Can you please tell me, how can I make a pane scrollable? I am able to make an image scrollable, like this:
VBox root = new VBox();
ScrollPane sp = new ScrollPane();
sp.setContent(new ImageView(new Image(getClass().getResourceAsStream("test.png"))));
root.getChildren().add(sp);
But when I am trying to make a whole pane scrollable, which consists of some Buttons and a small animation, there happens nothing regarding scrollbars. There are no scrollbars. How can I solve that?
Thank you in advance.
I tried to do it by myself, and it is because your scroll pane has fixed width and height, by resizing window, your scroll pane doesn't resize on itself. You can use anchor pane so scroll pane will resize with anchor pane. You could do something like this:
ImageView image = new ImageView(new Image("wp1951596.jpg"));
ScrollPane scrollPane = new ScrollPane();
scrollPane.setContent(image);
scrollPane.setPrefSize(400, 400);
AnchorPane.setTopAnchor(scrollPane, 0.);
AnchorPane.setRightAnchor(scrollPane, 0.);
AnchorPane.setBottomAnchor(scrollPane, 0.);
AnchorPane.setLeftAnchor(scrollPane, 0.);
rootPane.getChildren().add(scrollPane);
I would also recommend you using JavaFX with .fxml files. Then you can create your layout in SceneBuilder and it will make everything easier and faster.

I'am not familiar with JavaFx so I'am trying to code my JavaFx Components in Java Controller classes and calling them in main, my problem is that I cant size my layouts with all the width of the the window, I have this simple code :
public Acceuil(){
LAB_POST = new Button("Posts");
LAB_EVENT = new Button("Evennements");
.....
// my two boxes
VBox leftPane = new VBox();
FlowPane bpane = new FlowPane();
leftPane.setPadding(new Insets(20));
leftPane.setSpacing(30);
leftPane.setAlignment(Pos.CENTER);
leftPane.setStyle("-fx-background-color:#34495e");
leftPane.setMinWidth(300);
leftPane.setPrefSize(300, 600);
bpane.setStyle("-fx-background-color: red;"); // to see the space that it took
bpane.setMaxWidth(Double.MAX_VALUE);
bpane.setMaxWidth(Double.MAX_VALUE);
bpane.setMaxWidth(Double.MAX_VALUE);
bpane.setMaxWidth(Double.MAX_VALUE);
leftPane.getChildren().addAll(TXT_SEARCH, LAB_POST....);
this.getChildren().addAll(leftPane,bpane);
this.setMinHeight(600);
this.setMinWidth(900);
}
(Ps: I tried the FlowPane,BorderPane,AnchorPane and even Boxes)
So I'am Expecting to have the bpane in all the space that remains in my window but I get this,
So I'am wondering what I need to type to let the bpane take all the space, Thank you
I agree with Sedrick we need to know what is the container of these elements but you can try this:
bpane.setStyle("-fx-background-color: red;");
HBox.setHgrow(bpane, Priority.ALWAYS); // Add this line
Also if it is inside an AnchorPane you can try this:
AnchorPane.setTopAnchor(this, 0.0);
AnchorPane.setRightAnchor(this, 0.0);
AnchorPane.setBottomAnchor(this, 0.0);
AnchorPane.setLeftAnchor(this, 0.0);
I want add white border around ImageView.
One solution is to wrap the images in a Button.
And I try use StackPane:
StackPane stackPaneforImageActivity = new StackPane();
Image activityImage = new Image(file.toURI().toString());
ImageView imv = new ImageView(activityImage);
newActivityHBox.getChildren().add(stackPaneforImageActivity);
stackPaneforImageActivity.getChildren().add(imv);
stackPaneforImageActivity.setPadding(new Insets(10));
stackPaneforImageActivity.setStyle("-fx-border-color:white;-fx-background-color: black;");
imv.setFitHeight(30);
imv.setFitWidth(30);
But
Are there other solutions?
But the image is outside the StackPane. Why?
Hi I'm trying to create a simple layout that looks like this using JavaFX.
