Hide/Unhide a calendar from an AppleScript program

Question

Is there a way for an AppleScript program to hide/show a particular calendar in iCal V4.0.3?
There's a checkbox right next to the name of the calendar that does exactly what I want -- with the mouse. I'd like to control that checkbox from an AppleScript program.

Answer 1

My sincere apologies to the author, because I cannot remember where I got it, but this works:
tell application "System Events"
tell application process "iCal"
tell front window
--log "count of scroll areas=" & (count of scroll areas)
repeat with SA in scroll areas
tell SA
--log "count of outlines=" & (count of outlines)
repeat with OutL in outlines
tell OutL
--log "count of rows=" & (count of rows)
repeat with aRow in rows
tell aRow
--log "count of text fields=" & (count of text fields)
--log "value of text field 1=" & value of text field 1
--repeat with aTF in text fields
-- tell aTF
-- -- log value --> Can't get
-- end tell
--end repeat
if value of first text field is "MCCVin" then
--log "count checkboxes=" & (count checkboxes)
click checkbox 1
end if
end tell
end repeat
end tell
end repeat
end tell
end repeat
end tell
end tell
end tell
