There is a button in a scene of the main window. When it's clicked, the new window is created, according following code:
public static void create()
{
Stage stage = new Stage();
AnchorPane pane = new AnchorPane();
//Here i add some into pane
stage.setScene(new Scene(pane));
stage.setWidth(500);
stage.setHeight(600);
stage.show();
}
I'd like the main window will remain blocked (i.e. an user won't be able to click on buttons, type text, resize or interact with it with other ways) until the additional window is closed.
Here is a link that shows exactly what you're looking for: http://www.javafxtutorials.com/tutorials/creating-a-pop-up-window-in-javafx/
Here is the main part of the code you need to add:
stage.initModality(Modality.APPLICATION_MODAL);
stage.initOwner(btn1.getScene().getWindow());
stage.showAndWait(); // This forces the program to pay attention ONLY to this popup window until its closed
Hope this helps.

I have a full screen main application stage and want to make a TextInputDialog appear on top, with a modal style (i.e. the dialog must be dismissed before giving other input to the stage).
If I set the owner to the stage, and the style to UTILITY, then it works.
But if I want to remove decoration (by setting the style to UNDECORATED) then the dialog doesn't appear at all! I can only get it to appear by not setting the parent.
If I don't set the parent, the dialog appears on top of the stage but if I click anywhere else on the application it disappears behind the full screen stage.
How do I create an undecorated dialog that has modal-like behaviour over a full-screen stage?
// This works, but is decorated
TextInputDialog dialog = new TextInputDialog();
dialog.initOwner(stage);
dialog.initStyle(StageStyle.UTILITY);
dialog.showAndWait();
// This doesn't show at all (probably appears underneath the stage?)
TextInputDialog dialog = new TextInputDialog();
dialog.initOwner(stage);
dialog.initStyle(StageStyle.UNDECORATED);
dialog.showAndWait();
// This still allows clicking in the stage while dialog shown. Also causes
// "exit" of fullscreen by showing task bar when dialog is shown
TextInputDialog dialog = new TextInputDialog();
dialog.initStyle(StageStyle.UNDECORATED);
dialog.showAndWait();
I've made a complete example, which appears to be something you've tried, but isn't working. In my case it works great though. The window shows full screen, and the dialog comes up in the center without window decorations.
public class DialogCheck extends Application{
public static void main(String[] args){
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("text field");
BorderPane root = new BorderPane();
Button b = new Button("dialog");
root.setCenter(b);
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.setFullScreen(true);
primaryStage.show();
b.setOnAction((evt)->{
TextInputDialog dialog = new TextInputDialog();
dialog.initOwner(primaryStage);
dialog.initStyle(StageStyle.UNDECORATED);
dialog.showAndWait();
});
}
}
Note that this is with java 11 & openjfx 11 on osx.
For some added debugging:
dialog.setOnShown( sevt ->{
System.out.println("showing: " + dialog.isShowing() + ", " + dialog.getX());
TextField field = dialog.getEditor();
field.requestFocus();
System.out.println(field.isFocused());
});
Also note the difference between using 'showAndWait' vs 'show'.
Dialog.showAndWait output:
showing: false, NaN.
false
Dialog.show output:
showing: true, 621.0
true
I'm currently trying to show a BorderPane inside my AnchorPane (that is also inside my StackPane). I tried to show a new Scene but it show me 2 items in my Windows taskbar, and this is not really what I want.
For exemple, when you open the Preference in Eclipse, u get another window that is not visible in the taskbar.
So basically, the only thing I need is a window that looks like an ImageView, like anchored in the AnchorPane , not resizable and undecorated.
Expected result at end
This is what I tried:
btnDice.setOnAction(new EventHandler<ActionEvent>()
{
#Override
public void handle(ActionEvent arg0) {
Scene newScene = new Scene(new BorderPane(), 230, 100);
Stage newWindow = new Stage();
newWindow.setScene(newScene);
newWindow.show();
}
});
Have an issue with JavaFX where whenI popup a new stage, that new window will take focus from any windows application with current focus
I want it to popup to the front, but not take focus, so if the user was typing elsewhere they can continue to type etc.
In Swing you could get around this by:
dialog.setFocusable(false);
dialog.setVisible(true);
dialog.setFocusable(true);
There seems to be no similar option in JavaFx.
