[Qt-interest] QTextEdit: insertPlainText at the end of the "text" keeping current output font style

[Torsten Krah]

Hi.
I am going to output telnet data (text) in a QTextEdit view.
I am not using append because the text is using ansi style colors and i am 
going to parse them and change the font on my QTextEdit view while processing 
the telnet input and writing the text to the view whenever needed (new color 
or something else).

This works fine so far, however if the user scrolls and the current cursor is 
not at the end and input is received from the telnet stream its not written at 
the correct destination (End).

I tried to use this:

	QTextCursor c = ui.output->textCursor();
	c.movePosition(QTextCursor::End);
	ui.output->setTextCursor(c);
	ui.output->ensureCursorVisible();
	ui.output->insertPlainText(text);

which solves my problem that the text is not inserted at the end of the 
output.
But my styles are lost - all settings done to the view like:

setTextBackgroundColor or setTextColor 

while parsing my raw input is lost.
Without this cursor stuff above color & co are there.

So why are these settings lost and how can i have both, keeping my settings on 
the output view and scroll the cursor to the end and insert text there?

thx for help.
