I want to set full screen Anchor Pane with title Bar in JavaFX. I used the property
stage.setFullScreen(true);
but it does not show title bar. What should I do to make my Anchor Pane full screen but with title bar?
After using setMaximized(true); clean and build your project.
public class Test extends Application {
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("DashBoard.fxml"));
stage.getIcons().add(new Image("/com/images/icon.png"));
Scene scene = new Scene(root);
stage.setTitle("Dash Board");
stage.setMaximized(true);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}

I want to show live streaming video from url in javafx. I am using webview.
It is showing only text in that webpage. It is not showing live video streaming. Please suggest me a way to do that.
public class A extends Application {
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
WebView webView = new WebView();
webView.getEngine().load("http://192.168.0.143:8000/");
VBox vbox = new VBox(webView);
Scene scene = new Scene(vbox);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
Please refer to the JavaFX SSCCE below. The print statement appears when closing the primary stage from the window's default titlebar "X" button. The print statement does NOT appear when clicking the "Close" button. Why isn't my onCloseHandler being called when I call close() on the stage? Is my expectation somehow unreasonable or is this (yet another) bug in JavaFX? Thanks!
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
Button closeButton = new Button("Close");
closeButton.setOnAction(e -> {
primaryStage.close();
});
primaryStage.setOnCloseRequest(e -> {
System.out.println("onCloseRequest handler called!");
});
StackPane rootPane = new StackPane();
rootPane.getChildren().add(closeButton);
primaryStage.setScene(new Scene(rootPane, 300, 250));
primaryStage.show();
}
}
As described by the Javadoc, this is only fired on external requests:
Called when there is an external request to close this Window.
Maybe setOnHidden would work for you, it is called in both cases.
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
Button closeButton = new Button("Close");
closeButton.setOnAction(e -> {
primaryStage.close();
});
primaryStage.setOnHidden(e -> {
System.out.println("stage hidden");
});
StackPane rootPane = new StackPane();
rootPane.getChildren().add(closeButton);
primaryStage.setScene(new Scene(rootPane, 300, 250));
primaryStage.show();
}
}
I have a TableView. If it has columns, I can add context menus to the columns, and the menu will appear when I right click on the column header.
How do I add a context menu to the blank bar that appears for an empty table? Screenshot:
This can be done by accessing the internal structure of the TableView directly, I'm unaware of any official API to do this.
The official TableView CSS names a class of column-header-background which we can then access via the Node#lookup() method.
An example
public class ContextMenuOnTableHeader extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
TableView<String> table = new TableView<>();
Scene scene = new Scene(table);
primaryStage.setScene(scene);
primaryStage.setWidth(200);
primaryStage.setHeight(200);
primaryStage.show();
Node header = table.lookup(".column-header-background");
header.setOnContextMenuRequested(event -> {
ContextMenu menu = new ContextMenu();
menu.getItems().add(new MenuItem("Mr Horse"));
menu.show(header, event.getScreenX(), event.getScreenY());
});
}
}
I created a scene in class1, then i created a scene2 in class2.
How to switch between them?
public class class1 extends Application{
Stage window1;
BorderPane layout1;
Scene scene1;
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
window1 = primaryStage;
window.setTitle("Stage 1");
// And here is a button which switchs between scenes or stages,
//i dont know what is better.So:
button.setOnAction(e -> ?????????)
scene1 = new Scene(layout1, 800,600);
window1.show();
}
}
And here is the second class in which i have another scene.
public class class2 extends Application{
Stage window2;
BorderPane layout2;
Scene scene2;
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
window2 = primaryStage;
window2.setTitle("Stage 2");
scene2 = new Scene(layout, 800,600);
window2.show();
}
}
I wrote this controller to keep track of the different scenegraphes and switch the content of my Stage with no hassle.
Maybe you want to take a look at FXML:
http://docs.oracle.com/javafx/2/fxml_get_started/why_use_fxml.htm#CHDCHIBE
public class ScreenController {
private HashMap<String, Pane> screenMap = new HashMap<>();
private Scene main;
public ScreenController(Scene main) {
this.main = main;
}
protected void addScreen(String name, Pane pane){
screenMap.put(name, pane);
}
protected void removeScreen(String name){
screenMap.remove(name);
}
protected void activate(String name){
main.setRoot( screenMap.get(name) );
}
}
So I can write:
ScreenController screenController = new ScreenController(scene);
screenController.add("layout1", layout1 );
screenController.add("layout2", layout2 );
screenController.add("testSwitch", FXMLLoader.load(getClass().getResource( "TestSwitch.fxml" )));
button.setOnAction(e -> screenController.activate("layout2"));
This was a workaround for a fullscreen application, where the MacOS fullscreen transition was shown every time a stage switches its scene.
put this in your Controller. You can use anything (like button,label etc.) to get access to your Stage (best inside an eventhandler from Button).
Stage stage = (Stage) AnyThingOnScene.getScene().getWindow();
Parent root = FXMLLoader.load(getClass().getResource("someFile.fxml"));
Scene scene = new Scene(root,420,360);
stage.setScene(scene);
When a parent component has transparent mouse enabled all child controls are no longer able to receive mouse events. Is it possible exclude a child from this rule.
public class TransparentMouseTest extends Application
{
public static void main(String[] args)
{
Application.launch(args);
}
#Override
public void start(Stage stage)
{
Pane root = new StackPane();
root.getChildren().add(new TextField());
Pane p = new StackPane();
p.setMouseTransparent(true);
p.setStyle("-fx-background-color:#F001;");
p.getChildren().add(new Button("Button should be able \nto receive mouse events."));
root.getChildren().add(p);
Scene scene = new Scene(root, 400, 300);
stage.setScene(scene);
stage.show();
}
}
