How do I send a value without press enter on Matlab GUI?

I'm making a Graphical Interface on Matlab GUI, that I set a number and get an answer. But, when I set the number, I always have to press <enter> to get the answer.

I'd like to know how do I set the number and automatically get the answer, like an "automatic enter".

You could set the edit-callback (if the feature has one) but you'll still need to press enter or tab so the GUI knows you're done editing the text.

It is possible if you use a drop down list or a popup menu. Every selection can captured using its callback.
