From cb1035a00882405fac47eb92e7086c7231062e3d Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Sat, 14 Apr 2012 09:41:05 +0200 Subject: [PATCH] Show a message box when runaway exception happens This is more clear to users than when the program simply disappears (usually during initialization). It still logs the message to the console and debug log as well. --- src/qt/bitcoin.cpp | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/src/qt/bitcoin.cpp b/src/qt/bitcoin.cpp index 1133f122e73..74ace600e0f 100644 --- a/src/qt/bitcoin.cpp +++ b/src/qt/bitcoin.cpp @@ -120,6 +120,15 @@ std::string _(const char* psz) return QCoreApplication::translate("bitcoin-core", psz).toStdString(); } +/* Handle runaway exceptions.
