center (subscene) of borderpane not resizing

I'm making an application that uses a SubScene instance on the BorderPane center, and on the right side i want to put a vbox with some content. The subscene starts with the correct size, and resizes perfectly when maximizing the window. before maximizing, maximized
The problem is, when minimizing the window this happens:
minimized
What can I do?
Here's how I managed the resizing system:
SubScene subScene = new SubScene(group, 1200, 700, true, SceneAntialiasing.BALANCED);
HBox centerBox = new HBox();
subScene.widthProperty().bind(centerBox.widthProperty());
subScene.heightProperty().bind(centerBox.heightProperty());
centerBox.getChildren().add(subScene);

For anyone with the same problem. I solved it by binding the SubScene width and height properties with the scene's, and then subtracting the width(200) and height(75) of adjacent nodes:
// Scene scene = new Scene(root, 1200, 800, true);
// SubScene subScene = new SubScene(group, 1200, 700, true, SceneAntialiasing.BALANCED);
// centerBox is an instance of HBox
subScene.widthProperty().bind(scene.widthProperty().subtract(200));
subScene.heightProperty().bind(scene.heightProperty().subtract(75));
centerBox.getChildren().add(subScene);

How do I insert text into a shape in Javafx?

Using JavaFX I have created a simple rectangle object, and I want to be able to put a text object inside that rectangle, and for it to automatically stay aligned within the rectangle. The code I have to draw the rectangle is:
public static Scene createScene() {
Group root = new Group();
Scene scene = new Scene(root, Color.ALICEBLUE);
Rectangle rectangle_red = new Rectangle();
rectangle_red.setFill(Color.TRANSPARENT);
rectangle_red.setStroke(Color.BLACK);
rectangle_red.setX(50);
rectangle_red.setY(50);
rectangle_red.setWidth(200);
rectangle_red.setHeight(100);
rectangle_red.setCursor(Cursor.HAND);
rectangle_red.setOnMousePressed(circleOnMousePressedEventHandler);
rectangle_red.setOnMouseDragged(circleOnMouseDraggedEventHandler);
root.getChildren().add(rectangle_red);
return scene;
}
The Handlers I have attached to the rectangle allow me to drag the rectangles anywhere in the window. How do I place text inside the rectangle such that it stays aligned as I drag the shape around the screen?

As illustrated in the last example seen here, the Animation Basics example TimelineEvents does this by adding a Circle and some Text to a StackPane, which centers its children by default. The stack can then be moved within an enclosing Group as a unit.
final Circle circle = new Circle(…);
final Text text = new Text (…);
final StackPane stack = new StackPane();
stack.getChildren().addAll(circle, text);
…
stack.setLayoutX(30);
stack.setLayoutY(30);

setX and setY not working when trying to position images

I am having problems with positioning my images in my JavaFX program using setX and setY on the ImageView's for the images. I am not sure what is the problem? Appreciate any help given!
Here's my code:
Image rocket2 = new Image("img/Rocket.png");
ImageView iv1 = new ImageView(rocket2);
iv1.setX(60);
iv1.setY(44);
Image rocket1 = new Image("img/Rocket.png");
ImageView iv2 = new ImageView(rocket1);
iv2.setX(5);
iv2.setY(16);
Image background = new Image("img/space.png");
ImageView iv3 = new ImageView(background);
StackPane root = new StackPane();
root.getChildren().addAll(iv3, iv2, iv1);
Scene scene = new Scene(root, 300, 300);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.setResizable(false);
primaryStage.setTitle("Space stuff");
primaryStage.show();
I suspect that something goes wrong because I have set a background image.
img here on what's happening

Don't place your items in a StackPane if you want to explicitly define their layout positions (setX and setY). A StackPane is a managed layout pane. It will automatically set the location of items added to it (default is to center everything one on top of the other inside the StackPane).
Instead use a Pane or a Group, which are not managed layout panes and allow you to layout your content in the Pane however you wish.
To layout your content inside the Pane, you can use setLayoutX and setLayoutY rather than setX and setY, though I guess setX and setY should also work (I've never used them before on ImageView).
Pavlo, already created an answer while I was typing this (so this answer is a duplicate), but I'll leave this as it adds a bit more explanation.

Replacing StackPane with Pane should solve the problem.

If you however want for whatever reason to position a item in a StackPane you can use setTranslateX and setTranslateY. Theese methods set the x and y values AFTER the StackPane has done its layouting, so you will have a different starting position depending on the Alignment your StackPane uses for its children.