Example below, when you click the button it will popup a new stage, taking focus (note I don't want to request focus back, as in the real application the user could be writing an email or on a web page when the popup happens, it needs to not take focus from these activities)
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
public class Main extends Application {
private Stage stage;
#Override public void start(Stage stage) {
this.stage = stage;
stage.setTitle("Main Stage");
stage.setWidth(500);
stage.setHeight(500);
Button btnPopupStage = new Button("Click");
btnPopupStage.setOnMouseClicked(event -> popupStage());
Scene scene = new Scene(btnPopupStage);
stage.setScene(scene);
stage.show();
}
private void popupStage(){
Stage subStage = new Stage();
subStage.setTitle("Sub Stage");
subStage.setWidth(250);
subStage.setHeight(250);
subStage.initOwner(stage);
subStage.show();
System.out.println("Does main stage have focus : "+stage.isFocused());
System.out.println("Does popup have focus : "+subStage.isFocused());
}
public static void main(String[] args) {
launch(args);
}
}
Any ideas for a stage to not take focus on a stage.show() ? Thanks
Just incase anyone is is searching, I couldn't find a solution, but I found someone with the same issue who raised a ticket for the openjdk
https://bugs.openjdk.java.net/browse/JDK-8090742
To get around it unfortunately I put the JavaFX pane inside a Swing JFrame and just called
dialog.setFocusableWindowState(false);
dialog.setVisible(true);
dialog.setFocusableWindowState(true);
Which has fixed the focus stealing issue, but not sure on the effects of having JFx in a Swing JFrame.
If anyone finds a non focus stealing way of a new Window in JFx let me know.
Thanks
to prevent what you are describing by assuming is the cause of your problem then you need to add subStage.initModality(Modality.NONE); . But that is not the problem, actually there is no problem here look here
stage.setWidth(500); // your stage is 500 wide
stage.setHeight(500); // & 500 long
Scene scene = new Scene(btnPopupStage);// your scene has a parent which is button
//by inheritance if i should say your button is 500 wide & long.
Have you seen the problem? your button will always respond to click events which in event will create a new Stage hence give focus to that Stage
I'm having difficulty finding out if this is even possible. The common behavior that most people want is to fade out an extension of a node, which is entirely possible through a FadeTransition
However, I'm trying to fade out an entire stage, so imagine closing the running program and instead of simply killing the windows (i.e. showing -> not showing), I would like the window (stage) to fade out over 2 seconds like a toast or notification would.
Create a timeline with a KeyFrame that changes the opacity of the stage's scene's root node. Also make sure to set the Stage style and the scene fill to transparent. Then make the program exit once the timeline is finished.
Below is an application with a single big button that, when clicked, will take 2 seconds to fade away, and then the program will close.
public class StageFadeExample extends Application {
#Override
public void start(Stage arg0) throws Exception {
Stage stage = new Stage();
stage.initStyle(StageStyle.TRANSPARENT); //Removes window decorations
Button close = new Button("Fade away");
close.setOnAction((actionEvent) -> {
Timeline timeline = new Timeline();
KeyFrame key = new KeyFrame(Duration.millis(2000),
new KeyValue (stage.getScene().getRoot().opacityProperty(), 0));
timeline.getKeyFrames().add(key);
timeline.setOnFinished((ae) -> System.exit(1));
timeline.play();
});
Scene scene = new Scene(close, 300, 300);
scene.setFill(Color.TRANSPARENT); //Makes scene background transparent
stage.setScene(scene);
stage.show();
}
public static void main (String[] args) {
launch();
}
}
i have a question about using virtual keyboard on touch supported pc with Windows 8.1. I have managed to show the virtual keyboard when textfield is focused with java switch:
-Dcom.sun.javafx.isEmbedded=true -Dcom.sun.javafx.virtualKeyboard=javafx
I found how to that on JavaFX Virtual Keyboard doesn't show1.
But when the keyboard show's up, it overlapps nodes below the keyboard.
According to what I read, http://docs.oracle.com/javase/8/javafx/user-interface-tutorial/embed.htm, it should't be working like that.
Does anyone have any experience with that kind of problem?
When i run the test application it shows in full screen and embedded virtual keyboard is showing, becasue the textfield has focus. The textfield in this case is not visible until i "hide" the keyboard. I am not sure that this is the right approach so i need help please.
java -Dcom.sun.javafx.isEmbedded=true -Dcom.sun.javafx.virtualKeyboard=javafx application.TestVKB
public class TestVKB extends Application{
public static void main(String[] args) {
Application.launch(args);
}
#Override
public void start(Stage stage) throws Exception {
TextField tfComment = new TextField();
tfComment.setPromptText("Enter comment");
BorderPane borderPane = new BorderPane();
borderPane.setBottom(tfComment);
Scene scene = new Scene(borderPane);
stage.setScene(scene);
stage.setMaximized(true);
stage.show();
}
}
After click in field username or password
I would be grateful for any advice. Thanks in advance.
As I've already pointed out in my first answer, the virtual keyboard is embedded in a PopupWindow, created in a different stage, and displayed on top of your current stage.
The option -Dcom.sun.javafx.vk.adjustwindow=true works, moving the main stage so the control is visible and there is no overlapping.
