W-A-A-I-I-T, don't cash that check!!!
Humm. Alright. In the actual application there
is probably a very small chance something like this
could happen, but it is not impossible.
The code is simple enough, I'll make it available
for anyone who wants to have a go at solving this
problem. You can find it here:
ftp://ftp.dfanning.com/pub/dfanning/outgoing/misc/recorder__ define.pro
You will get it running like this:
IDL> o = obj_new('recorder', text=['pig','dog','cow','pig','coyote'])
IDL> o->gui
You can add text to it like this:
IDL> o->AddText, 'rooster'
The code you want to fool around with is in the object
method named Recorder::DeleteIt.
So many people are involved now I should offer a prize.
OK, First Prize is Liam's book, Last Prize is my book. :-(
Cheers,
David
