Hi

I have a small script.

##

set ::nix {{nix0 5 p-4 o0} {nix11 6 p-3 o2}}

::tablelist::tablelist .tbl -listvariable ::nix\
-columns "0 col1 left 0 col2 right 0 col3 center 0 col4 center"
.tbl columnconfigure 0 -name col0
.tbl columnconfigure 1 -name col1
.tbl columnconfigure 2 -name col2
.tbl columnconfigure 3 -name col3
pack .tbl



puts "itemtodict : [.tbl itemtodict 0]"

##

the puts command show me: % itemtodict : col0 0 col1 {} col2 {} col3 {}

I expected that I get "col0 nix0 col1 5 col2 p-4 col3 o0".

I'll get all values from a row with columnname like a dict.

What do I wrong or I don't understand?



regards

Manfred

If I understand the 'itemtodict' command correctly, it will not return
the values of the *table*, but from the *item* you passed to it.

https://www.nemethi.de/tablelist/tablelistWidget.html#itemtodict
[...]
The dictionary's keys will be column numbers or names, and the values
will be the corresponding elements of the given item.
[...]

Since the only value in the item is '0', you get empty strings for the
rest.

Hi

Thank's for your answer.

I know, that I don't get the values from the table,
but I thought the first row is the first item.
The first row has the values "nix0 5 p-4 o0".

I set the variable ::nix with {{nix0 5 p-4 o0} {nix11 6 p-3 o2}}
which is the listvariable of the table an which is shown in the first
row in the table.

I'll ask another question.
Who can I get all values of a row from the table with the columnnames?

with: ".tbl rowcget 0 -text" I only get the value, but I'll get the
columnname and the values like a dict.


regards

Manfred

That's true, but 'item' in this context does not mean "item in the
tablelist", it literally means the 'item' argument to the 'itemtodict'
command, which is not some kind of index into the tablelist, but the
literal values:

puts "itemtodict : [.tbl itemtodict {nix0 5 p-4 o0}]"
itemtodict : col0 nix0 col1 5 col2 p-4 col3 o0

That would probably be

.tbl itemtodict [.tbl rowcget 0 -text]

The itemtodict subcommand expects as its first argument an item (i.e., a
list of elements), not an item index. To get and print the desired
dict, use

puts "itemtodict : [.tbl itemtodict [.tbl rowcget 0 -text]]"

or

puts "itemtodict : [.tbl itemtodict [.tbl get 0]]"

Oops, I have basically written the same as Ralf. It was not before

Always good to get confirmation from *the* boss himself ;-)
