How to change the text color in QPlainTextEditor?

Code:

---

void writeToEditor( QString partOfText, double readBytes )
    {
        QString newFormat;
        for( int i = 0; i < readBytes; i = i + 10 )
        {
            QStringRef subString( &partOfText, i, 10 );
            newFormat.append( subString );
            newFormat.append( "   " );
        }
 
        objQPlainTextEdit.appendPlainText( newFormat );
 
    }

---

Here objQPlainTextEdit is an object of QPlainTextEdit.

Considering: https://doc.qt.io/qt-5/qplaintextedit.html

Each character within a paragraph has its own attributes, for example, font and color.

I can see there is QPalette. How to use it to color the alphabets displayed in QPlainTextEdit, differently?

For example: 'A' should be of red color, and 'B' should be of green colour.

See https://doc.qt.io/qt-5/qplaintextedi...rentCharFormat

I solved it.

Here is the working code:

Code:

---

QString combineHtml = "<p>";
 
    for( int j = 0; j < readBytes; j++)
    {
        if( partOfText[j] == 'A' )
        {
            combineHtml.append( QString( "<span style = 'color: red'>")
                + QString( partOfText[j]) +  QString( "</span>"));
        }
        else
        {
            combineHtml.append( QString( "<span style = 'color: blue'>")
                + QString( partOfText[j]) +  QString( "</span>"));
        }
    }
 
  combineHtml.append( "</p>");
 
  std::cout << combineHtml.toStdString();
 
  objQPlainTextEdit.appendHtml( combineHtml );

---

Here partOfText is QString, and objQPlainTextEdit is an object of QPlainTextEdit.

Output generated by the above code is as follows:

Code:

---

<p><span style = 'color: blue'>C</span><span style = 'color: red'>A</span><span style = 'color: red'>A</span><span style = 'color: blue'>T</span><span style = 'color: blue'>C</span><span style = 'color: blue'>T</span><span style = 'color: blue'>C</span><span style = 'color: blue'>C</span><span style = 'color: red'>A</span><span style = 'color: blue'>T</span></p>]
