Re: check if qstring is number

from the docs you'll find many conversion routines in the QString class (toInt, toFloat, toXXX etc)

Re: check if qstring is number

... but to answer your actual question you can actually use the return value to check...


QString s = "your text here";

bool isNum;

int value = s.toInt(&isNum);

if (isNum)
   // use returned value
   // report error

 Not tested but should work. Smiley Happy
