Scrolling a group

Hi,
I'm lost about how deal with this.
I have a image, 2048x1536 pixels, not retina scale, only a big background. With this image I group some other images, so I have a group that I want scroll. With "grab me" command all is ok. I can scroll and "click" over the images inside the group, but when I apply a "scroll" object nothing work. Also I need a toolbar over the scroll region, so the user must actuate clicking the images inside the group and the toolbar.
I post a image for a best explantion.
The blue area is the image and the stars are the controls that from the group.
It's posible do that I need? Any experience?
Salut,
Josep M

see the attached app call mapscroll.livecode. similar to what you are doing, except it's a map and has groups with buttons on it that when clicked gives the name of the country.

Hi Scotty,
Big thanks!
just what I need.
In my code I assign the rect and the contentrect directly from the image properties, this is basically the difference, and the "grab me"
One question more. How drag a button inside the scroll group? With "grab me" only I move a little but don't work.
I need a "double tap" to create a object inside the map group and move it to a desired position. Any idea how do that?
Salut,
Josep M

That's a dangerous question. Your asking to move a object in a moving object. I've never tried moving an object in a scroll group!

And scroll to a region? In your example, the user click into the toolbar to show europe, usa, asia... and the scrolling move to the x,y position into the scroller...

Hi,
Autoanswer...
To scroll to any X,Y use and put at mainstack or card level where you create the scroller.
Code: Select all
on moveTo vS,hS
iphoneControlSet sScrollerId, "vscroll", vS
iphoneControlSet sScrollerId, "hscroll", hS
end moveTo

Hi,
I try to positionate the scroller into a X,Y in the preOpenCard but nothing happen, nor OpenCard...
Code: Select all
on opencard
if the environment is not "mobile" then
exit opencard
end if
iphoneControlSet sScrollerId, "hscroll", 2126
iphoneControlSet sScrollerId, "vscroll", 355
end opencard
But If I call this from a button, work.
What I'm doing wrong?
Salut,
Josep M
