I have TitledPane, which i want to hide back (after expanding - un-expand it) after pressing a button. Is there any way to do it? I didn't find any way :( Thanks!
Just do
titledPane.setExpanded(false);
Complete example:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TitledPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class TitledPaneExample extends Application {
#Override
public void start(Stage primaryStage) {
Label label = new Label("Some content");
Button button = new Button("OK");
VBox content = new VBox(10, label, button);
TitledPane titledPane = new TitledPane("Titled Pane", content);
button.setOnAction(e -> titledPane.setExpanded(false));
VBox root = new VBox(titledPane);
Scene scene = new Scene(root, 250, 400);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}

How to do that in JavaFX?
The popup shows up when the mouse enters a node. When the mouse enters the showing popup, the popup obscures the mouse from the node. Then the node fire exit event. How to make the popup ignore the mouse events?
code
package sample;
import javafx.application.Application;
import javafx.geometry.Point3D;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Popup;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
primaryStage.setScene(new Scene(root, 300, 275));
Label labelNode = new Label("Label Node");
labelNode.setPrefHeight(200);
labelNode.styleProperty().set("-fx-background-color: orange");
Popup popup = new Popup();
popup.getScene().getRoot().setMouseTransparent(true);
AnchorPane popContent =new AnchorPane();
popContent.styleProperty().set("-fx-background-color: red");
popContent.setPrefHeight(100);
popContent.getChildren().add(new Label("Popup content"));
popup.getContent().add(popContent);
labelNode.setOnMouseEntered(event->{
Point3D point3D = labelNode.localToScene(event.getX(), event.getY(), 0);
popup.show(primaryStage, point3D.getX()-5, point3D.getY()-5);
});
labelNode.setOnMouseExited(event->{
popup.hide();
});
root.getChildren().add(labelNode);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Please try moving the cursor in to "yellow" several times.
Solution:
Keep two boolean nodeExited and popupExited statuses. Hide popup when both are true.
package sample;
import javafx.application.Application;
import javafx.geometry.Point3D;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Popup;
import javafx.stage.Stage;
public class Main extends Application {
boolean nodeExited = false;
boolean popupExited = false;
#Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
primaryStage.setScene(new Scene(root, 300, 275));
Label labelNode = new Label("Label Node");
labelNode.setPrefHeight(200);
labelNode.styleProperty().set("-fx-background-color: orange");
Popup popup = new Popup();
popup.getScene().getRoot().setMouseTransparent(true);
AnchorPane popContent = new AnchorPane();
popContent.styleProperty().set("-fx-background-color: red");
popContent.setPrefHeight(100);
popContent.getChildren().add(new Label("Popup content"));
popup.getContent().add(popContent);
popup.getScene().setOnMouseEntered(event -> {
popupExited = false;
});
popup.getScene().setOnMouseExited(event -> {
popupExited = true;
if (nodeExited)
popup.hide();
});
labelNode.setOnMouseEntered(event -> {
nodeExited = false;
Point3D point3D = labelNode.localToScene(event.getX(), event.getY(), 0);
popup.show(primaryStage, point3D.getX() - 5, point3D.getY() - 5);
});
labelNode.setOnMouseExited(event -> {
nodeExited = true;
if (popupExited)
popup.hide();
});
root.getChildren().add(labelNode);
primaryStage.show();
}

