insertPlainText and carriage return

[RenanBS]

term is a class that descends from QPlainTextEdit.

This is my code:

QByteArray ba = "Test123\r";
term->insertPlainText(ba);
term->insertPlainText("ABC");

QByteArray ba = "Test123\r";
term->insertPlainText(ba);
term->insertPlainText("ABC");

To copy to clipboard, switch view to plain text mode 

I was expecting that the result of this code was like this:

ABCTest123

ABCTest123

To copy to clipboard, switch view to plain text mode 

or

ABCt123

ABCt123

To copy to clipboard, switch view to plain text mode 

ABC should be in the same line that Teste123 was.
But the result is

Test123
ABC

Test123
ABC

To copy to clipboard, switch view to plain text mode 

Just want the carriage return to return the carriage in the same line.
Is it possible or do I have to treat this kind of thing manually?

Thanks is advance
