    <p>Below is a sample code. Where it loads 6 Images and displays them in a screen. Each Image size is of 2.3 MB. So on loading each Image, I should see a rise of memory consumption of 3 MB approx for each Image loaded. But it turns out that it loads 10 MB for each Image.</p> <pre><code>import java.io.File; import java.io.FileInputStream; import java.io.InputStream; import javafx.application.Application; import javafx.geometry.Orientation; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.ScrollBar; import javafx.scene.image.Image; import javafx.scene.image.ImageView; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class Test extends Application { public static void main(String... args) { launch(args); } @Override public void start(Stage primaryStage) throws Exception { ScrollBar bar = new ScrollBar(); bar.setOrientation(Orientation.VERTICAL); final VBox box = new VBox(); Group root = new Group(); root.getChildren().addAll(box, bar); Scene scene = new Scene(root); primaryStage.setScene(scene); primaryStage.setTitle("Layout Sample"); primaryStage.show(); for (int ik = 0; ik &lt; 6; ik++) { System.out.println("1"); ImageView i = new ImageView(); InputStream is = new FileInputStream(new File("C:\\Users\\Jatin\\Documents\\BarcodeNew\\w.png")); Image im = new Image(is); i.setImage(im); box.getChildren().add(i); is.close(); } //r.close(); } } </code></pre> <p>In my application it is turning out that, a 1.3MB Image is taking 50 MB space. Any reasons?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
