QRegExp: Last sign has to be a number

[forenued]

Hello,

i need a regular expression that ensures that the last sign in a QString is a digit and i tried the following code:

QRegExp rx ("[0-9]$");
 
cout << rx.exactMatch("123") << endl;

QRegExp rx ("[0-9]$");

cout << rx.exactMatch("123") << endl;

To copy to clipboard, switch view to plain text mode 

i always get false as result, but i don't understand why?

Can anybody tell me what i'm doing wrong?

Thank you very much!

Can't test but I think this should work:

QRegExp rx (".*[0-9]$");

QRegExp rx (".*[0-9]$");

To copy to clipboard, switch view to plain text mode 

Your regexp should match this:

cout << rx.exactMatch("3") << endl;

cout << rx.exactMatch("3") << endl;

To copy to clipboard, switch view to plain text mode 

Does this match?
If so, [0-9]$ machtes one and only one digit (exactMatch)
[0-9] can be written as \d as well, just follow the link to QRegExp
