Reading integers in a GTK textbox...


Hi...

i have problems to validate the data that i read in a GTK textbox...

i was using the g_strtod() function to convert from human entered strings to decimals but when you enter a word that function returns a zero.... i dont know how to validate... becuase, zero is a valid value.

if you enter numbers with alphabetic chars it cuts up and returns the numbers only...i.e.:

input: 123sg, output 123

any idea on how to convert in a good way the data entered????

Thank you.

if the nptr == endptr then you know that nothing was converted, so a word will still return 0, but having nptr==endptr will mean that the value is not zero.
