Which UI control and API are you referring to?
I cannot seem to find a setValidator() method in the
*com.google.gwt.user.client.ui.TextBox
*class heirarchy.
You might want to use the
Interface HasValueChangeHandlers
to add a handler that will be able to parse it via Integer.getInteger(
myControl.g
but how i do this ?

Every control has a number of xxxHandlers interfaces that you can hang code
off of.
Try something like this using old style (pre-binder) code
// create a text box & add it to a Panel
myTextBox = new TextBox();
// add a handler to the text box control
myTextBox.addValueChangeHandler( new ValueChang
hmm, i understand that part, but how i put the values? inside the
OnValueChange?
Regards! :D

Yes, your custom onValueChange() code will be called when the value of the
textbox changes.
Do with it what you will...
If that doesn't quite work for your purposes, there is a handler for most UI
events like
addDoubleClickHandler( new DoubleClickHandler() onDoubleClick()... )
They are listed
