If I do Alt+Left/Right, only the text editor tab changes. The document view changes only when I click ViewPDF or ForwardPDF. It also does not crash if I do it faster than usual on my slowbook. ;) 2087576 2 nate 2021-12-22 19:13:27 +0000 Yep. And when the text editor tab changes, the Okular-provided preview changes too. I should note that when I reproduce this, at least one of the tabs is a simple .txt file that doesn't get rendered by the Okularpart preview. It doesn't happen when all of the tabs contain .tex files. 2087577 3 nate 2021-12-22 19:14:14 +0000 Maybe there's an "automatically reload preview" setting that I turned on ages ago. Either way, the Okularpart preview does update automatically for me when I switch tabs. 2087832 4 aacid 2021-12-23 22:02:54 +0000 it's re-entering the closeDocument method because you press the shortcuts faster than it takes for cancelling the running threads. If you can reproduce this easily you need to add a bool in document that is "i am closing" and then check it first thing in closedocument, if it's already closing just return, if not set it to true and then set it to false at the end of the function. Can you check if that helps? 2100560 5 nate 2022-02-03 02:53:38 +0000 Nope, that doesn't fix it, assuming I did it right: diff --git core/document.cpp core/document.cpp index b6be827f1..9a80db24f 100644 --- core/document.cpp +++ core/document.cpp @@ -2486,10 +2486,12 @@ KXMLGUIClient *Document::guiClient() void Document::closeDocument() { - // check if there's anything to close... - if (!d->m_generator) + // check if there's anything to close or if we are already closing... + if (!d->m_generator || d->m_isClosing) return; + d->m_isClosing = true; + emit aboutToClose(); delete d->m_pageController; @@ -2639,6 +2641,7 @@ void Document::closeDocument() // see: https://sourceware.org/bugzilla/show_bug.cgi?id=14827 malloc_trim(0); #endif + d->m_isClosing = false; } void Document::addObserver(DocumentObserver *pObserver) diff --git core/document_p.h core/document_p.h index bd932db37..c8c93c47a 100644 --- core/document_p.h +++ core/document_p.h @@ -129,6 +129,7 @@ public: , m_annotationBeingModified(false) , m_docdataMigrationNeeded(false) , m_synctex_scanner(nullptr) + , m_isClosing(false) { calculateMaxTextPages(); } @@ -345,6 +346,8 @@ public: static QVector<KPluginMetaData> availableGenerators(); static QVector<KPluginMetaData> configurableGenerators(); static KPluginMetaData generatorForMimeType(const QMimeType &type, QWidget *widget, const QVector<KPluginMetaData> &triedOffers = QVector<KPluginMetaData>()); + + bool m_isClosing; }; class DocumentInfoPrivate 2100650 6 aacid 2022-02-03 13:10:12 +0000 That sounds like what i meant yes.
