I have a technical doubt on an ePub3 job and thought of checking with you all and get your understanding and advise on it.
For one of my German client, I have created a ePub 3.0 re-flow with interactivity, we have used all the interactivities to work on pop-ups (Non-linear content) and it works well on iPad iBooks 3.2, as the initial request from client is to work only for iPad.
I understand that a latest Apple spec (iBooksAssetGuide 5.1 Rev 2) now says that “Develop scripts that perform well on both Mac OS and iOS devices: Interactivity on desktop computers requires input from a mouse while interactivity on iOS devices require touch input”. I’m not sure whether there would be any problem while this job goes into the Apple iBooksstore, due to the latest spec.
It would be of great help, if you all please share your idea’s / view to this problem.
Regards,
John.A
Great question. With the latest version of OSX (Mavericks) running iBooks as well, there are a few things that need to be considered when using touch interactivity in ePub3 books. The most important (and relevant here) of these is making sure you are firing mouse events as well as touch events: because they behave differently.
The most robust solution that I have found to date is using JQuery or Quo's "tap" event: as it will fire with both touch and mouse events! However, if your code digs deeper (IE if you you use events like "touchstart", "touchmove", etc.) you will need to use the corresponding mouse events to insure functionality on the desktop.
Tap.js is a great little library for stuff like this: http://alxgbsn.co.uk/2012/03/12/tap-js-a-lightweight-tap-event-javascript-plugin/.
You should also be aware that iBooks for OSX behaves differently for many features (especially when it comes to external media content and dynamic loading of content), so you should never rely on OSX only when testing...
Good luck!

I have been trying to build a TV application, using an SD.
I have got features like image gallery, video player running,
However, I also wanted to add a virtual on-screen keyboard that works with up-down left-right arrow keys. Can somebody help me with how to get started?
When I wanted to do this with my Vestel (Polaroid Branded) smart TV, which uses "Opera for TV devices" as it's HbbTV browser, I found that I didn't need to.
I simply just used HTML text fields and input types where needed, and as soon as I clicked into them, the browser/OS kernel popped up an onscreen keyboard that was built in for me.
However, I did do some research to see if I needed it, and on some devices you do, whilst I never actually implemented it (My app was just for my own use) the "BBC Television Application Layer" (TAL for short) : https://github.com/bbc/tal had pretty good keyboard support.
Another one that might be worth looking at is "Mautilus SDK" : https://github.com/mautilus/sdk
Be aware though, both are horribly convoluted and use quite complex code where it's really not needed.
When trying to use barcode scanner in bad lighting conditions, it would be very beneficial if possible to light the LED/Flash that comes with the phone/tablet
I have found out that the ZXing library that is used by the ngCordova BarcodeScanner automatically supports this feature (although it is not yet documented). The source code states that if you click the volume up button then the LED/Flash if present will be lit up. Clicking the volume down button will turn off the LED/Flash.
Although I can not be 100% certain, but given the life of ZXing library for CaptureActivity I think that any barcodescanner using it will be able to use this functionality assuming a flash is present.
Hope this helps someone.
I want to create a desktop mockup on Elementary OS 0.2. By "mockup" I mean something that shows off the aesthetic of the mockup, mostly just showing what selecting/clicking/hovering over a button or widget does to that particular part of the UI. I'm thinking about creating the various parts on GIMP and coding animation and transition logic into the final result. I know that something like this can be done in HTML/JS, but I want to avoid using those. Is there anything optimized for a project like this? I'm open to most languages.
Try WireframeSketcher wireframing tool. Unlike Gimp or PowerPoint, WireframeSketcher is designed specifically to help you create mockups and wireframes. It comes pre-packaged for Debian systems and can also be found in Software Center and so it works on Elementary OS too. Note that it's a commercial tool, but you can try it freely for 14 days.
Most PMs at large companies mock these things up using a presentation package like PowerPoint. If you know the routine and where to click it can look fantastic with minimal effort.
MockupUI does both wireframe and Windows native looking mockups. It uses your desktop's visual style which makes screens and widgets look as a standard Windows application. MockupUI lets you export screens as individual images, docx, pdf or html.
