How to put a number with loop into checkbox

Hey guys,































































I want all years between 1900 and 2014 into a cbx.































































i tried this but it doesn't work

Java Code:

int year=1900;
while(year<2014)
{
cbxYear.addItem(year + 1);
year = year + 1;
}

Thank you in advance

Oh i found the mistake i had wrote the code into the button :D :)
