I want to get first word of a Qstring.

For example String1 = "Read from file1". I want to extract string2 = "Read". I want to extract substring based on whitespace.

If I encounter a first whitespace in my string1, I need that part of string1 to string2.

Use the split function of QString in this way:

QString firstWord = string1.split(" ").at(0);

If there is no whitespace in the string, the whole string will be returned.
