Print an array into a scrollField

[davus]

So the problem I face is that I have an array that I want to use as text in a scrollField. What I need it to do is write each element of the array onto a different line of the scrollField.

similar to:

for ($eachFile in $Files){
    print ($eachFile + "\n");
    }

...but I need that to work here:

string $scrollField = scrollField -e -text ("$eachFile printed onto a new line") scrollField;

Any thoughts???
Thanx for any help!

ok- I've got it working. I was trying to be too fancy about it, but it's actually very simple.

my thanks to the authors at http://www.scriptswell.net

proc getTxt (){

     string $getTxtPath[] = fileDialog2 -fileMode 4 -dialogStyle 1; //Dialog to find file

     $txtFile = fopen $getTxtPath[0] "r" ;

     string $content = fread $txtFile $content ;

    scrollField -e -text $content scriptTxt;

}

OK, so my problem exists again. I've run into the Byte size limitation of "fread"  ...I think my solution now is to read my text file line by line and write that to a variable. That's no trouble, but how do I then edit the text of my scrollField having each member of the array being its own line?  Is there a way to append to the existing text in the scroll Field rather than completely replacing it?

by adding the data to a single variable over and over (or using the stringArrayToString command)

Method 1:
string $list[]={"one","two","three"} ;
string $data ;
for($item in $list)
    $data+=$item+"\n" ;
print $data ;

Method 2:string $list[]={"one","two","three"} ;string $data=stringArrayToString($list,"\n") ;print $data ;

Thanks for the reply, but those don't really for my situation. Below is the proc that I ended up using with success. Basically it reads one line of the file at a time and then prints it into the scrollfield based on an insertion point and line number. This kept the text below the 1024 byte limitation.

proc getTxt(){

    string $getTxtPath[] = fileDialog2 -fileMode 4 -dialogStyle 1; //Dialog to find file

    textField -e -text $getTxtPath txtField; // Edits the text field with file path

    $fileId = fopen $getTxtPath[0] "r" ;

    string $nextLine = fgetline $fileId;

    for($i=0; $i < size($nextLine); $i++){

        while ( size( $nextLine ) > 0 ) {

            print ( $nextLine );

            scrollField -e -ip $i -it $nextLine scriptTxt;    

            $nextLine = fgetline $fileId;

        }

    }

    fclose $fileId;

}
