Add special characters as text to QTextEditor or other widgets

[Q139]

@Pl45m4 If i add another "\" as "l1 \\n l2" then i get "l1 \n l2" to QTextBrowser , but i am unable to write a search function to auto replace every "\" with "\\"

Why not? What did you try?

@Q139

If you have a string, you can simply replace \ with \\

[Q139]

@jsulm

text.indexOf('\'); //wont compile
text.indexOf('\\'); //wont find the text as special chars are threated as single char..

[Q139]

@Pl45m4 how to replace it without seeking for each special char seperately?
After compiled to string it is threated as single special char...
Basically id like to show all info as raw text in text browser. Including \n \r etc but incoming data format is QString...

Of course not.

Regarding text.indexOf('\'); : you want to replace new-lines, right? So, it should be:

text.indexOf('\n');

To replace a simple

someString.replace("\n", "\\n");

[Q139]

@jsulm Not only new lines but all special chars..

I guess 1 way is to loop trough text and use isNonCharacter() then add the extra "\"

@Q139

If you want to replace \ with \\
text.replace ("\\", "\\\" );

@Pl45m4 Nice try

[jsulm]

@Q139 One idea would be to take a look at qDebug() implementation as it does this at least for some special characters (like new lines).

[Q139]

@Q139 im afraid compiler removes 2 chars and replaces with 1 as there are not enough keys on keyboard for special chars.
