[03:58] hey guys I have a problem with QT 5.4 qml sample HelloWorld [03:59] http://pastebin.com/fEmAPcdK [03:59] the menu items only show once [03:59] can't bring them up again [04:00] learner, hey [04:00] let me take a look [04:00] thanks [04:01] learner, btw; what are you developing for / with? [04:01] learner, The ubuntu sdk is an ide for both qml, qt, and c++ [04:01] Qt creator that came with Qt 5.4 [04:02] learner, are you on linux? [04:02] I'm just learning qt after a few years of not having used it [04:02] last time i used it it was 2004 [04:02] learner, ah cool [04:02] yes i'm on ubuntu [04:02] learner, did you learn c++? [04:02] learner, ah great! [04:02] learner, for a better hello world example, download the ubuntu SDK [04:03] Ubuntu uses QML by default now, so I think its templates are more developed than Qt's QtQuick ones. [04:03] yes AkivaAvraham I used to use qt all the time till 2004, then i started working with ada and primarily developed with ada so I haven't used it for a long time and a lot has changed [04:03] learner, so then you understand all the ins and outs of c++, memory management, and all that jazz? [04:04] ok that's lovely, I just want to know why these menu items are behaving this way, and i'm more than willing to use another development ide [04:04] yes AkivaAvraham [04:04] learner, its the same ide, but with ubuntu plugins [04:04] ok do i apt-get install them? [04:04] :) The only reason I asked, is that there is a great manual for teaching c++ and QT at the same time. I recomend it to newbies, of which you are not :D [04:04] yah sorry ! lol, leg me grab it for you [04:05] are you on 14.04? [04:05] yes [04:05] okay cool beans [04:05] learner, sudo add-apt-repository ppa:ubuntu-sdk-team/ppa [04:06] learner, sudo apt-get update && sudo apt-get install ubuntu-sdk [04:06] That should be it. Alternatively, you could grab 15.04, or 14.10, but you'll need the ppa still [04:06] erm, I think [04:07] learner, also the great thing about the ubuntu sdk, is that we have testing built in, that you can program in python [04:07] i'd rather stay on 14.04 until 16.04 comes if possible\ [04:07] learner, +1 :D [04:08] okay ping me when you got that jazz all ready [04:08] will do thanks AkivaAvraham [04:34] !ping [04:34] pong! [04:36] AkivaAvraham, it's done installing [04:37] okay [04:37] learner, i'm on low battery, but i'll be back on in 40 minutes or so. [04:38] ok np [04:38] alright so lets start [04:38] learner, create a new template [04:38] choose from one of the ubuntu options. [04:39] learner, there are two types of templates, and one of them is handled by CMake, which allows you to use Qt and C++. [04:39] If you are planning pure qml though; that isn't neccessary. [04:40] no i'm doing a c++ project [04:41] going to write a webserver + web contents + APIs [04:41] learner,but you want QML though, right? [04:41] yes [04:41] okay then [04:41] one sec [04:41] I want multiple representations [04:42] so i'll have these interfaces that will be implemented differently [04:42] the web interfaces will display using html, and desktop/mobile interfaces using qml [04:42] learner, okay, go new file or project > Ubuntu > "App with QML Extension Library" [04:43] learner, well you can program this in html5 btw [04:43] one sec, it's still building ubuntu env [04:43] oh? [04:43] what about the server? [04:43] although I'm not an html5 guy. [04:43] i'd rather use c++ wherever possible [04:43] learner, i'm the wrong guy to ask [04:43] it's a more solid ground for me [04:43] Alrighty~ [04:44] i've done python too, and i'm tired of django, and the whole bs of tiny projects that don't work in different versions [04:44] also I will be using BDD [04:44] For QML, and Qt, the only things that you may need to know, beyond getting used to the extremely wonderful qt library [04:45] are the preprocessor macros that allow you to inteface [04:45] ok, have they changed a lot? [04:45] i'm guessing they have [04:45] learner, no clue, but the template will handle it for you [04:46] the only one you will be writing yourself is probably Q_INVOKABLE [04:46] ie, you can "Invoke" the c++ function in qml [04:47] ok some sort of IoC then [04:47] learner, oh btw; because you are using