Help text color in TextEdit

[tho97]

Hi,
I want to make error message in TextEdit has red color, so I do like this:

QString tag1 = "<font color = 'red'>";
tag1.append(error);
tag1.append("</font>");
read_textEdit->append(tag1);

but when I select that error message in TextEdit, all other message come up in TextEdit after it will become red. If I don't select it, all other message come up in TextEdit will become black color as default. So how can I fix it? I want only the error message has red color only. I try to do like this but it didn't fix the problem of other message become red also if I highlight the error message in TextEdit.

QString tag1 = "<font color = 'red'>";
tag1.append(error);
tag1.append("</font><font color = 'black'></font>");
read_textEdit->append(tag1);

Qt docs say:

Note: The new paragraph appended will have the same character format and block format as the current paragraph, determined by the position of the cursor.

Try the QTextDocument API:

QTextCursor cur( _ui.textEdit->document() );
cur.movePosition( QTextCursor::End, QTextCursor::MoveAnchor );
cur.insertBlock( QTextBlockFormat() );
cur.insertText( message );

QTextCursor cur( _ui.textEdit->document() );
cur.movePosition( QTextCursor::End, QTextCursor::MoveAnchor );
cur.insertBlock( QTextBlockFormat() );
cur.insertText( message );

use this function:

void WriteLog(QString s, QColor c)
{
	if(s.isEmpty())
		return;
 
	QTextStream theStream(s,IO_ReadOnly);
	QString sColor = "<font color="+c.name()+">";
	while ( !theStream.atEnd() ) 
		read_textEdit->append(QTime::currentTime().toString() + " " + sColor+theStream.readLine());
	//edLog->setParagraphBackgroundColor(edLog->paragraphs()-1,c);
	QFile file( "[LOG FILE NAME].log" ); // Write the text to a file
    if ( file.open( IO_WriteOnly ) ) 
	{
        QTextStream stream( &file );
		for(int i=0;i<m_log->paragraphs();i++)
			stream << read_textEdit->text(i) << "\r\n";
    }
	file.close();
}

void WriteLog(QString s, QColor c)
{
	if(s.isEmpty())
		return;

	QTextStream theStream(s,IO_ReadOnly);
	QString sColor = "<font color="+c.name()+">";
	while ( !theStream.atEnd() ) 
		read_textEdit->append(QTime::currentTime().toString() + " " + sColor+theStream.readLine());
	//edLog->setParagraphBackgroundColor(edLog->paragraphs()-1,c);
	QFile file( "[LOG FILE NAME].log" ); // Write the text to a file
    if ( file.open( IO_WriteOnly ) ) 
	{
        QTextStream stream( &file );
		for(int i=0;i<m_log->paragraphs();i++)
			stream << read_textEdit->text(i) << "\r\n";
    }
	file.close();
}

this function write the string s to the read_textEdit member and a log file(you do not need to use this "file code" if you do not want log file)
each time you want to write to a log file or to the read_textEdit member call this function with any color you want
