public class WebViewBrowser extends Application {
@Override public void start(Stage primaryStage) throws Exception {
Pane root = new WebViewPane();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
double width = screenSize.getWidth();
double height = screenSize.getHeight();
primaryStage.setScene(new Scene(root, width, height));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
public class WebViewPane extends Pane {
public WebViewPane() {
VBox.setVgrow(this, Priority.ALWAYS);
setMaxWidth(Double.MAX_VALUE);
setMaxHeight(Double.MAX_VALUE);
WebView view = new WebView();
view.setMinSize(500, 400);
view.setPrefSize(500, 400);
final WebEngine eng = view.getEngine();
try
eng.load("http://techyadesh.com/video.php");
}
catch(Exception ex)
{
}
GridPane grid = new GridPane();
grid.setVgap(5);
grid.setHgap(5);
GridPane.setConstraints(view, 0, 1, 2, 1, HPos.CENTER, VPos.CENTER, Priority.ALWAYS, Priority.ALWAYS);
grid.getColumnConstraints().addAll(
new ColumnConstraints(100, 100, Double.MAX_VALUE, Priority.ALWAYS, HPos.CENTER, true),
new ColumnConstraints(40, 40, 40, Priority.NEVER, HPos.CENTER, true)
);
// grid.getChildren().addAll(locationField, goButton, view);
grid.getChildren().addAll( view);
getChildren().add(grid);
}
@Override protected void layoutChildren() {
List<Node> managed = getManagedChildren();
double width = getWidth();
double height = getHeight();
double top = getInsets().getTop();
double right = getInsets().getRight();
double left = getInsets().getLeft();
double bottom = getInsets().getBottom();
for (int i = 0; i < managed.size(); i++) {
Node child = managed.get(i);
layoutInArea(child, left, top,
width - left - right, height - top - bottom,
0, Insets.EMPTY, true, true, HPos.CENTER, VPos.CENTER);
}
}
}

It seems to be working fine what you wrote. I tried it on javafx 13 and it just worked. You missed brackets in a couple of places while pasting it in stackoverflow. Other than that I didn't see any mistake. Just upgrade your javafx and it should work.
Here is a working example with your exact code
https://github.com/shashaanktulsyan/java-javafx-maven-learning-tips/tree/master/nu-sharabheshwara-adesh_singh-webview
mvn javafx:run
should simply work.
