[QTextCursor & QTextBlock] Inserting TextBlock without <br>

[zavafoj]

Hello.

I am trying to create IO rich-text based console widget using QTextBlock & QTextCursor.
Is it possible to disable breakline character after inserting new QTextBlock?

Hmm.... what sense would it make to do that?

I want to append QTextEdit with rich text from userInput, USB or TTY Console
with limited count of displayed characters (only newest data should be visible).
I wondered to insert new block each time device has answered, but it is
inserting new paragraph (with additional break line in document).

My code:

QScrollBar *p_scroll_bar = this->verticalScrollBar();
    bool bool_at_bottom = (p_scroll_bar->value() == p_scroll_bar->maximum());
    QTextCursor appendTextCursor = this->textCursor();
 
    if(addBr)
        appendText.append("<br>");
 
    appendText = QString("<font color = %1>%2</font>")
            .arg(this->_isDevice? this->_deviceColor.name() : this->_commandLineColor.name())
            .arg(appendText);
 
    this->_containingText.append( appendText );
 
    qDebug() << appendText;
 
    appendTextCursor.movePosition(QTextCursor::End);
    appendTextCursor.insertBlock();
    appendTextCursor.beginEditBlock();
    appendTextCursor.insertHtml(appendText);
    appendTextCursor.endEditBlock();
 
    if (bool_at_bottom)
    {
        p_scroll_bar->setValue(p_scroll_bar->maximum());
    }

QScrollBar *p_scroll_bar = this->verticalScrollBar();
    bool bool_at_bottom = (p_scroll_bar->value() == p_scroll_bar->maximum());
    QTextCursor appendTextCursor = this->textCursor();

    if(addBr)
        appendText.append("<br>");

    appendText = QString("<font color = %1>%2</font>")
            .arg(this->_isDevice? this->_deviceColor.name() : this->_commandLineColor.name())
            .arg(appendText);

    this->_containingText.append( appendText );

    qDebug() << appendText;

    appendTextCursor.movePosition(QTextCursor::End);
    appendTextCursor.insertBlock();
    appendTextCursor.beginEditBlock();
    appendTextCursor.insertHtml(appendText);
    appendTextCursor.endEditBlock();

    if (bool_at_bottom)
    {
        p_scroll_bar->setValue(p_scroll_bar->maximum());
    }

To copy to clipboard, switch view to plain text mode

So don't insert a new block but rather append to the existing one.

Sure, I tried to append previous textBlock, but my widget worked extremely slow.
By adding insertBlock(); widget worked properly, but it appends brs.
