We should # only access the attributes pointer when some text actually exist. # # Task-number: QTBUG-24718 # Change-Id: I9ce9f7b57bccf24099a02832ce30fb6cebfaad33 # diff --git a/src/gui/text/qtextlayout.cpp b/src/gui/text/qtextlayout.cpp index ee658d9..16f7150 100644 --- a/src/gui/text/qtextlayout.cpp +++ b/src/gui/text/qtextlayout.cpp @@ -2508,6 +2508,10 @@ qreal QTextLine::cursorToX(int *cursorPos, Edge edge) const int pos = *cursorPos; int itm; const HB_CharAttributes *attributes = eng->attributes(); + if (!attributes) { + *cursorPos = 0; + return x.toReal(); + } while (pos < line.from + line.length && !attributes[pos].charStop) pos++; if (pos == line.from + (int)line.length) {
