Isuue with /n in Qt Creator

[mulfycrowh]

Hi everybody !

I am using Qt Creator with VS2012 compiler.
I declared a QByteArray variable : T
I initialized it. Everything OK.
I added the line :

T += "\n";

What follows gives me an exception and I think that the issue comes from this added line. As I take a look at T in the debugger, I don't see any \n but a point .

Could you explain please ?
Many thanks.

"\n" is not a byte but char array (more precisely: a pointer to the first element of the char array)
So why do you add it to the QByteArray instance?
Perhaps you wanted to do

T += '\n';

I mean LF that has ascii code 10.
Why can't I see in the debugger window. It's displayed as a "."

How it is displayed depends on the debugger or/and IDE.
How did you expect it to be displayed?

For example, I expected to see:

T "On the air\n"

And I see :

T "On the air."

For example, I expected to see:

T "On the air\n"

Hmm, I never saw any debugger showing LF as '\n'" in a debugger window.
Note that LF (as well as CR, TAB and many others) are non-printable symbols! And displaying them as '\n' (or '\r', '\t') would confuse user because he/she would think there are two characters: backslash and 'n'!

lf, cr, tab etc are non-printable chars in the ASCII code set. These type of chars are shown as a '.' when trying to display text. If you want to see these non-printable chars then you will need to display in hex when lf will shown as 0a etc.

Ok but I have another computer running another software in Qt Creator. It displays the string as \n. So I don't understand. I looked for some settings in Qt Creator but I didn't find anything. Weird ...
