Trying to figure this out

Hi Padley,

I modified the first stack I posted so that images in the horizontal scroller scroll into view after scrolling. That way you have one image centered at a time.
Should be generic enough for other/more pictures.


Kind regards
Bernd

Edit: I tested it on my iPhone G3 and the snapping to the image after scrolling was a little too slow.
To speed that up you can increase the stepsize in the repeat loop to 10 in the card script in the "findNearest" handler

Code: Select all

      repeat with i = tCurrentLoc  to tClose step 10 -- change stepsize
         set the hScroll of group "picGroup" to i
         wait 5 milliseconds with messages
      end repeat
   else
      repeat with i =  tCurrentLoc down to tClose step - 10 -- change stepsize
         set the hScroll of group "picGroup" to i
         wait 5 milliseconds with messages
      end repeat

Wow thank you very much BN it makes much more sense now.

Hi,

I just download and play with the examples horzPicScroll and horzPicShow into the iPad.

I copied two times the horzPicShow group to test it but only the one that have the layer = 1 work.
Why?

Hi Josep,

I copied two times the horzPicShow group to test it but only the one that have the layer = 1 work.
Why?

because the logic is all in the card script and on openCard triggers a handler "createUIViewScroll". This handler initializes ONE (1) instance of a scrolling area.

If you place 2 horzPicShow groups on the same card the opencard will grab the first "picGroup" group available and that is the one with the lowest layer.

Kind regards

Hi,

horzPicScroll have the logic into the card, yes, but I testing the horzPicShow and in the card haven't any code, all the code is inside the group "picGroup".
In my case I have two groups, "picGroup" and "picGroup2".

Changing the layer value from one to other, produce that run one or other...

Salut,
Josep

Hi Josep,

how do you initialize the scrolling area in the groups ?

I suggest you change all references to picGroup and change them to picGroup2 in the second group. Of Course you would have to rename the group accordingly. (Not tested since I don't know exactly what you are doing)

Kind regards

Bernd