But when this input control is located at the bottom of the main stage, this is moved up to the center of the screen leaving a big empty gap that shows whatever is behind.
This second answer gives a solution to move the main stage just the required distance, without any gap, also taking into account the fade in/out animations of the virtual keyboard.
For starters, in our scene, we add a Button on the center, and the TextField on the bottom. With two controls we can change the focus easily and show/hide the keyboard.
To maximize the stage I'll use getVisualBounds(), so the taskbar can be visible.
private PopupWindow keyboard;
private final Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
private final Rectangle2D bounds = Screen.getPrimary().getBounds();
private final double taskbarHeight=bounds.getHeight()-visualBounds.getHeight();
#Override
public void start(Stage stage) {
TextField tfComment = new TextField();
tfComment.setPromptText("Enter comment");
BorderPane borderPane = new BorderPane(new Button("Click"));
borderPane.setBottom(tfComment);
Scene scene = new Scene(borderPane);
stage.setScene(scene);
stage.setX(visualBounds.getMinX());
stage.setY(visualBounds.getMinY());
stage.setWidth(visualBounds.getWidth());
stage.setHeight(visualBounds.getHeight());
stage.show();
}
We need to find the new stage when it's shown. In the same way as Scenic View, we'll use a deprecated method to get a valid window:
private PopupWindow getPopupWindow() {
#SuppressWarnings("deprecation")
final Iterator<Window> windows = Window.impl_getWindows();
while (windows.hasNext()) {
final Window window = windows.next();
if (window instanceof PopupWindow) {
if(window.getScene()!=null && window.getScene().getRoot()!=null){
Parent root = window.getScene().getRoot();
if(root.getChildrenUnmodifiable().size()>0){
Node popup = root.getChildrenUnmodifiable().get(0);
if(popup.lookup(".fxvk")!=null){
return (PopupWindow)window;
}
}
}
return null;
}
}
return null;
}
We'll call this method when the textfield gets the focus:
...
stage.show();
tfComment.focusedProperty().addListener((ob,b,b1)->{
if(keyboard==null){
keyboard=getPopupWindow();
}
});
}
Once we have the window, we can listen to changes in its position and move the main stage accordingly:
....
stage.show();
//findWindowExecutor.execute(new WindowTask());
tfComment.focusedProperty().addListener((ob,b,b1)->{
if(keyboard==null){
keyboard=getPopupWindow();
keyboard.yProperty().addListener(obs->{
System.out.println("wi "+keyboard.getY());
Platform.runLater(()->{
double y = bounds.getHeight()-taskbarHeight-keyboard.getY();
stage.setY(y>0?-y:0);
});
});
}
});
}
Note that instead of moving up the stage, another option will be resizing it (if there is enough space within the controls).
This will be the case where the textfield gets the focus and the virtual keyboard is fully shown:
Basically, the virtual keyboard is embedded in a PopupWindow, created in a different stage, and displayed on top of your current stage, at the bottom of the screen, no matter where the InputControl that triggers the keyboard is located.
You can see that on the FXVKSkin class:
winY.set(screenBounds.getHeight() - VK_HEIGHT);
But, just inmediately after that, you can find this:
if (vkAdjustWindow) {
adjustWindowPosition(attachedNode);
}
So, there's another command line option that you can use to move the stage so the node (the textfield in this case) will be on the center of the screen and you can type without overlapping it:
-Dcom.sun.javafx.vk.adjustwindow=true
Note that when the textfield loses the focus, the keyboard is hidden and the stage is moved again to its original position:
restoreWindowPosition(oldNode);
I've tested this option successfully, but when you have the textfield at the bottom of the screen, this will move your stage bottom to the center of the screen, leaving a big gap between both stages (you'll see whatever you have on the background).
I've managed to add a listener to the new stage and adjust the position just the necessary. If you are interested I could post it.
EDIT
Note this command line option won't work if the stage is maximized. A simple solution for this is:
Rectangle2D bounds = Screen.getPrimary().getBounds();
stage.setX(bounds.getMinX());
stage.setY(bounds.getMinY());
stage.setWidth(bounds.getWidth());
stage.setHeight(bounds.getHeight());
stage.show();
I liked the solution, but in my case I prefer to move the keyboard using the showed method getPopupWindow i created a listener on textfield and changed the position of the keyboard directly.
textField.focusedProperty().addListener((ob, b, b1) -> {
if (keyboard == null) {
keyboard = getPopupWindow();
keyboard.setHideOnEscape(Boolean.TRUE);
keyboard.setAutoHide(Boolean.TRUE);
keyboard.centerOnScreen();
keyboard.requestFocus();
keyboard.sizeToScene();
}
Platform.runLater(() -> {
keyboard.setY(**NEW_POSITION_OF_KEYBOARD**);
});
});
