From 6da12dff287ac08c1d8aa847794abb8e582d606c Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Tue, 1 Dec 2015 11:45:33 +0100 Subject: qt: use QMetaObject::invokeMethod for cross-thread signaling in clientmodel It's surprising to me that Q_EMIT even worked for this. But it doesn't build in Qt4, so switch back to `QMetaObject::invokeMethod`. Fixes #7138. --- src/qt/clientmodel.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src/qt') diff --git a/src/qt/clientmodel.cpp b/src/qt/clientmodel.cpp index d36d129c1a..8149dfdf5a 100644 --- a/src/qt/clientmodel.cpp +++ b/src/qt/clientmodel.cpp @@ -253,7 +253,10 @@ static void BlockTipChanged(ClientModel *clientmodel, bool initialSync, const CB // if we are in-sync, update the UI regardless of last update time if (!initialSync || now - nLastBlockTipUpdateNotification > MODEL_UPDATE_DELAY) { //pass a async signal to the UI thread - Q_EMIT clientmodel->numBlocksChanged(pIndex->nHeight, QDateTime::fromTime_t(pIndex->GetBlockTime()), clientmodel->getVerificationProgress(pIndex)); + QMetaObject::invokeMethod(clientmodel, "numBlocksChanged", Qt::QueuedConnection, + Q_ARG(int, pIndex->nHeight), + Q_ARG(QDateTime, QDateTime::fromTime_t(pIndex->GetBlockTime())), + Q_ARG(double, clientmodel->getVerificationProgress(pIndex))); nLastBlockTipUpdateNotification = now; } } -- cgit v1.2.3
