[Qt-interest] QTextEdit line color

[RZ]

Answering myself and raising another question:

QTextCursor tc(m_TextBlock);
QTextBlockFormat blockFormat = m_TextBlock.blockFormat();
blockFormat.setForeground(Qt::green);  <-- this does not work
blockFormat.setBackground(Qt::red);  <-- this works
tc.setBlockFormat(blockFormat);
