JavaFX: Label widget

Label widget is used to define non-editable text control.

 

Can a label has event handlers?

No

 

Label class provides following constructors to get an instance.

 

public Label()

public Label(String text)

public Label(String text, Node graphic)

'text' specifies the text to be displayed in the label.

 

How to set a font to the label?

label1.setFont(Font.font("Verdana", FontPosture.REGULAR, 45));

 

How to set alignment?

label3.setAlignment(Pos.TOP_LEFT);

 

How to add image to label?

Using ‘setGraphic’ method, you can set graphic icon to the label.

 

String filename = "javaIcon.png";

InputStream in = this.getClass().getClassLoader().getResourceAsStream(filename);

Image image = new Image(in);

ImageView imageView = new ImageView(image);

 

label7.setGraphic(imageView);
