Assert problem in line edit

btw, I think you reg exp is not exaclty correct, try to use this one: \d+.

[grsandeep85]

I used QRegExp rx ( "(\\d+)" );

even after that also i m get the message as

Key Press EventATUM
0: 0:123.000:456.000:789.000
1: 1:321.000:654.000:987.000
2: 2:963.000:852.000:741.000
3: 3:357.000:214.000:698.000
resulttemp=::::


Please help me how to proceed further

did you look at Qt Assistant, there is an example in QRegExp::search?

QString str = "offsets: 1.23 .50 71.00 6.00";
        QRegExp rx( "\\d*\\.\\d+" );    // primitive floating point matching
        int count = 0;
        int pos = 0;
        while ( (pos = rx.search(str, pos)) != -1 ) {
            count++;
            pos += rx.matchedLength();
        }
        // pos will be 9, 14, 18 and finally 24; count will end up as 4

QString str = "offsets: 1.23 .50 71.00 6.00";
        QRegExp rx( "\\d*\\.\\d+" );    // primitive floating point matching
        int count = 0;
        int pos = 0;
        while ( (pos = rx.search(str, pos)) != -1 ) {
            count++;
            pos += rx.matchedLength();
        }
        // pos will be 9, 14, 18 and finally 24; count will end up as 4

Here i am not using fixed string,, even i went through the examples also.
The format of the file is as below and user will be writing some more values into the file maximum is 99 points and simultaneously user need to read the values.

Datum X Y Z
0 123 456 789
1 321 654 987
2 345 243 809
......
.....
...... and so on

now i need to search for Datum number i.e., first column only then i need to read the corresponding line split the Datum, X, Y, Z values and store in 3 different variables.

QRegExp rx ( "(\\d+)" );
rx.search ( "Datumno_Val" );

is my code is correct or not.

if it doesn't work then it is not correct.

Then how to proceed further is there any other method to perform this operation.
