[Solved]QLineEdit - Validator doesn't allow to input IP Address
-
I've got this code:
@
ServerIpAddressEdit->setInputMask(QString("000.000.000.000; "));
ServerIpAddressEdit->setValidator( new QRegExpValidator( QRegExp("[0-255].[0-255].[0-255].[0-255]" , Qt::CaseInsensitive), this));
ServerIpPortEdit->setValidator(new QIntValidator(1, 65535, this));
@QRegExpValidator doesn't allow me to input digits into ServerIpAddressEdit(QLineEdit), why?? When I comment this line, everything is okay, but it doesn't validate...
-
In RegExp: \. or even \\. instead just "."
Also [0-255] means different, you may need \d{1,3}, to match 1-3 digits

I don't think you can mix masks and validators for this problem (after 5 long minutes of google search....).
@QString Octet = "(?:[0-1]?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])";
lineEdit->setValidator(new QRegExpValidator(
QRegExp("^" + Octet + "\." + Octet + "\." + Octet + "\." + Octet + "$"), this));@This will work, stoled it from "here":http://lists.trolltech.com/qt-interest/2004-05/thread00085-0.html.
edit:
Or you could do something like "this":http://www.qtcentre.org/threads/6228-Ip-Address-Validation:@ class IP4Validator : public QValidator {
public:
IP4Validator(QObject *parent=0) : QValidator(parent){}
void fixup(QString &input) const {}
State validate(QString &input, int &pos) const {
if(input.isEmpty()) return Acceptable;
QStringList slist = input.split(".");
int s = slist.size();
if(s>4) return Invalid;
bool emptyGroup = false;
for(int i=0;i<s;i++){
bool ok;
if(slist[i].isEmpty()){
emptyGroup = true;
continue;
}
int val = slist[i].toInt(&ok);
if(!ok || val<0 || val>255) return Invalid;
}
if(s<4 || emptyGroup) return Intermediate;
return Acceptable;
}
};@
