From daea63e8c5eff7a03b32729862fff6c18a70aebb Mon Sep 17 00:00:00 2001 From: Douglas-Richardson Date: Sat, 22 Apr 2017 20:54:09 -0400 Subject: Fixed the crashing bugs It technically doesn't crash, but for some reason the GUI is frozen immediately on startup and is completely unresponsive. It may have something to do with calling some function in them multiple times over and over again but I don't know. I added some debugging text with comments next to them as "eat this note". Those lines can be removed with no concequences. --- Hermes/Hermes_Gui1.3.rkt | 9 +++++++-- Hermes/client.rkt | 30 +++++++++++++++++------------- Hermes/server.rkt | 14 ++++++++------ 3 files changed, 32 insertions(+), 21 deletions(-) diff --git a/Hermes/Hermes_Gui1.3.rkt b/Hermes/Hermes_Gui1.3.rkt index 8700432..19df04b 100644 --- a/Hermes/Hermes_Gui1.3.rkt +++ b/Hermes/Hermes_Gui1.3.rkt @@ -13,6 +13,7 @@ (define (make-gui) (begin + (displayln "Makin...");;eat this note ;;Create the frame (define main-frame (new frame% [label "Hermes"] @@ -88,7 +89,9 @@ (helper string start)) (define (user-message onetrueinput) - (if (string? onetrueinput) + (display "Godit!");;eat this note + (displayln onetrueinput);;eat this note + (if (not (string=? onetrueinput "")) (let();;This is kind of stupid but whatever it works.
