Is there a way to remove the default space (padding/margin) that JavaFX label adds? I want to get rid of the space displayed between the black lines on the image below:
Source code:
public class LabelTest extends Application
{
@Override
public void start(final Stage primaryStage)
{
final Group root = new Group();
final Scene scene = new Scene(root, 300, 130, Color.WHITE);
final GridPane gridpane = new GridPane();
gridpane.setPadding(new Insets(5));
gridpane.setHgap(10);
gridpane.setVgap(10);
final Label label = new Label("Label");
label.setStyle("-fx-font-size:44px;-fx-font-weight: bold;-fx-text-fill:#5E34B1;-fx-background-color:#ffc300;");
GridPane.setHalignment(label, HPos.CENTER);
gridpane.add(label, 0, 0);
root.getChildren().add(gridpane);
primaryStage.setScene(scene);
primaryStage.show();
}
}
You can achieve that by adding -fx-padding: -10 0 0 0;
to the list of your styles.
For more flexible solution you can use FontMetrics
information:
FontMetrics metrics = Toolkit.getToolkit().getFontLoader().getFontMetrics(label.getFont());
label.setPadding(new Insets(-metrics.getDescent(), 0, 0, 0));
NB: You need to call that code after scene.show()
. Before that graphics engine is not ready to provide correct metrics.
