Picture-Scroller with a group?

Hi there,
I want to build a horizontal scroller for some pictures inside an App.
I need to fill the scroller with pictures at runtime.
Has anyone experiences with something like this and can give me an examples?
Maybe it is possible to build a group, which is bigger than the screen and hide the scoller-bars? But if this could work, how to add/remove pictures at runtime in this group?
Thank you!!

Yes, and you can scroll your group with Horizontal or vertical move
You can see one example called "StResizeAndMoveGroupH" from revOnline
But if this could work, how to add/remove pictures at runtime in this group?
You can copy one control in your group
Code: Select all
copy control "ImageMaster" to group pGroup
and set the properties of all controls of group in a loop

Welcome,
Once you have created all controls of your group you can set the properties of all controls of group.
As properties I mean "location,rect, filename etc...
This script place all images of a group verticaly
Code: Select all
on doImgGroupVertical
put the num of images of group "grMyGroup" into nbImg
put the bottomleft of image 1 of group "grMyGroup" into tDepBL
repeat with i = 2 to nbImg
set the topleft of image i of group "grMyGroup" to tDepBL
put the bottomleft of image i of group "grMyGroup" into tDepBL
add 2 to item 2 of tDepBL --marginV 2 px
wait 1 milliseconds
end repeat
end doImgGroupVertical
Best regards
