      Hello,

      In QSyntaxHighlighter::highlightBlock(), QSyntaxHighlighter::setUnderlineStyle() and QSyntaxHighlighter::setUnderlineColor() don't work as intended.

      Similar to https://bugreports.qt.io/browse/QTBUG-87260, which actually never solved the underlines in QtQuickControls2's TextArea.

       

      See the screenshot:

      • QTextCharFormat::DashUnderline doesn't show.
      • QTextCharFormat::WaveUnderline doesn't show.
      • Red QTextCharFormat::SingleUnderline shows only in black.

       

      You can test it with the attached test project. highlighter.cpp highlights the problem, pun intended.

      Edit : Still not solved in 6.9.1
