:41 |
| nik90 | qtros: yeah, however the documentation at http://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Web/ seems quite limited. I would love to see some examples there :/ | 16:41 |
| nik90 | Diogo: ok so your code creates a mysql object in c++. Do you want to access the mysql object in c++ or in qml? | 16:42 |
| nik90 | Diogo: If you want to do all the sql commands in qml, it is better to look at the link I pasted earlier | 16:43 |
| nik90 | Diogo: on the other hand, if you want to use it in your c++ code, it seems ok | 16:43 |
| nik90 | Diogo: you will still need to add some functions for additonal functionality | 16:44 |
| Diogo | nik90: i dont understand c++ thats why i asked help | 16:45 |
| qtros | Diogo and what do you want to do with this code? | 16:45 |
| nik90 | Diogo: as qtros where do you want to use this code? In qml or c++ ? | 16:46 |
| Diogo | nik90: i've found out that the only possible way you can make the mysql contection in qml is using c++ | 16:46 |
| Diogo | qml | 16:46 |
| Diogo | nik90: qml | 16:46 |
| nik90 | Diogo: ok then check out http://qt-project.org/doc/qt-5/qtquick-localstorage-qmlmodule.html | 16:46 |
| nik90 | Diogo: that is sql in qml | 16:46 |
| nik90 | <Diogo> nik90: i've found out that the only possible way you can make the mysql contection in qml is using c++ | 16:46 |
| nik90 | ^^ that is plain wrong | 16:46 |
| Diogo | nik90: is it?? | 16:47 |
| nik90 | yes | 16:47 |
| Diogo | nik90: javascript cant make the conection | 16:47 |
| nik90 | Diogo: Did you read http://qt-project.org/doc/qt-5/qtquick-localstorage-qmlmodule.html ? | 16:47 |
| Diogo | nik90:i'm going to read it | 16:48 |
| nik90 | Diogo: they are using javascript to make the connection | 16:48 |
| Diogo | nik90: they are using sqlite | 16:49 |
| Diogo | nik90: imagin you have an app that requires you to do the login | 16:49 |
| Diogo | nik90: and the database with you data is on the server | 16:50 |
| Diogo | nik90: what type of DB woudl you use? | 16:51 |
| qtros | Diogo yes, remote connection only with cpp | 16:51 |
| nik90 | Diogo: then I would use MySQL since it is in a remote server | 16:51 |
| nik90 | Diogo: you didn't specify the remote server part earlier :) | 16:51 |
| Diogo | nik90: sorry | 16:51 |
| Diogo | nik90: about that | 16:52 |
| nik90 | Diogo: In that case, you will have to create a C++ plugin that you can import in your qml code. | 16:52 |
| nik90 | Diogo: However you will need to also set up cmakelists to ensure that the c++ gets built rproperly when running your app | 16:52 |
| Diogo | nik90: i have a huge problem now | 16:53 |
| nik90 | Diogo: In Qtcreator, in the create project wizard, you will have to choose "App with QML Extension Library" | 16:53 |
| Diogo | nik90: because i dont know how to program in c++ | 16:54 |
| nik90 | Diogo: you will have to learn I am afraid | 16:54 |
| nik90 | Diogo: I was in the same boat 2-3 weeks ago where I had to develop C++ plugins for the clock app. | 16:55 |
| nik90 | Diogo: I did some reading and eventually am getting used to it | 16:55 |
| Diogo | nik90: any good pleaces to learn it? | 16:55 |
| nik90 | Diogo: well if you want to learn C++, then http://www.learncpp.com/ should be good | 16:56 |
| nik90 | Diogo: however after that you will have to know how to develop with Qt C++ | 16:56 |
| Diogo | nik90: and did you see the voidream tutorials?? | 16:57 |
| nik90 | Diogo: ? | 16:57 |
| nik90 | Diogo: I knew a bit of c++ from high school, so I started to work straight on the Qt C++ part | 16:57 |
| Diogo | nik90: look https://www.youtube.com/watch?v=6KtOzh0StTc&list=PL2D1942A4688E9D63 | 16:58 |
| nik90 | Diogo: ooh yes, I saw some of his videos | 16:59 |
| Diogo | nik90: i've created the "App with QML Extension Library" to see the files | 17:01 |
| Diogo | and i see the backed.cpp | 17:01 |
| nik90 | backend.cpp | 17:01 |
| Diogo | nik90: and i see the backed.cpp in Myapp folder | 17:02 |
| Diogo | nik90: etc.. | 17:02 |
| nik90 | yup | 17:02 |
| nik90 | so basically the backend folder holds your c++ plugin stuff | 17:03 |
