Apache Pivot Label

//Create a new Apache Pivot Label
Label label = new Label();

//Set the Font:
label.getStyles().put(“font”, new Font(“Verdana”, Font.BOLD, 24);

//Set Text Color
label.getStyles().put(“color”, Color.WHITE);

//Set Horizontal Alignment of the Text within the Label.
//Options include: LEFT, RIGHT, CENTER
label.getStyles().put(“horizontalAlignment”, HorizontalAlignment.CENTER);

//Set Vertical Alignment of the Text within the Label.
//Options include: TOP, BOTTOM, CENTER
label.getStyles().put(“verticalAlignment”, VerticalAlignment.CENTER);

//Set the Background color
label.getStyles().put(“backgroundColor”, Color.RED);

//Set the Padding on all four sides (top, right, bottom, left) to 
//same number of pixels. In next line = 10 pixels.
label.getStyles().put(“padding”, 10);

//Set the Padding on each side specifically:
label.getStyles().put(“padding”, “{top:5, left:15, bottom:25, right:35}”);
