Details of ThreadSafeMessageBox using in Bitcoin Core

ThreadSafeMessageBox.md

The ThreadSafeMessageBox() messages are rendered in two ways:

• by noui_ThreadSafeMessageBox() using LogPrintf() and fprintf(stderr, ...) with adding translated type prefix ("Error" / "Warning" / "Information")
• by BitcoinGUI::message() using QMessageBox with adding translated type suffix ("Error" / "Warning" / "Information") to the window title. Note: On macOS, the window title is ignored (as required by the macOS Guidelines)

The ThreadSafeMessageBox() is called by some functions:

• AbortNode() and InitRPCAuthentication() pass translated messages with "Error: " prefix
• FatalError() passes non-translated messages with "Error: " prefix
• InitError(); some passed messages are translated, some are not
• InitWarning() passes translated messages
• InitHTTPAllowList() passes non-translated messages
• CCoinsViewErrorCatcher::GetCoin() pass translated message started with "Error"
• CConnman::BindListenPort() via CConnman::Bind() passes:
  • non-translated messages with "Error: " prefix
  • translated messages without any prefix
  • translated messages with "Error: " prefix
• CConnman::Start() passes translated messages