I would like the user to be able to drag/resize the middle bar. I've tried to make this using a GridPane. But I can't figure out how to get the middle resized. Perhaps GridPane is not the way to go. Both panes will contain a lot of other program code later on. Thanks!
Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
stageRef.setMaxWidth(primaryScreenBounds.getWidth());
stageRef.setMaxHeight(primaryScreenBounds.getHeight());
GridPane gridPane = new GridPane();
gridPane.setGridLinesVisible(true);
gridPane.setPadding(new Insets(10));
Scene scene = new Scene(gridPane);
VBox vBoxMain = new VBox();
vBoxMain.setPrefWidth((primaryScreenBounds.getWidth()/5)*4);
vBoxMain.setPrefHeight(primaryScreenBounds.getHeight());
TextArea textArea = new TextArea();
textArea.setWrapText(true);
textArea.setPrefHeight(primaryScreenBounds.getHeight());
vBoxMain.getChildren().addAll(textArea);
vBoxMain.isResizable();
VBox vBoxSide = new VBox();
vBoxSide.setPrefWidth((primaryScreenBounds.getWidth()/5));
vBoxSide.setPrefHeight(primaryScreenBounds.getHeight());
vBoxSide.isResizable();
gridPane.add(vBoxSide, 1,1,1,1);
gridPane.add(vBoxMain, 2,1,4,1);
stageRef.setScene(scene);
stageRef.show();
You could use a SplitPane:
A control that has two or more sides, each separated by a divider,
which can be dragged by the user to give more space to one of the
sides, resulting in the other side shrinking by an equal amount.
Then you add two others containers to this pane allowing the user to change the position of the divider. You can also set minimum widths for each component within the pane or set the position of each divider within your code.
I have a problem with changing the location of my Button i want to set a Specific location where to put it but when i use .setLayoutX and .setLayoutY i even tried using .relocate and it is still not working am i doing something wrong? here is my sample code.
CODE
Button b1 = new Button();
b1.setText("Press");
b1.setLayoutX(100);
b1.setLayoutY(120); // this are just some randome numbers for this sample
StackPane pane = new StackPane();
pane.getChildren().add(b1);
Scene scene = new Scene(pane,500,500);
stage.setScenes(scene);
stage.show();
when i run the program the button is still in the center of the screen am doing something wrong?
Use Anchor pane or a pane to align nodes as per your layout.
StackPane, GridPane and many panes they come with inbuilt layout methods, you dont have control on locating the nodes based on x and y values.
I am trying to learn JavaFX and I've run into a problem with the Menus in my MenuBar. Here is a minimal example:
public void start(Stage mainStage) throws Exception {
BorderPane root = new BorderPane();
Scene scene = new Scene(root, 1200, 1000, Color.WHITE);
MenuBar menuBar = new MenuBar();
Menu menuFile = new Menu("_File");
menuBar.getMenus().add(menuFile);
MenuItem add = new MenuItem("_New");
menuFile.getItems().add(add);
root.getChildren().add(menuBar);
menuBar.prefWidthProperty().bind(mainStage.widthProperty());
mainStage.setScene(scene);
mainStage.show();
}
This application starts, but the Menu in the MenuBar is only shown as three dots (...). It does open however when I press ALT+F, so it is there.
From what I understand, a Menu item has no width or similar attribute, so that can't be set. I suspect it has something to do with my root node being a BorderPane, because in every other example I found that works, the root is either a VBox or something else. I seem to get the desired results when I place a Vbox as my root node, and then add the MenuBar and the BorderPane` to the root - but that seems like a strange and uneccesary workaround to me.
So what am I missing here? Is it true that a MenuBar will only ever look like it should in certain containers? What is the difference between a BorderPane and a VBox in this regard? If someone could explain or point me to a part of the documentation that I've missed, I would be very thankful.
You are using a BorderPane and using getChildren().add() to add MenuBar in it, which is incorrect. BorderPane unlike VBox, can't accept any number of children and is divided into 5 specific positions :
top
left
right
bottom
center
The children goes into any one of these positions. Please go through the documentation for BorderPane.
You need to add the Menubar to the top of the BorderPane using :
root.setTop(menuBar);
