How to disable component in Java Swing

[Shaina Na]

Hi friends, I just want to create one Login Form in Java Swing in such a way that when the user make the three wrong input in the User_name or in the Password field then the Login Form automatically block the user input, so that the user can’t able to make input or click on the Submit button. How it can be possible to do this program in Swing, if you guys have any ideas then please let me know. Thanks in Advances

According to my information this is one of the advance features of Java Swing Technology that it provides several inbuilt method for several action. You can make use of ‘void setEnabled(Boolean b);’ method for Disabling and Enabling the Swing Component in Java. This are the method can be evoke by any of the instance of Java Swing Components. The method setEnabled(Boolean b); enable and disable the function of the components based on the parameter passed to these method. If it is ‘true’ then the component is enabled to works and if the parameter is false then the component is disabling to performs. E.g: btn.setEnabled(false); //This will disable the particular component functionality

The java swing has many predefine method that can be used for controlling the behaviors of Swing Components like TextField, TextArea, PasswordField, Button etc. If you wish to gray out the component so that the user can’t interact with that particular component you can make use of the setEnabled(); method and the alternate thing that you can also do is to hide that particular component with the help of setVisisble(); method.
