QTextEdit colored text, again...

[nsvinc]

Hello,

I'm looking for a solution to append single characters to QTextEdit with different colors.
I tried the following:

QTextCursor curs(textCursor());
  QTextCharFormat fmt;
  fmt.setForeground(QBrush(Qt::red));
  curs.setCharFormat(fmt);
  curs.movePosition(QTextCursor::End);
  curs.insertText(QString(chr));

QTextCursor curs(textCursor());
  QTextCharFormat fmt;
  fmt.setForeground(QBrush(Qt::red));
  curs.setCharFormat(fmt);
  curs.movePosition(QTextCursor::End);
  curs.insertText(QString(chr));

To copy to clipboard, switch view to plain text mode 

does not work

setTextColor(kolor1);
  append(QString(chr));

setTextColor(kolor1);
  append(QString(chr));

To copy to clipboard, switch view to plain text mode 

does not work either

The only thing that actually works, is the <font> tag

append(QString("<font color=red>%1</font>").arg(chr));

append(QString("<font color=red>%1</font>").arg(chr));

To copy to clipboard, switch view to plain text mode 

The problem is, I'm getting the input char by char, and cannot combine it into QString easily; every new character could have a different color. I would like to find a way other than tagging every single character (which would yield tons of garbage text not seen by the user, and would be probably not speed efficient).

It would be nice, if QTextEdit remembers the last color setting, and appends new characters with that color...

As far as I know it's not possible. You can either set background/text color for entire QTextEdit or use html as You have done. It is possible to create function that will wrap Your char into html and set random color and function that will take back only char from html. The second is easy. You can take entire text from QTextEdit, put it in QTextDocument object and use function toPlainText(), then you have Your text as QString without any html.
