Which property is responsible for pointing the button

If you just want to change the style when you hover the cursor, then you can achieve it with css, just by setting the desired parameter in the pseudo-class :hover .

 .your-class:hover { // some parameters } 

that is, you will need to write styles in a css file and connect it as described here . Then add a style class or identification to the Button .

style.css file

 .my-button:hover { -fx-background-color: green; } 

Here is the java class.

 package styled.button; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.AnchorPane; import javafx.stage.Stage; public class StyledButton extends Application { @Override public void start(Stage primaryStage) throws Exception { AnchorPane anchorPane = new AnchorPane(); anchorPane.getStylesheets() .add(getClass().getResource("/style.css").toExternalForm()); Button button = new Button("Hover Button"); button.getStyleClass().add("my-button"); anchorPane.getChildren().add(button); primaryStage.setScene(new Scene(anchorPane, 400, 600)); primaryStage.show(); } } 

When you hover the cursor, the background of the button changes to green.

or it can be done programmatically:

 package button.hover; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.AnchorPane; import javafx.stage.Stage; public class ButtonHover extends Application { @Override public void start(Stage primaryStage) throws Exception { AnchorPane anchorPane = new AnchorPane(); Button button = new Button("Hover Button"); button.setOnMouseEntered(event -> { button.setStyle("-fx-background-color: green"); }); button.setOnMouseExited(event -> button.setStyle("")); anchorPane.getChildren().add(button); primaryStage.setScene(new Scene(anchorPane, 400, 600)); primaryStage.show(); } }
