How to change the colour of a QTextBlock in a QTextEdit

Olivier Ronat

Hello
I want to change the colour of the text (black to red) in a block of a QTextEdit and I wrote the following function :

setColourBlock(QTextBlock bloc)
{
QTextCursor cursor(bloc);
cursor.movePosition(QTextCursor::StartOfBlock,QTextCursor::MoveAnchor);
cursor.movePosition(QTextCursor::EndOfBlock,QTextCursor::KeepAnchor);
QTextCharFormat tcf = cursor.charFormat();
QBrush brush = tcf.foreground();
brush.setColor(Qt::blue);
tcf.setForeground(brush);
cursor.setCharFormat(tcf);
}
The text is well selected, the brush is now blue but the text in the block remains black. What did I forget to do?
Thank you for your kind answer

Hi,

What if you replace:
@Olivier-Ronat said in How to change the colour of a QTextBlock in a QTextEdit:

QBrush brush = tcf.foreground();
brush.setColor(Qt::blue);
tcf.setForeground(brush);

with just:

tcf.setForeground(Qt::blue);

?

Nothing is changed

Found the issue.
It is not a QT one but the block parameter in the calling function was coming from a const QTextEdit so it can change anything in it. Yhank you for the time you spent to answer me.
