How to become int from code ASCII nummer?

[rickbsgu]

QString:perator[] returns QChar which has an isDigit() method.

Right. But that just returns a boolean indicating whether it's a digit or not.

Here's one way:

QString aString("aString");
 
char *str = aString.ascii();      // returns a C-String
int asciiVal = str[0];     // 0x61 - or just use str[0]

QString aString("aString");

char *str = aString.ascii();      // returns a C-String
int asciiVal = str[0];     // 0x61 - or just use str[0]

To copy to clipboard, switch view to plain text mode 

or:

asciiVal = aString[0].latin1();  // 0x61

asciiVal = aString[0].latin1();  // 0x61

To copy to clipboard, switch view to plain text mode 

In the latter, an index operation on aString returns a QChar, which as a 'latin1' accessor to the latin1 value (latin1 & ascii the same on the first 128 index range).
