Antwort auf: Problem mit mobile Scroller

[wfr]

Habe den Code umgebaut, aber hat nichts geändert.

Stack2, card b1:

on preOpenCard
   local sScrollerID
   local tScrollerRect, tContentRect
   // Only create a scroller on a mobile device
   if environment() is not "mobile" then exit preOpenCard
   put the rect of group "scrollArea" into tScrollerRect
   put 0,0,(the formattedWidth of group "scrollArea"),(the formattedHeight of group "scrollArea") into tContentRect
   // Create the scroller control
   mobileControlCreate "scroller", "my_scroller1"
   put the result into ssScrollerID
   // Set the properties of the scroller
   mobileControlSet "my_scroller1", "rect", tScrollerRect
   mobileControlSet "my_scroller1", "contentRect", tContentRect
   mobileControlSet "my_scroller1", "visible", true
   mobileControlSet "my_scroller1", "scrollingEnabled", true
   mobileControlSet "my_scroller1", "vIndicator", true
   mobileControlSet "my_scroller1", "vscroll", 0   
end preOpenCard

on closeCard
   // Delete the scroller
   global sScrollerID
if environment() is not "mobile" then exit closeCard
mobileControlDelete sScrollerID
end closeCard

Stack2:

on scrollerDidScroll hOffset, vOffset
   // When the user scrolls move the displayed content
   set the vScroll of group "scrollArea" to vOffset
end scrollerDidScroll

Stack3, card c1:

on preOpenCard
   local sScrollerID
   local tScrollerRect, tContentRect, vOffset
   // Only create a scroller on a mobile device
   if environment() is not "mobile" then exit preOpenCard
   put the rect of group "scrollArea" into tScrollerRect
   put 0,0,(the formattedWidth of group "scrollArea"),(the formattedHeight of group "scrollArea") into tContentRect
   // Create the scroller control
   mobileControlCreate "scroller", "myscroller_2"
   put the result into ssScrollerID
   // Set the properties of the scroller
   mobileControlSet "myscroller_2", "rect", tScrollerRect
   mobileControlSet "myscroller_2", "contentRect", tContentRect
   mobileControlSet "myscroller_2", "visible", true
   mobileControlSet "myscroller_2", "scrollingEnabled", true
   mobileControlSet "myscroller_2", "vIndicator", true
   mobileControlSet "myscroller_2", "vscroll", 0   
end preOpenCard

on closeCard
   // Delete the scroller
   global sScrollerID
   if environment() is not "mobile" then exit closeCard
   mobileControlDelete sScrollerID
end closeCard

Stack3:

on scrollerDidScroll hOffset, vOffset
   // When the user scrolls move the displayed content
   set the vScroll of group "scrollArea" to vOffset
end scrollerDidScroll

Ich beschreibe nochmals das Szenario:
– ich starte das Programm
– ich springe von stack1 auf stack2 —> scroller funktioniert!
– ich springe zurück zu stack1
– ich springe von stack1 auf stack3 —> scroller funktioniert!
– ich springe zurück zu stack1
– ich springe von stack1 auf stack2 —-> scroller funktioniert nicht mehr!

echt mysteriös….
