• How should i build my GUI in Qt ?

  - by Apollo

  I am wondering which way is the best to start building a GUI+SOFT in Qt. I am trying to build a sound media player based on a MVC pattern. Until now i have found 3 ways to do so. 1- Should I use a .ui file thanks to Qt designer, is it flexible enough ? 2- Should I use QML to make the design than integrate it to a C++ development ? 3- Should I just start from scratch and do it by hand without Qt Designer and using Qt library ? Thank you very much for your answers.

• Communicating from website to desktop application (not vice-versa)

  - by chakrit

  I am designing an application such that it will have to react to certain actions required by the website, mostly the same way Last.FM client does (if you have used one) The way Last.FM client works is that, it will register a custom protocol in Windows (lastfm://) and on their website, they use that protocol to trigger certain action on the player, e.g.: lastfm://artist//similarartists will actually direct any Last.FM client running to load up similar artists. I would like to do the same thing for my application. Is this a good idea? Is there any good alternatives to send a message from a website to a desktop client in this manner?

• Download a php-linked file in JavaScript

  - by fonix232

  I have a big problem. I've made a simple Google Chrome plugin (based on the old Youtube Video Downloader) but I have some problems with it. The first problem is that it won't pop up a new save window on click, but opens a new page with the video in the default Chrome player. The second is, that when the user clicks right click-save, they won't get the video name but a standardized name. Is there any way to make a file save dialog with a specified file save name?

• Jquery: How do I fire/play a sound file when I want?

  - by Sotkra

  I have some code that basically inflates a 'balloon' through 15 or so stages and then makes it pop at the 16th stage. (yes, images are changed). What I'm wondering now is if it's possible to use Jquery to play a sound file whenever I reach that 16th stage (or when whatever var reaches whatever value) - in other words...when I want. I've found several jquery sound plugins but they all create this player which I must then click for it to play the file. How do I skip that 'click' part so that the sound is just...directly/automatically played? http://www.sean-o.com/jquery/jmp3/ http://www.happyworm.com/jquery/jplayer/ All help is appreciated G.Campos

• Invoking browser on steaming media URLs

  - by Maven

  I have a dirt simple little function that launches the blackberry browser on a streaming media file in order to launch the built in media player. Everything works fine but there is this annoying dialog every time from the browser asking me if I want to save or open the file. My answer is always "open" the file so is there a way I can make it default and not bring up the dialog each time? The code I'm using to launch the browser // Get the default sessionBrowserSession browserSession = Browser.getDefaultSession(); // now launch the URL browserSession.displayPage(url); This is on blackberry OS 5.0 Thanks!

• PHP & AJAX SEO - For users with javascript and non javascript

  - by RussellHarrower

  So I understand this may come across as a open question, but I need away to solve this issue. I can either make the site do ajax request that load the body content, or I can have links that re-loads the whole page. I need the site to be SEO compliant, and I would really like the header to not re-load when the content changes, the reason is that we have a media player that plays live audio. Is there away that if Google BOT or someone without ajax enabled it does the site like normal href but if ajax or javascript allowed do it the ajax way.

• 3d / 2.5d game library for iphone and pc

  - by Aaron Qian

  I'm trying to make a 2d shooter game with 3d background. The player and enemies are essentially just quads with textures. The background will be simple 3d polygons with textures and some fog and light. Therefore, I don't need a really powerful 3d library. I tried Unity3D and Torque2D, but I don't like to use their GUI editors. I prefer to work with code. So, is there a cross platform (mainly windows and iPhone) 3d / 2.5d game library, commercial or open source? I assume it will be only limited to c, c++, and object-c due to apple's new ToS.

• How to set background image in Java?

  - by Dew

  I am developing a simple platform game using Java using BlueJ as the IDE. Right now I have player/enemy sprites, platforms and other items in the game drawn using polygons and simple shapes. Eventually I hope to replace them with actual images. For now I would like to know what is the simplest solution to setting an image (either URL or from local source) as the 'background' of my game window/canvas? I would appreciate it if it isn't something long or complex as my programming skills aren't very good and I want to keep my program as simple as possible. Kindly provide example codes with comments to elaborate on their function, and also if it's in its own class, how to call on relevant methods used by it on other classes. Thank you very much.

• Service for converting SWFs with ActionScript to Video (MPEG, AVI, or MOV)

  - by pcooley

  The SWF files generated by our application are a basic template that reference external resources (images, and textual data) that actionscript uses to fuel the display. Thus the SWF is responsible for the creative layout of the screen the flash player. It is the results of this actions script, images, and textual data that need to be converted to a video format. Is anyone familiar with an online service that would be able to convert such .swf files that our site generates to a video format (say .avi, .mpeg, .mov). Or an application? Note: A more common case might be the conversion of an embedded FLV to a video, but this is not our need

• playing incoming video stream

  - by mawia

  Hi! all, I am writing an application which is a kinda video streamer.The client is receiving a video stream using udp socket.Now as I am receiving the stream I want to play it simultaneous.It is different from playing local video file lying in your hard disk in which case it can be as simple as running the file using system("vlc filename").But here many issues are involved like there can be delay in receiving and player will have to wait for the incoming data.I have come to know about using vlc to run a video stream.Can you please elaborate the step for playing the stream using vlc.I am implementing my application in c++. EDIT: Can somebody give me some idea regarding VLC API which can be used to stream a given video to particular destination and receive that stream at other end play it. with regards, Mawia

• VB.NET: Force user to use the topmost form

  - by SiliconCelery

  I'm programming a Minesweeper clone in Visual Studio 2010, with VB.NET, as a Windows Form Application, and I'm having trouble with the Game Won and Game Lost forms. When I show those forms, I want the game form to still be visible, so that the player can see where the mines were, but I don't want the game form to be enabled until the Game Won or Game Lost form is closed. Exactly like Windows Minesweeper does when you win or lose. There aren't any obvious properties for this, as far as I can see, and I've had no luck Googling, I don't know what terms to search. Any help is appreciated, thanks.

