Hi,
so i've got a working HTML widget with krpano inside, playing a .m4a sound file (compulsory for iBooks Author),
it's working fine, sound playing while Pano widget entering fullscreen,
but closing widget (with built-in arrow in left-top corner of the iBook) doesn't stop the sound...
any Work-around ? 
may be if there no user activity for a time, fade Out /Stop sound, and re-start sound on pano move ?
Thanks
z
can you provide a english link?
Thanx!
Tuur 
wooooow!! really thanks Zadda for the info and for the link to the website....i'm really happy!!
I have an ibook woking with an whole tour and audio thanx to Imge. But i suppose this is the way to go with the audio.
i don't see where to download a widget example.
And/or don't understand what to do at all.. 
should i put this in my index?
var starts=1;
var exists=0;
widget.pauseAudioVisual = function() {
exists++;
update();
};
widget.didEnterWidgetMode = function(x) {
starts++;
update();
};or elsewhere??

hi again zadda....sooo, i've managed to pause the audio when exit the widget and remaining in the same page click the widget again and restart the audio via sound interface and html audio tag.....the problem that i have is that if after the exit of the widget, close the page, and then open the same page again, the sound restarts without opening the widget, i mean the page is displayed with audio on...and if y click the widget, the audio restarts again....
i really don't know how to manage it , if y or someone else has a workaround please post it
imge

I could help, if you get me there.
But thanks for nothing.

Hi Guys,
it take me some times too to figure out,
here the working code :
in your html (should be main.html in your widget), in the <head> section :
<script type="text/javascript">
function update() {
//
};
// This function triggers when the user exits the widget.
// Widget can Returns to original state when the user exits the widget
widget.pauseAudioVisual = function() {
// Get the krpano HTML DOM Element
var krpano = document.getElementById("krpanoSWFObject");
// stop panorama sound
krpano.call("pause_sound"); // <action name="pause_sound"> in .xml
// panorama back to starting position
krpano.call("starting_point"); // <action name="starting_point"> in .xml
// panorama unloading to free memory
//krpano.call("unload_free_memory"); // <action name="unload_free_memory"> in .xml
update();
};
//Starts the effect when the user re-enters the widget
widget.didEnterWidgetMode = function(x) {
// Get the krpano HTML DOM Element
var krpano = document.getElementById("krpanoSWFObject");
// introduction move of panorama
krpano.call("intro_move"); // <action name="intro_move"> in .xml
// re-start panorama sound
krpano.call("resume_sound"); // <action name="resume_sound"> in .xml
update();
};
</script>
</head>
<body onload="update()">in your krpano.xml,
setup the actions :
<!-- pause sound and restore picto state -->
<action name="pause_sound">
pausesound(bgsnd);
set(plugin[snd].crop, 0|50|50|50);
</action>
<!-- resume sound and restore picto state -->
<action name="resume_sound">
resumesound(bgsnd);
set(plugin[snd].crop, 0|0|50|50);
</action>
<!-- unload while running in bkg -->
<action name="unload_free_memory">
wait(2);
krpano.unload();
krpano.remove();
</action>when i enable the Unload_free_memory, there a latency (2sec.) when you re-open the widget,
without it , it restart instantly, but i don't know how many paused widget (in the background) can handle iPad memory ,
in the example of a iBook portfolio when user visit (launch and pause) , let's say 30 panos...
sometimes the iBooks app crash, so for safety the unload method may avoid this at the price of a slow restart of the widget
may be Klaus can give a better answer/advice ?
by the way, there also a tips to avoid the flash initialization (white screen) before widget enter fullscreen :
About opening the HTML widgetDepending on how complicated your HTML Dashboard widget is, your readers may experience a flash during HTML initialization when they open the widget in iBooks. To avoid this flash, modify your Dashboard widget so it tells iBooks when to switch from displaying the Default.png file to displaying the running HTML widget.
Make these three modifications to add this optional feature:
Add a IBNotifiesOnReady item set to true in the Dashboard widget's info.plist file, so iBooks knows this Dashboard widget will tell it when to switch to displaying the running HTML widget:
<key>IBNotifiesOnReady</key>
<true/>
Set your Dashboard widget to load the Apple javascript library:
<script type="text/javascript" src="AppleClasses/AppleWidget.js"> </script>
Set your Dashboard widget to let iBooks know when the HTML initialization begins, and iBooks can switch from showing the Default.png file to displaying the running HTML widget by calling (in javascript):
widget.notifyContentIsReady()
Important: If you choose to modify your Dashboard widget to avoid the flash, be sure to do all three of the above steps. You must compete all of the steps for this to function properly.
but i don't know how to setup the : widget.notifyContentIsReady()
Klaus, any idea ?
hope you enjoy guys
