[JW Lua] FCPageTexts - Retrieve Item at a specific index

[Jari Williamsson]

Bruce,

You're correct about how the ItemCmper/ItemInci works in connection with 
FCPageText. However, you should rarely need to know that for most kind 
of script programming. :-)

In your first message, you said you wanted to iterate through all the 
page text. This is done with something similar to:
---
local pagetexts = finale.FCPageTexts()
pagetexts:LoadAll()
for ptext in each(pagetexts) do
    local rawstr = ptext:CreateTextString()
    print("First page:", ptext.FirstPage, "Last page:", ptext.LastPage, 
"Raw string:", rawstr.LuaString)
end
---

It's not possible to locate text block data in any pre-determined order. 
Data is added/removed as required in the order the user decides to do it.


Best regards,

Jari Williamsson
