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

[Bruce Olson]

Jari,

Thanks, the iterating through part I have. What I want to do is load a
specific FCPageText after I have once iterated through it. My first pass
using code like you posted below modifies a table with the FirstPage and 5
other values. 

Then I loop through this table to see which rows are nil and which were
found. If it was found in the first pass then determine using
IsEnigmaFileInfoTitle() which one it is, and modify some values using the
data from a second table. If it was not found in the first pass, then add it
using the data from the second table. The second table is in the same order
as the first table.

I hope that makes sense.

Bruce

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
