hi all,<br>
<br>
I have build a GUI using qt-embedded, which is <b>writing</b> and then
<b>reading</b> from serial port. So i wana display the read data on to
screen. Here i am using QTextEdit in loging mode. I wana append the
data in QTextEdit area.(i.e.All previous data should be there). But the
problem is that it is not appending, it replaces previous line with the
current line. I have tried insert() also. Please anybody suggest me,if
any thing wrong with following code or else? <br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; QTextEdit *log=new QTextEdit(bgrp2,0);<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; log-&gt;setTextFormat( Qt::LogText );<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; log-&gt;setGeometry(5,113,198,70);<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; log-&gt;append(qstring);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // qstring , reading from
serial port<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp; log-&gt;show();&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>
<br>
<br>
Thank you.<br>
<br>
Warm Regards,<br>

I don't understand. Above a QTextEdit is created and qstring is appended 
to it. I see no "previous line" or "current line".
