Adding Text. To add a text object to your application, use any of the constructors shown in Example 1 through Example 3. Text t = new Text (10, 20, "This is a text sample"); You can also create text objects by using the javafx.
Text Input Dialog Example TextInputDialog extends Dialog<String> class – note the Dialog 's type is String and the result Optional 's type is always a String . From the Text Input Dialog window: Click the Get Text button to show a text input dialog. Enter some text in the text input field. Click OK or Cancel.
Introduction to JavaFX API. In order to build rich client applications, a library known as JavaFX is used which offers an API for creating, testing, debugging and deploying GUI applications that run on nearly all devices that have the support of Java. That is, it operates in a consistent manner across all platforms.
getInput() displays a dialog and calls wait. When the ok button is pressed on the dialog, the dialog sets the user input in a member variable and calls notify. When notify is called, getInput() continues and returns the member variable.
Use an Alert:
Alert errorAlert = new Alert(AlertType.ERROR);
errorAlert.setHeaderText("Input not valid");
errorAlert.setContentText("The size of First Name must be between 2 and 25 characters");
errorAlert.showAndWait();
