Hi people

This is my 1st post on here, have used this site many times before to help me out but i can’t find anything on what I’m trying to do now.
I’ve used the rotary wheel scripts before just by altering a prewritten script, i was wondering if anyone would be kind enough to help me out?

I’m using PEP2 and need a simple time out script on a page load. E.g. A button is linked to a favourites page and after 30 seconds of inactivity on that page it then executes the command 'browse back' to return to the previous page

Any help would be great thanks

Regards Chris

I'm not sure I understand you correctly, but.

Assign the browse backward to the back hardbutton.

then:
var inactivity = true;

page().onEntry = function () {
scheduleAfter(30 * 1000, checkInactivity);
}

function checkInactivity() {
if (inactivity) CF.widget(PS_BACK).scheduleActions();
}

This will start a wait of 30s after the page is loaded. If nothing happens during these 30 secs. the the remote will go to the previous page. I don't know what you do with that button, but if you add:

thebutton.onPress = function () {
whatever it has to do;
inactivity = false;
}

Then if you execute the keypress, the remote won't browse backward any more.

That looks like what im after... only only problem is that the browse backward is a virtual button on a hidden page, how do i ammend the script to trigger a virtual button?
sorry for the noob questions but would like to get this done.
oh and thanks for your speedy reply

Virtual you mean dynamic widget or just a on screen button?

If it's a classic button widget, select the button and for the action select Jump ... Browse backward. Give it a TAG (Name, not Label) and then

CF.widget("BACK_BUTTON_TAG",button page, button activity).scheduleActions().

Not noob questions, we all had to get to know this stuff somewhere in our past.

Its a touch screen button, one you can press.
ive now got;


var inactivity = true;

page().onEntry = function () {
scheduleAfter(10 * 1000, checkInactivity);
}

function checkInactivity() {
if (inactivity) CF.widget(back, hidden, Sky Favourites).scheduleActions();
}


still no joy tho :(

I amended the 30 * 1000 in the script, i guessed by changing it to 10 it will give me 10 secs before it executes?

also I entered this in the activities script page, does it belong in here or on the page properties script?

many thanks

you should put this, wait...

EDIT:

Here is a simple xcf with the stuff: -> [Link: dl.dropbox.com]


Just to let you know. You don't need to put the backward action on a button on the hidden page, you can pin it also to a macro (the category above the pages) and execute with:
CF.widget("MY_MACRO", "SOME_MACROS", "PS_MACROS").scheduleAfter();

Yes, the first number in the scheduleAfter is the amount of seconds it waits.

did you just knock that up for me!?

I can work out the rest from here, thank you very much for all your help you have been so helpful

All the best
Chris

No problem. Enjoy your pronto!

I've put it on my project and its all working fine, BluPhenix you are the man!
but just a another question...
the page will work 100% but im thinking... is there a way where if you tap any key (make the control active) the ''timer'' will reset back to 10 seconds again because at the mo the page only stays on for 10 seconds then does the ''browse backward'' command, it does this even when your tapping the keys to keep it active, any idea why it does this???

Maybe he left that as an exercise for the user? Not sure.

i get the hint :)
cheers guys

No idea if that is the case.

Several things that may help.

1. You cannot cancel a timer once started.
2. You can start subsequent timer.
3. You can use 'user data' such as sequence number to pass along with a timer. User data will be used as parameter to function when timer is called.
4. This user data can be a sequence number in stored in a variable for later reference.


// In activity script
var currSeqNum = 0;
function myTimerFunction(seqAtTimeOfTrigger)
{
if (currSeqNum === seqAtTimeOfTrigger)
{
// do something as user has not reset/restarted timer.
// jump back.
}
}

function setupOrRestartTimer()
{
currSeqNum = currSeqNum + 1;
CF.activity().scheduleAfter(10*1000, myTimerFunction, currSeqNum);
}


In each of your onscreen buttons that need to reset the timer, you will need to add prontoscript.


// Button Script
setupOrRestartTimer();
this.executeActions();


In the page script where you need to start the timer, you will need to add prontoscript.


// Page
setupOrRestartTimer();


Note that you can take this farther and use only a single active timer by keeping track of time remaining before JumpBack must occur. This is the more resource-friendly approach as there are only 64 allowed timers. That is, if you have a long timeout period and user presses 65 buttons, that 65th press will fail to start a timer and you will then lose JumpBack capability because timers 1 to 64 above will not act because sequence number does not match.

I leave this as an exercise for you to experiment with.

Philips did something like this in the RS232 scripts for Denon/Marantz receivers. Admittedly, their code is rather complicated and sometimes difficult to read but it does the job.
