[Qt-interest] Newline character in QLineEdit

[Robert Escott]

Hi Surya

 

The \n escape sequence is only understood by the compiler and is converted to the newline character when you compile your source. 

 

If you want your program to understand that the character sequence entered by users as the newline character then you need to program this in yourself. The easiest way is to user the replace function of QString.

 

Eg. QString userText = lineEdit->text().replace(“\\n”, ‘\n’).replace(“\\t”, ‘\t’);

 

I can’t think of why you’d actually want to do this. The QTextEdit or QPlainTextEdit widgets make more sense if you want multi-lined input.

Hello all,
I'm trying to get user input in QLineEdit, User may type in newline character as \n, but QLineEdit is returning the \n as a QString of 2 characters instead of one. 

How to force QLineEdit to correctly return characters like \n, \t etc.

Thanks,
Surya
