I have a string lots\t of\nwhitespace\r\n which I have simplified but I still need to get rid of the other spaces in the string.
QString str = " lots\t of\nwhitespace\r\n "; str = str.simplified(); I can do this erase_all(str, " "); in boost but I want to remain in qt.

Python String strip() function will remove leading and trailing whitespaces. If you want to remove only leading or trailing spaces, use lstrip() or rstrip() function instead.
JavaScript String trim() The trim() method removes whitespace from both sides of a string. The trim() method does not change the original string.
Java has inbuilt methods to remove the whitespaces from the string whether leading, trailing, both, or all. trim() method removes the leading and trailing spaces present in the string. strip method removes the leading and trailing spaces present in the string. Also, it is Uniset/Unicode character aware.
trim() The trim() method removes whitespace from both ends of a string and returns a new string, without modifying the original string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).
str = str.simplified(); str.replace( " ", "" ); The first changes all of your whitespace characters to a single instance of ASCII 32, the second removes that.
