Now, if a user enter an invalid data and moves ahead and clicks a button on the Panel, then a dialog pops up and the user have to respond to it. but after that also the button does

问题 I am trying to make an intuitive user interface where the user would enter the numeric values into the JTextFields , advance with the TAB key and finally activate the button to start processing the input. At the beginning the button is disabled and it should be enabled only when all of the data is entered into the text fields. I am using javax.swing.InputVerifier to restrict entering only positive numbers up to 4 decimal places and that works fine. There are 3 focusable objects, two text

问题 What I am trying to do is this, when I enter the details it will validate if the textFiled is empty when a button is pressed, if it is empty it will display a message saying that.

问题 I am attempting to validate the text field user inputs using javax.swing.InputVerifier and the input validation works as expected but I have a problem regarding VerifyInputWhenFocusTarget property. I've made a label to show the status and overridden verify() and shouldYieldFocus() methods of InputVerifier subclass and that works fine.