• Missing on-screen keyboard for Flash/Flex web application on Android?

  - by HDave

  I have an enterprise Flex web application, served up over https, that runs fine on Flash player 10.0 and beyond from a desktop computer/browser. However, when I run it from my HTC Incredible with Android 2.2 the app loads fine, but there is no on-screen keyboard and so I cannot log in. I can see the blinking cursor inside the username and password text fields. I can switch between them. I can even hit the login button and see an authentication error! According to Adobe this should Just Work. Any ideas? I wanna show off our spanking new app to strangers at the bus stop!

• Is it possible to access raw iphone audio output?

  - by Peter Hall

  Is it possible access raw PCM data from the iphone audio output? I know I can embed an MP3 and use AudioUnit. But if the user is playing music in the background from their itunes library, is it possible to access that audio data? This is for an app that shows visual effects, which react to the music. From what I can tell, it isn't possible, but that's just from lack of finding any information at all, rather than actual confirmation that it can't be done. If it isn't possible to access the audio stream from the ipod, is it possible to access raw audio output from the Media Player inside an app, or is pretty much not permitted to access raw audio data from the itunes library at all? EDIT: I found this question: iOS - Access output audio from background program, which say I can't access the audio from a background app. But is it possible to get the audio data from the itunes library if I play it inside the app?

• Playground for Artificial Intelligence?

  - by Dolph Mathews

  In school, one of my professors had created a 3D game (not just an engine), where all the players were entirely AI-controlled, and it was our assignment to program the AI of a single player. We were basically provided an API to interact with the game world. Our AI implementations were then dropped into the game together, and we watched as our programs went to battle against each other. It was like robot soccer, but virtual, and with lots of big guns. I'm now looking for anything similar (and open source) to play with. (Preferably in Java, but I'm open to any language.) I'm not looking for a game engine, or a framework... I'm looking for a complete game that simply lacks AI code... preferably set up for this kind of exercise. Suggestions?

• How to stream a WAV file?

  - by jonasb

  I'm writing an app where I record audio and upload the audio file over the web. In order to speed up the upload I want to start uploading before I've finished recording. The file I'm creating is a WAV file. My plan was to use multiple data chunks. So instead of the normal encoding (RIFF, fmt , data) I’m using (RIFF, fmt , data, data, ..., data). The first issue is that the RIFF header wants the total length of the whole file, but that is of course not known when streaming the audio (I’m now using an arbitrary number). The other problem is that I'm not sure if it's valid since Audacity doesn't recognise the file, and Windows Media Player opens the file but plays only a very small part. I've been reading WAV specs but haven’t found an answer. Any suggestions?

Hope somebody can show me some tips, maybe sample code :) Any suggestion are welcome~

• Can FLV AAC stream be played in Android

  - by HariKJ

  Hi, I'm trying to build a radio player and the client is providing a stream which is a FLV container with the audio being AAC When I read the headers it shows up as audio/aacp. I have tried all possible ways such as using the 1) Streaming through mediaplayer (Does not work) 2) Use the NPR mode of using a proxy stream (I get a broken pipe exception) 3) Play it in chunks ( Plays but I need the SDCard and the playback is not very great) 4) Use the GPL'd FAAD2 Library but I would have to pay the royalty fee Can some one help me out on figuring this issue out. The last option that I have is to have my client change the stream to mp3 container (which I know that it works) Regards, Hari

• Creating Ruby applications for Windows.

  - by Omega

  I want to develop a Windows application. Honestly I care little about cross-platforms for now (but still would be good) I want to use Ruby, since it has quite a simple syntax and is so.. well, simple and easy to learn. My application is like a "game level creator", where you can design your own level and then run it with another application which is a "game level player" by reading the project file created by the creator app. You get the idea. Now, I got a new PC and is completely clean. Absolutely no trace of my old Ruby experiments and fails. First of all, I will need to choose a GUI platform for my Ruby application! Can you recommend me one? I have heard of Shoes and Tk, but want to know what you think.

• C++: Create abstract class with abstract method and override the method in a subclass

  - by Martijn Courteaux

  Hi, How to create in C++ an abstract class with some abstract methods that I want to override in a subclass? How should the .h file look? Is there a .cpp, if so how should it look? In Java it would look like this: abstract class GameObject { public abstract void update(); public abstract void paint(Graphics g); } class Player extends GameObject { @Override public void update() { // ... } @Override public void paint(Graphics g) { // ... } } // In my game loop: for (int i = 0; i < objects.size(); i++) { objects.get(i).update(); } for (int i = 0; i < objects.size(); i++) { objects.get(i).paint(g); } Translating this code to C++ is enough for me.
