Question

This snippet can only highlight current line, but it cannot highlight line with soft wraps.

 def highlightCurrentLine(self):
 extraSelections = []
 if not self.isReadOnly() and self.toPlainText(): # and self.toPlainText()
 selection = QTextEdit.ExtraSelection()
 lineColor = QColor(Qt.yellow).lighter(160)
 selection.format.setBackground(lineColor)
 selection.format.setProperty(QTextFormat.FullWidthSelection, True)
 selection.cursor = self.textCursor()
 selection.cursor.clearSelection()
 extraSelections.append(selection)
 self.setExtraSelections(extraSelections)

• musicamante: Why are you using QTextEdit.ExtraSelection() instead of extraSelections()? Also, please provide a minimal reproducible example.
• Jason: @musicamante I just reuse other people's code. QTextEdit.ExtraSelection() will exit with -1073740791 (0xC0000409)
• musicamante: Then those people are wrong, or you didn't use their code properly. We still need a proper MRE, though.