| nik90 | while your main qml code is in the app folder | 17:03 |
| Diogo | nik90: the new thing for me to is now the app folder and the .. folder | 17:03 |
| nik90 | Diogo: dont worry about the .. folder. It is part of cmake | 17:03 |
| Diogo | nik90: what is cmake? | 17:03 |
| nik90 | Diogo: it is sort of like an instruction list which tells the compiler what to do before running your app | 17:04 |
| Diogo | nik90: so i'll develope my c++ plugins in the Myapp folder right? | 17:06 |
| nik90 | Diogo: there should be already a sample C++ plugin class | 17:07 |
| nik90 | Diogo: you can just change that with your own class | 17:07 |
| Diogo | nik90: so i'll change mytype.cpp and mytype.h for that right? | 17:08 |
| nik90 | Diogo: yeah | 17:09 |
| Diogo | nik90: you are the best man | 17:10 |
| Diogo | nik90: for a hole day i've asked on forms and no one did say anything | 17:10 |
| Diogo | nik90: and now when i ask to the community of the OS i love so muhc they help me | 17:12 |
| nik90 | Diogo: make sure you accordingly change the CMakeList.txt file when you rename the mytype.cpp or mytype.h files | 17:12 |
| nik90 | Diogo: no worries | 17:12 |
| nik90 | Diogo: just push this to your github or launchpad branch and then we can better help with debugging | 17:13 |
| Diogo | nik90: i'm going to study c++ for a day or 2 and then i'll begin to put everything in github | 17:15 |
| nik90 | ok | 17:15 |
| Diogo | nik90: and then i'll tell you :) | 17:18 |
| Diogo | nik90: thanks for everything :D | 17:18 |
| nik90 | Diogo: yw | 17:19 |
| qtros | Hi all | 17:37 |
| qtros | Can someone tell how to use QML package "Ubuntu.Web" on desktop? | 17:37 |
| qtros | Can someone tell how to use QML package "Ubuntu.Web" on desktop | 17:54 |
| mhall119 | qtros: http://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Web.WebView/ | 19:47 |
| mhall119 | qtros: you probably need to be running Utopic on the desktop to use it though | 19:47 |
| mhall119 | qtros: also make sure you have qtdeclarative5-ubuntu-web-plugin installed | 19:48 |
| mhall119 | hope that helps, /me is going afk for a bit | 19:50 |

| qtros | mhall119 ping | 20:29 |
| mhall119 | qtros: pong | 20:58 |
| qtros | mhall119 "you probably need to be running Utopic on the desktop to use it though" - does it mean that I always must develop for UP only on latest version of Ubuntu? ... | 20:59 |
| qtros | mhall119 what if I prefer stable releases? | 20:59 |
| mhall119 | qtros: once we have phones on the market there will be a stable release, right now "stable" (Trusty) is missing some many needed features that you'd be hurting yourself to target it | 21:00 |
| mhall119 | I don't know if anybody even still runs it on a phone | 21:01 |
| qtros | mhall119 no no, I mean desktop version of Ubuntu) | 21:01 |
| mhall119 | if you're only interested in targeting desktops, then there's a case to be made for using only the sdk-14.04 framework, but Ubuntu.Web isn't in it | 21:01 |
| mhall119 | qtros: you can run the stable desktop version and target Utopic in an emulator | 21:01 |
| mhall119 | that's still not 100% smooth, but it works | 21:02 |
| qtros | mhall119 but if I interested to target both, I should use 14.10 for now? | 21:02 |
| mhall119 | my "not smooth" I mean QtCreator won't recognize the newer API elements, so some of the help if offers won't work | 21:02 |
| mhall119 | qtros: if you use the sdk-14.10 framework, you'll only be able to target utopic and future releases, not trusty | 21:02 |
| mhall119 | that goes for phone and desktop | 21:03 |
| qtros | mhall119 I just want to write apps for UP and have ability to test them on desktop like before) | 21:04 |
| qtros | mhall119 is it possible on Utopic?) | 21:09 |
| mhall119 | only if you have Utopic on the desktop | 21:12 |
| mhall119 | if you have trusty on the desktop, you can only run your app locally if it's using the sdk-14.04 framework APIs | 21:12 |
| mhall119 | basically sdk-14.04 means "Trusty and above", sdk-14.10 means "Utopic and above" | 21:15 |
| mhall119 | so you can use an sdk-14.04 app in Utopic, but not an sdk-14.10 app in Trusty | 21:15 |