this library, there is a good chance that this app will just work on ubuntu phone. [04:48] wouldnt that be cool :) [04:48] that'd be a lovely plus [04:48] i'd be happy if it'd work on android as well [04:48] will make my life much easier [04:49] I think i'll develop the windows and mac versions using html5 [04:49] learner, for debugging, #include and and use qDebug() << stuff; [04:49] but if i can do the android and linux versions using qt creator and cpp i'd die a happy man [04:49] is there a BDD for Qt as well [04:50] BDD? [04:50] behavior driven development aka gherkin [04:50] like igloo [04:50] Probably, but I don't know. [04:51] learner, oh you mean for testing? [04:51] yes [04:51] TDD/BDD [04:51] learner, yah ubuntu touch has something called autopilot3 [04:51] you write the tests in python, [04:51] ok [04:51] it comes bundled with the projects [04:52] it uses pyqt? [04:52] learner, no; just python afaik. [04:52] ok [04:52] good [04:52] cause i hear bad things about pyqt [04:52] it has memory leak problems [04:52] learner, it will do things like, "Move mouse to this button, click it" [04:52] nice [04:53] something like selenium [04:53] learner, ive decided that python is not a programming language for me :) Scripting, yes, but I am actually more inclined to use qml these days to write quick apps. [04:54] AkivaAvraham, yeah i don't like interpreted languages anymore [04:54] i've done ruby, perl, and python [04:54] it's very shaky [04:55] learner, python was a good starting language though. [04:55] and the break of py2 to py3 really messed me up [04:55] i have apps on django, that i can't test anymore [04:55] learner, them intentionally breaking print was... why? [04:55] cause the TDD/BDD app, lettuce, only supports python 2.6 and 2.7 [04:55] and django 1.72 is py3 only [04:55] It really is remarkeable how python3 is still in limbo [04:56] yeah [04:56] they didn't have a good roadmap [04:56] like i like py3 and all [04:56] but it's kinda like they didn't have a good idea what they were gonna do to shift apps up [04:57] and you have these tiny agile project that release minor changes that end up being huge changes every 2 weeks [04:57] learner, yep. [04:57] and then all of a sudden one project using one tiny version another, another [04:57] and you get into library hell [04:57] learner, although I must say, my favourite web app was powered by python. [04:58] you can't use this module cause it becomes incompatible with that one [04:58] Heh. [04:58] working on python for me, is playing counterstrike [04:58] learner, oh btw, ubuntu has a new packaging type. [04:58] you're getting shot at from left and right [04:59] oh? [04:59] do tell [04:59] learner, yah it is called Click Packages. [04:59] They are standalone, and they created them because they tried with deb [04:59] but as I understand it, could not get it to have the security features they desired [05:00] so with click, they are basically standalone. [05:01] so if I want to execute python code, I need to bundle an interpreter in my code [05:01] So very good on security :) [05:03] so you have full sandboxing? [05:04] learner, ah that is the proper term; thanks [05:04] learner, they use apparmor, so you give yourself permissions [05:04] learner, and while using the phone, say if something wants access to your personal info, afaik, it prompts you on the fly [05:04] they should probably use fail2ban, apparmor and jail [05:05] instead of being like android, where you install, and just accept all the permissions. [05:05] well android really is made for google to steal your data [05:05] we all know that [05:05] unfortunately users don't [05:06] learner, I was really dissapointed by android. [05:06] The Java Virtual machine... it just does not cut it. I wanted Linux [05:06] Thats why I am excited for ubuntu touch. [05:08] yeah but when you develop apps you need to cater to users, not to wht you feel is right [05:08] if it were up to me, i'd get rid of all windows, android, and ios machines [05:08] and only allow linux [05:08] or bsd [05:08] and nothing else [05:08] and ban google.com [05:08] learner, to each his own. I may not make any money doing what I do, but doing what you love is rarely that easy :) [05:09] learner, anyways let me get back to what I was working on. ping me when you need a synopsis of qml [05:10] will do [05:10] still waiting for the dev kits to set up [05:10] learner, oh and in qtcreator, for docs, click on a class or object, bring up the hud, and type "context help" [05:10] it seems to be slower than the installation [05:10] ok i'll do that [05:10] learner, are you building from source? [05:11] it seems to be [05:11] :? [05:11] i just clicked on create a dev kit [05:11] ohh [05:11] that [05:11] and selected amd64 [05:11] okay [05:11] yah thats for your build environment. [05:11] but it's doing compilations it seems [05:11] learner, yah that takes awhile [05:12] touch is amd64 too? [05:12] learner, so if you had a phone that had arm, and you wanted to test the app, you would select arm, build it, and run it on the phoen. [05:12] or do i need another environment dev kit for that [05:12] learner, it depends on the device [05:12] ok [05:13] learner, so you can also build emulators in this, its based on the android emulator. [05:13] so your probably familiar with it. [05:13] adb [05:13] thats it [05:17] i can't wait to start working on this [05:17] thanks a lot for the help [05:17] learner, :) [05:17] learner, QML is one of my favourite languages. So straight forward [05:18] it's very much like angular.js [05:18] learner, although nothing is better than gnu-apl [05:18] lol [05:18] i haven't done much of that, i'll have to take your word for it [05:18] learner, btw, when you start creating your app and you have some screenshots, would you mind posting it to our subreddit? [05:19] sure [05:19] http://www.reddit.com/r/ubuntuappdev [05:19] learner, have you had the chance to try ubuntu touch on a tablet or phone? [05:19] not yet [05:20] learner, have you seen it? [05:20] i'm ordering a fujitsu tablet next month, gonna install it on that [05:20] i've seen vids / screen shots [05:20] not used it nope [05:20] learner, I tried it for 45 minutes, and after when I switched back to android, I kept instinctively trying to side swipe [05:20] to launch apps. [05:21] at that point I knew that Ubuntu had created something really wonderful. [05:21] well ubuntu has a lot of smart people behind it, making smart choices [05:21] :) [05:21] one thing i really got upset about was the drop of the old gnome though [05:22] a lot of people use xfce nowadays for the feel of gnome 2 [05:22] learner, not me; I love unity7 because of the hud. [05:22] it is incredibly useful [05:22] i kinda have 3 different desktops now, unity, kde and xfce [05:23] learner, in fact, I am developing my plugin for qtcreator to utilize the hud, so you can just type the test you want to run, and go. [05:23] for a dev like me, i like a clean desktop with capability of a 4x4 wall / cube [05:23] to quickly swich and rotate [05:23] s/swich/switch/ [05:23] learner, woah you still use the cube XD [05:23] yeah :P [05:24] learner, compiz is still really great. [05:26] yep [05:26] i still have a few desktops with terminal hardcoded in [05:26] learner, do you use the hud at all in unity? [05:26] so like it has nothing but a terminal in the background loaded in [05:26] I think that is a feature most people overlook. [05:27] i use it to launch apps sometimes [05:27] learner, thats the dash [05:27] learner, the hud is different [05:27] the hud lets you launch menu commands [05:27] no that's the one i use [05:27] you type in what app you want [05:28] or like search for files [05:28] learner, no thats the dash XD [05:28] ok maybe [05:28] press left alt [05:28] not super [05:28] learner, its really useful in Gimp which has hundreds of menu items [05:29] cool [05:29] or for menu commands which don't have keyboard shortcuts. [05:29] i don't use gimp, i use photoshop but i get the point [05:29] :O [05:29] learner, ive never used photoshop [05:29] learner, can you tell me if it is actually that much more advanced than gimp? [05:30] in terms of raster design yes [05:30] hmmmm [05:30] learner, you know photoshop can run on linux now, right? [05:30] in terms of use of bezier curves it's much easier to use than gimp [05:30] learner, they stream it in on chromebooks [05:31] without wine? [05:31] Yah [05:31] its bewildering [05:31] I can only imagine how much of a mess their code base must be when it is easier to stream the application in, rather than just develop a port. [05:32] well photoshop's base is QT [05:32] you know that of course [05:32] learner, no; i'm shocked actually [05:32] Now I'm even more surprised. [05:32] the main functionalities like the Gaussian calculations they're all simple c++ libs [05:33] so less than 5% of photoshop is really machine dependent [05:33] the rest is very easy to port [05:33] almost all of its ui is fully portable to any machine [05:33] learner, why don't they then just port it to linux? [05:34] AkivaAvraham, money! [05:34] waht? [05:34] okay i'm sure theres a reason. [05:34] they want to sell photoshop licenses for huge amounts of money [05:35] if they started providing photoshop on linux, then they wouldn't be able to charge those huge amounts anymore [05:36] you know the story of macromedia right [05:36] how adobe bought them [05:36] learner, maybe. Nope. [05:36] do tell [05:36] oh wise and vetted one :) [05:36] macromedia was a much much better software company than adobe [05:36] lmao [05:37] adobe only had one project that sold a lot [05:37] photoshop [05:37] the rest of its apps were mediocre [05:38] illustrator was soo much worse than freehand they literally copying freehand [05:38] ha [05:38] dreamweaver [05:38] flash [05:38] fireworks [05:39] all of these are macromedia inventions [05:39] then all of a sudden, adobe buys macromedia [05:39] why? because they had billions of bucks lying around from photoshop [05:40] then all of a sudden illustrator becomes great [05:40] ha [05:40] it starts becoming better than corel draw even [05:40] why, cause they basically dropped the illustrator engine and used the freehand one instead [05:40] learner, just curious, you know gimp finally has a unified interface right? No more 3 window if you don't want it. [05:41] I used it with a tablet, it was actually really nice to use with a stylus [05:41] well that's good, but the problem with gimp isn't just wth the ui [05:41] although I don't use gimp for much. [05:41] well that was a huge problem [05:41] * AkivaAvraham hated the three window ui [05:42] gimp isn't UX driven [05:42] meaning they don't sit and think hmm, how would a designer wanna use gimp [05:42] Unix? [05:42] user experience aka ux [05:42] interesting [05:42] learner, I honestly think though the Gimp and the HUD, is such a killer combination. [05:43] AkivaAvraham, you're not a painter are you? [05:43] I think photoshop has that as well of course [05:43] learner, exactly [05:43] a tablet user, don't want lots of menus [05:43] they don't want to type for a command and bring it up [05:43] they want button combos [05:43] learner, well that is what the hud does. [05:44] type for a command, and there it is [05:44] a designer using wacom 24 hd touch [05:44] they will have a wheel and a few buttons [05:44] they'll map them to a set of things [05:44] and that's what they'll use [05:45] the only time they use the keyboard is when naming groups, layers, or smart objects [05:46] * AkivaAvraham gets back to work === chihchun_afk is now known as chihchun [10:13] hei, don't .click packaging work on ubuntu desktop? [10:22] Ashik, not *yet* [10:23] Ashik, they seem to work on vivid unity8 preview, but I cannot ensure you how much [10:29] ok, thanks. [11:03] mzanetti: hi, when you around and have time, see the currency-prop-1.png in the drive and let me know which one you like if any :) [12:15] .click is for the next version of ubuntu, it's not implemented yet [12:15] even the design isn't finalized [12:15] don't use it yet [12:17] really? i thought it was mature enough that the myapps stuff was all supposed to be self-packaged using click already [12:26] i don't think so, not from what i've read [12:27] i really hope it becomes standard soon though, the whole sandboxing thing is very intriguing [14:11] Hooray! Just had my app approved and published. Thanks for the help everyone! :) [14:14] mzanetti: hey, I had problems with my internet earlier, so I'm not sure if you have answered about the currency symbol or not :) [14:15] mivoligo1: hi. no, didn't reply as I saw you going offline [14:15] ah ok [14:15] so what you think then? [14:15] mivoligo1: I've talked with some people and they seem to agree that instead we should show a coin [14:15] mivoligo1: not sure how that works color-wise though [14:16] what do you think? [14:16] from your proposals I think I like the first one the most [14:16] mzanetti: by a coin you mean a circle with something inside I guess [14:17] yes [14:17] well, dunno, just an idea... [14:17] mivoligo1: I've pushed a bunch of sounds :) [14:18] mzanetti: did you downgrade the required components as well? :P [14:18] arh right. let me do that [14:19] thanks [14:19] mzanetti: I tried running the game on 14.10 in virtualbox and it's painfully slow [14:20] hmm.. [14:21] well, pushed the downgrades [14:21] mzanetti: I guess my computer is not really up to speed [14:22] I still need to do another round of optimisations though. [14:22] while it still works on the phone, it's reaching the limits [14:30] mzanetti: about this bug with the stars: the svg file for them uses blur but in the game it'll be lost [14:32] oh, I see [14:32] mzanetti: so I may redesign them a little [14:33] mivoligo1: whatever you think is better [14:33] we can also keep the current ones... [14:33] I just noticed it right now as I way paying attention to properly scaling all the icons [14:36] mivoligo1: now I only need to finish the last 4 levels, create the new tower info dialog and then I think we're set. anything else missing? [14:37] mzanetti: what about the levelpack creation tutorial? [14:37] that would be a website I'd say [14:38] ok [14:39] mzanetti: I've seen some testing going on in the drive, what the guys think? [14:40] feedback was quite good so far [14:41] I'd give them some more time to complete more levels . mainly I want to find out if there are some levels too easy [14:43] ok :) [14:46] mivoligo1: can you edit InfoPage.qml and enable line 66 and 69? [14:46] mzanetti: see the coin-1 in the drive, something like this or more real? [14:46] * mzanetti looks [14:47] hmm... looks quite nice [14:47] lets see how it looks in the game [14:48] mzanetti: colour can be reversed of course [14:49] mivoligo1: would look great in the panel I think. not sure what to do in the price tags of the towers though [14:53] mzanetti: can we have to version? or should I make it like golden or something? [14:53] s/to/two [14:54] I don't think in the panel it would look good with another color. needs to be white on black [14:54] It probably would work for the price tags, but my main concern there is space [14:55] I guess in there we sould just have the M [15:01] mzanetti: you mean just the letter M or that fancy sign? [15:03] mivoligo1: the fancy sign [15:05] mzanetti: what about the tower info? There we need the dark one :D [15:06] mivoligo1: yep. we can also have the coin there as there's enough space [15:07] mivoligo1: hmm. I can't see the price any more in the new tower info dialog [15:07] mzanetti: so we need one white coin, one black coin, one white M sign right? [15:08] mzanetti: it wasn't finished :P [15:08] ah ok. thought you dropped that intentionally [15:08] we might have a problem with vertical space on the phone there then [15:08] if it doesn't work out I'll do the two-column thing again like it is atm [15:09] mzanetti: I was thinking if we can put price on the tower icon [15:09] ah, nice one [15:09] yep, works for me [15:09] but might be a little tight if the tower is locked [15:10] true [15:11] mzanetti: let me try a mockup [15:13] mivoligo1: hmm... the current code makes it a bit nasty to show both... (not that its impossible, but the component is quite generic and doesn't support it atm) [15:13] so if it's not a must have I'd like not to mess with that any more [15:13] OK [15:14] we could just not show it if locked (which is what the component does atm) [15:14] mzanetti: so go with 2 columns for now [15:14] or do the two column thing, yeah [15:14] well, I'll implement something and then we can have look [15:14] great [15:15] mzanetti: I thing a player could plan ahead if she knows the price of upgrades and stuff fro that dialog [15:16] yeah.. [15:17] mzanetti: do you have "release" date already planned? ;) [15:17] nope [15:18] doing another teaser? :D [15:18]
