[MacPerl-Toolbox] window/Mac::TextEdit question

[James Lund <jsl21053@welch.jhu.edu>]

I'm porting a program to the Mac, trying to replace the command line args
with a settings box that pops up when the program is run.  I'm having trouble
dealing with the text input boxes, they pop up fine, but I can't set them or
get the user input value out.  

The problem seems to be that I don't understand where the reference is coming
out of the call to make the text box using Mac::TextEdit.
Can someone point out where I lost my handle?


Thanks,

Jim Lund
