What is the best widget to use to retrieve doubles or integers from the user on the screen?
I am at a loss to figure out how to the get the data in order to manipulate it later in calculations.
For example:
int num1;
int num2;

int sum = num1 + num2

if I was in a console application I would use cin to get the data from the user. How do I do that in the GUI environment through a form?