ImageView always scaling beyond scene size, can't seem to force it to fit

I am new to JavaFX (been working with swing for a long time) and am trying to work with BorderPane. One would assume BorderPane is similar to BorderLayout but the big difference is the center of BorderPane will expand to fit its contents while BorderLayout will shrink to fit the window.
I am using JFXPanel in a JFrame and have a 3 part interface: A panel on the left (some text), some buttons on the bottom (flow control), and in the center want to have a dynamic panel/pane, that for the most part will be just an imageview. I set it all up and it works fine, but I'm working with camera images here which are way bigger than my monitor. I've tried scaling the images down by binding the imageview width to different things (such as anchor pane, scene size (works, but not properly), etc. The issue I am having is that since borderpane's center panel expands to fit its content, it will expand and never have a proper value I can bind to. I need the image to be fully visible in the window at any size.
Here's the code I've been working with.
protected void setupFXWindow(JFXPanel mainPanel) {
butNext = new Button("Next Step");
butBack = new Button("PreviousStep Step");
butQuit = new Button("Cancel Signature Generation");
butNext.setTooltip(new Tooltip("Next step..."));
butBack.setTooltip(new Tooltip("Previous Step..."));
butQuit.setTooltip(new Tooltip("Quit generating a signature"));
Group root = new Group();
Scene scene = new Scene(root, javafx.scene.paint.Color.ALICEBLUE);
javafx.scene.image.Image fximage = new javafx.scene.image.Image(new File(image.getSourceFilePath()).toURI().toString());
ImageView iv1 = new ImageView();
iv1.setImage(fximage);
iv1.setPreserveRatio(true);
VBox directionsPanel = new VBox();
HBox authorflowPanel = new HBox(); //bottom buttons for next, back, etc.
mainPanel.setScene(scene);
//INSTRUCTIONS
directionsStepLabel = new Text();
directionsLabel = new Text();
setDirectionsText("Directions will be placed here.");
exampleLabel = new Text("Example");
exampleIconLabel = new Text("An example image will be shown here.");
directionsPanel.setPadding(new javafx.geometry.Insets(5, 5, 5, 5));
directionsPanel.getChildren().addAll(directionsStepLabel, directionsLabel, exampleLabel);
authorflowPanel.getChildren().addAll(butBack, butQuit, butNext);
BorderPane bp = new BorderPane();
bp.prefHeightProperty().bind(scene.heightProperty());
bp.prefWidthProperty().bind(scene.widthProperty());
bp.setLeft(directionsPanel);
bp.setBottom(authorflowPanel);
bp.setCenter(iv1);
root.getChildren().add(bp);
}
This code sample doesn't have iv1 (imageview) binded to anything, cause at this point I have no idea what I can bind to that will give me the remaining space in the scene. Since I cannot use the full width or height of the scene, I'm at a loss of what I am supposed to do here.
The code above makes it look like this:

Wrap the ImageView in some kind of Pane (e.g. a StackPane). Then the pane will fill the center region of the border pane and you can bind to its width and height:
ImageView iv1 = new ImageView();
iv1.setImage(fximage);
iv1.setPreserveRatio(true);
StackPane imageContainer = new StackPane(iv1);
iv1.fitWidthProperty().bind(imageContainer.widthProperty());
iv1.fitHeightProperty().bind(imageContainer.heightProperty());
// ...
bp.setCenter(imageContainer);

Disable automatic resizing, without disabling manual resizing

Coding a GUI in a Java project I've encountered a problem with JavaFX.
I've not found any soulutions for my specific problem, so here I am:)
Is it possible to let a JavaFX scene be resizeable by the user and at the same time have it not resized by child nodes, that are bigger, than the window?
Here is some sample code:
#Override
public void startGUI(int width, int height) {
this.main = new MainWindow(this, this.logic);
this.scene = new Scene(this.main.getRoot());
this.main.setScene(this.scene);
this.primaryStage.setScene(this.scene);
this.primaryStage.setMinHeight(height);
this.primaryStage.setMinWidth(width);
}
The 'MainWindow' has got a childnode, that can be very big (>1024x768).
I want the window not to be resized by this node, but at the same time, the user should be able to resize the window by dragging its borders.

Use a Scene constructor which specifies initial size constraints.
For example:
Scene scene = new Scene(root, 600, 400);
That way the initial size of the Scene will be taken from these constraints rather than calculated from the preferred size of the root node.
