From ee4d1493e2a871b26201580c5a990a1df7a5e3f7 Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Fri, 7 Jul 2017 17:09:55 -0400 Subject: [PATCH] Drop upgrade-cancel callback registration for a generic "resumeable" Instead of passing a StartShutdown reference all the way up from txdb, give ShowProgress a "resumeable" boolean, which is used to inform the user if the action will be resumed, but cancel is always allowed by just calling StartShutdown(). --- src/qt/splashscreen.cpp | 32 +++++++++++--------------------- src/qt/splashscreen.h | 4 ---- src/txdb.cpp | 6 +++--- src/ui_interface.h | 10 +++++----- src/validation.cpp | 12 ++++++------ 5 files changed, 25 insertions(+), 39 deletions(-) diff --git a/src/qt/splashscreen.cpp b/src/qt/splashscreen.cpp index 1b7cc6923..a1fbba963 100644 --- a/src/qt/splashscreen.cpp +++ b/src/qt/splashscreen.cpp @@ -142,8 +142,8 @@ SplashScreen::~SplashScreen() bool SplashScreen::eventFilter(QObject * obj, QEvent * ev) { if (ev->type() == QEvent::KeyPress) { QKeyEvent *keyEvent = static_cast(ev); - if(keyEvent->text()[0] == 'q' && breakAction != nullptr) { - breakAction(); + if(keyEvent->text()[0] == 'q') { + StartShutdown(); } } return QObject::eventFilter(obj, ev); @@ -170,27 +170,18 @@ static void InitMessage(SplashScreen *splash, const std::string &message) Q_ARG(QColor, QColor(55,55,55))); } -static void ShowProgress(SplashScreen *splash, const std::string &title, int nProgress) +static void ShowProgress(SplashScreen *splash, const std::string &title, int nProgress, bool resume_possible) { - InitMessage(splash, title + strprintf("%d", nProgress) + "%"); -} - -void SplashScreen::setBreakAction(const std::function &action) -{ - breakAction = action; -} - -static void SetProgressBreakAction(SplashScreen *splash, const std::function &action) -{ - QMetaObject::invokeMethod(splash, "setBreakAction", - Qt::QueuedConnection, - Q_ARG(std::function, action)); + InitMessage(splash, title + std::string("\n") + + (resume_possible ?