Actions/interactions can be explained by highlighting widgets and adding text annotations.
This question is related to: Which API Microsoft Word (Office 2013) is using the paint the screen, which was left unanswered.
I have an Office plug-in (native C++) which is fairly involving with Office. Using hooks I'm modifying the client area of Office application.
Things were working great for me up to Office 2010, hooking WM_NCPAINT, and using GDI method on the Office Window.
But Office 2013 uses Direct2D, DXGI, and DirectWrite. On Windows 7, if I draw something on the screen - it gets erased the next time the cursor blink. On Windows 8 - I don't even have access to the screen.
Currently, my thinking is to hook ID2D1DeviceContext::BeginDraw, ID2D1DeviceContext::EndDraw - and on last function, just before delegating to the real function, I will add my stuff. Another idea is the hook IDXGISwapChain1::Present1. Problem with both these methods that I've hard time identifying what is going on above.
I'm even thinking even a different process (or GDI based window - if possible) on top of the client area I want to decorate, with the majority of the real eastate being 100% transparent. Problem with this solution are issues like keyboard focus and mouse click.
Any tip or suggestion will be appreciated. Any tool (the Spy++ for DirectX) will be appreciated. Does DirectX (specifically Direct2D) has documented extensible or plug-able story, I'm not aware of and could use? Is there anything in Kernel Mode I'm missing?
Hm dont know exactly how that works on Direct Draw, but i hooked once the EndScene function for Direct3D and added some stuff to the scene before the real EndScene could be executed.
I made a little video that shows that:
http://www.youtube.com/watch?v=ZFshqIEaLBc
Here's my advice: don't do that. Any of it. If you find yourself having to hook and hack into the host that deeply, it's a clear sign that you just shouldn't be doing that. Find another way to draw what you need, or change your UI design so that it fits in with what Office already accomodates. Even if you assume it's possible to get this working, every time Office is updated (patch, service pack, new version) you will be at high risk of all your stuff breaking, with no guarantee that you'll be able to get it working again.
Recently I have a problem with playing my soundeffects using CocosDenshion. The sound is playing on the iPhone Simulator, but not on my own device. I am not sure what I am doing wrong. Off course I checked if my speakers are still working, but they do while using other apps or the iPod Library.
I just use this simple code:
[[SimpleAudioEngine sharedEngine] playEffect:#"button.wav"];
I double checked the name of the file and it indeed is button.wav.
I hope someone can help me out.
I had the same problem recently and I've figured it out.
I' m using Xcode 4.3.2 and there seems to be a bug.
Not all resources you add (drag) to the project are by default added to the target.
When you add a resource, make sure that (apart from checking the copy items into destination checkbox) you also check the add to target checkbox.
You can check if the resources has been added to the bundle by clicking on the target icon. In the Build Phases tab, check if the sound files are included in the Copy Bundle Resources.
If not, add them manually (+add target)
You might try preloading the sound effects, at some earlier point in the program, as otherwise it has to load the sound effect before it can play it. You could create a splashScreen scene that is the first scene and loads all your assets and then transitions to the first "actual" scene.
SimpleAudioEngine *engine = [SimpleAudioEngine sharedEngine];
[engine preloadEffect:#"Example-Sound.caf"];
Not sure whether it is the case here, but you should keep in mind that if your file name is "Button.wav" and you are asking to playEffect:#"button.wav" it will play on simulator, but will not on the device. This effect takes place because filesystem on your desktop is case-insensative, and on iOS devices it is not.
I have the same problem and find here. But I fix it by myself.
If you reinstall ios for ipad. the default switch(upon the volume) is default as "mute volume" method. Maybe I change it to "rotation" method when it is mute. It lead to all cocos2d can't play sound any more. So I turn the method back and set mute off. And then SimpleAudioEngine works well. It is ios system's bug.
Make sure to check your audio file itself. A Mono 16 Bit, Uncompressed wave with a sample rate of 441000 should 'just work'. I recommend grabbing a sample .wav from an online Cocos2D example, like the Cowbell.wav and try to play that file.