launch(args);
}
}
Since IntelliJ version 2019.2 Jetbrains removed the titlebar from the IDE and put the minimize, maximize and close button of the window into the menubar. So far, I have not found out how to do so using javafx. Is there a way to instanciate a "WindowControlButtons"-Class, so I can easily add them to the menubar or do I have to add a buttongroup and style the buttons for each platform myself?
Example how it shall look like on Windows:
As suggested by #mr mcwolf You can try below solution.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Priority;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
public class JavaFXApplication1 extends Application {
#Override
public void start(Stage primaryStage) {
Button closeButton = new Button();
closeButton.setText("X");
closeButton.setOnAction((ActionEvent event) -> {
javafx.application.Platform.exit();
});
Button hideButton = new Button();
hideButton.setText("-");
hideButton.setOnAction((ActionEvent event) -> {
primaryStage.setIconified(true);
});
Menu menu = new Menu("Menu");
MenuItem menuItem1 = new MenuItem("item 1");
MenuItem menuItem2 = new MenuItem("item 2");
menu.getItems().add(menuItem1);
menu.getItems().add(menuItem2);
MenuBar menuBar = new MenuBar();
menuBar.getMenus().add(menu);
HBox hBox = new HBox(menuBar, hideButton, closeButton);
HBox.setHgrow(menuBar, Priority.ALWAYS);
HBox.setHgrow(hideButton, Priority.NEVER);
HBox.setHgrow(closeButton, Priority.NEVER);
BorderPane root = new BorderPane();
root.setTop(hBox);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.initStyle(StageStyle.UNDECORATED);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Output on Windows looks like this.
I know that I can set cursor type for the entire scene using Scene.setCursor method. But if I swap the scene with another one, cursor always resets to default - disregarding the cursor set on new scene. Here's the test case, tested in XFCE and XMonad:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Cursor;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class HideCursor extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
StackPane root = new StackPane();
root.setStyle("-fx-background-color: green");
Scene scene = new Scene(root, 600, 600);
scene.setCursor(Cursor.MOVE);
StackPane root2 = new StackPane();
root2.setStyle("-fx-background-color: blue");
Scene scene2 = new Scene(root2, 600, 600);
scene2.setCursor(Cursor.MOVE);
primaryStage.setScene(scene);
Button switchScene = new Button("switch");
root.getChildren().add(switchScene);
switchScene.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
primaryStage.setScene(scene2);
}
});
primaryStage.show();
}
}
Interestingly, in Windows 7 it works as expected. What am I doing wrong?
In Javafx the DisclosureNode of Treeview is on left by default. How can I I place the Disclosure Node to Right (float right)..??
Any Help would be appreciated.
You only need to set the Node Orientation to get a right to left behaviour. But be aware of, that all childrens of this TreeView will inherit the orientation as a default.
import javafx.application.Application;
import javafx.geometry.NodeOrientation;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class TreeViewRightLeft extends Application {
#Override
public void start(Stage primaryStage) {
TreeItem<String> item = new TreeItem<>("Root Node");
item.setExpanded(true);
item.getChildren().addAll(
new TreeItem<>("Item 1"),
new TreeItem<>("Item 2"),
new TreeItem<>("Item 3")
);
TreeView<String> treeView = new TreeView<>(item);
// Here you can select the orientation.
treeView.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
BorderPane root = new BorderPane(treeView);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("TreeView");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}

I have a Label with an image and text
final Label label = new Label(labelText);
label.setTextAlignment(TextAlignment.CENTER);
ImageView livePerformIcon = new ImageView(MainApp.class.getResource("/images/Folder-icon.png").toExternalForm());
label.setGraphic(livePerformIcon);
I get this as a visual result:
How I can change the text position? I want to set the text below the Image?
label.setContentDisplay(ContentDisplay.TOP);
Play with this to see the effect of the different alignment settings:
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.control.ContentDisplay;
import javafx.scene.control.Label;
import javafx.scene.image.ImageView;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.GridPane;
import javafx.scene.text.TextAlignment;
import javafx.stage.Stage;
public class LabelGraphicAlignmentTest extends Application {
#Override
public void start(Stage primaryStage) {
BorderPane root = new BorderPane();
Label label = new Label("Some\ntext");
label.setGraphic(new ImageView(getClass().getResource("/images/Folder-icon.png").toExternalForm()));
label.setMaxWidth(Double.POSITIVE_INFINITY);
label.setMaxHeight(Double.POSITIVE_INFINITY);
label.setStyle("-fx-border-color: blue;");
root.setCenter(label);
ComboBox<ContentDisplay> contentDisplayBox = new ComboBox<>();
contentDisplayBox.getItems().addAll(ContentDisplay.values());
contentDisplayBox.getSelectionModel().select(ContentDisplay.LEFT);
label.contentDisplayProperty().bind(contentDisplayBox.valueProperty());
ComboBox<Pos> alignmentBox = new ComboBox<>();
alignmentBox.getItems().addAll(Pos.values());
alignmentBox.getSelectionModel().select(Pos.CENTER);
label.alignmentProperty().bind(alignmentBox.valueProperty());
ComboBox<TextAlignment> textAlignmentBox = new ComboBox<>();
textAlignmentBox.getItems().addAll(TextAlignment.values());
textAlignmentBox.getSelectionModel().select(TextAlignment.LEFT);
label.textAlignmentProperty().bind(textAlignmentBox.valueProperty());
GridPane ctrls = new GridPane();
ctrls.setHgap(5);
ctrls.setVgap(5);
ctrls.setPadding(new Insets(10));
ctrls.addRow(0, new Label("Content display:"), new Label("Alignment:"), new Label("Text Alignment:"));
ctrls.addRow(1, contentDisplayBox, alignmentBox, textAlignmentBox);
root.setTop(ctrls);
Scene scene = new Scene(root, 600, 250);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I had to center the text of a label which acted like a title. The following code snippet did the trick.
final Label title = new Label("Some text");
title.setMaxWidth(Double.MAX_VALUE);
title.setAlignment(Pos.CENTER);
Good programming :-)
I was able to grab the button from the fxml file:
#FXML Label countDownClockLabel;
Then when the controller was initialized i set the text position:
#FXML
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
countDownClockLabel.setAlignment(Pos.CENTER);
}
You have to import:
import javafx.geometry.Pos;
