JavaFX is a software platform for creating and delivering desktop applications, and it comes with a set of built-in layout panes that make it easy to manage the user interface of an application. These layout panes, such as BorderPane, GridPane, FlowPane, TilePane, HBox, VBox, and StackPane, can be used to create classic layouts with rows, columns, stacks, and tiles. JavaFX also provides the ability to manually lay out the UI by setting the position and size properties for each UI element. While it is possible to have multiple panes in one scene, the scene itself can only have one root pane. This means that if you want to have two panes in a scene, you need to have three components: the scene, a root pane, and the two panes. JavaFX also offers the SplitPane class, which contains two or more sides separated by a divider that the user can drag to adjust the space allocated to each side.

What You'll Learn
JavaFX layout panes
The BorderPane layout pane, for example, provides five regions (top, bottom, left, right, and center) to place nodes. Developers can choose to omit regions, and the border pane is useful for creating a toolbar at the top, a status bar at the bottom, a navigation panel on the left, additional information on the right, and a working area in the center. The HBox layout pane, on the other hand, arranges nodes in a single horizontal row, making it ideal for toolbars with multiple buttons.
While JavaFX offers built-in layout panes, developers can also create more complex layouts by nesting different containers within a JavaFX application. This approach is particularly useful for custom controls and more intricate graphical user interfaces (GUIs). However, it is important to note that built-in layout managers, except for GridPane, are basic and may not suit more complex applications. For more complicated layouts, developers can use GridPane or third-party layout managers like MigPane, which offers powerful layout capabilities through string constraints and multiple layout modes.
When using JavaFX layout panes, developers can manually set the position and size properties for each UI element. However, layout panes simplify this process by automatically repositioning and resizing nodes within the pane as the window is resized. This dynamic behaviour ensures that the user interface remains organized and responsive to changes in window dimensions.

SceneBuilder
JavaFX Scene Builder is a tool that allows users to create user interfaces (UI) for JavaFX applications. It provides a graphical interface for arranging UI components and defining their properties. Scene Builder generates FXML files, which describe the UI layout and can be used to create the user interface programmatically.
When creating a UI with Scene Builder, users can utilise various layout panes to arrange UI elements. These include commonly used panes such as HBox, VBox, Border Pane, Stack Pane, Anchor Pane, Grid Pane, and Flow Panel. Layout panes help organise UI components in a structured and visually appealing manner.
One common question regarding JavaFX and Scene Builder is whether multiple panes can exist within a single scene. The answer is yes, but with a specific structure. While a scene can have only one root pane, that root pane can contain multiple panes within it. This allows for complex UI designs where different sections of the interface are organised into separate panes, creating a nested structure.
Scene Builder is particularly useful for rapidly prototyping and designing UIs. It provides a visual representation of the interface, making it easier to understand the layout and arrangement of UI elements. However, for more complex behaviours, such as dynamically populating panes with different content, additional coding may be required. This can involve hand-coding in Java or FXML to achieve the desired functionality.
Overall, JavaFX Scene Builder is a valuable tool for creating user interfaces in JavaFX applications. It simplifies the process of designing UIs by providing a graphical interface and generating FXML layout files. With the ability to nest panes within a scene, developers can build complex and dynamic interfaces while still benefiting from the structure and organisation that layout panes offer.

BorderPane
The BorderPane class is a part of JavaFX, which lays out its children in top, bottom, centre, left and right positions. It is a layout container class, or pane, that is available with the JavaFX SDK. It provides an easy way to manage the user interface for your JavaFX application.
The BorderPane layout provides five regions in which to place nodes: top, bottom, left, right, and centre. The regions can be any size, and if your application does not need one of the regions, you do not need to define it and no space is allocated for it. A border pane is useful for the classic look of a toolbar at the top, a status bar at the bottom, a navigation panel on the left, additional information on the right, and a working area in the centre.
The top and bottom children will be resized to their preferred heights and extend the width of the border pane. The left and right children will be resized to their preferred widths and extend the length between the top and bottom nodes. The centre node will be resized to fill the available space in the middle. Any of the positions may be null.

GridPane
JavaFX provides several layout panes for the easy setup and management of classic layouts such as rows, columns, stacks, and tiles. One of these layout panes is the GridPane, which lays out its children within a flexible grid of rows and columns. The GridPane class of the package javafx.scene.layout provides eleven properties, including alignment, hgap (horizontal gap between columns), vgap (vertical gap between rows), and gridLinesVisible (a boolean property that determines whether the lines of the pane are visible).
A child's placement within the grid is defined by its layout constraints. If the row and column indices are not explicitly set, the child will be placed in the first row and column. Children may be placed anywhere within the grid and may span multiple rows and columns. They may also freely overlap within rows and columns, with their stacking order defined by the order of the GridPane's children list (where the 0th node is at the back, and the last node is at the front).
The total number of rows and columns does not need to be specified upfront as the GridPane will automatically expand or contract the grid to accommodate its children. An application may freely mix the size types of rows and columns (computed from content, fixed, or percentage). The percentage rows and columns will always be allocated space first, followed by the remaining space being allocated to rows and columns based on their minimum, preferred, and maximum sizes and grow priorities.
The GridPane may be styled with backgrounds and borders using CSS. It does not clip its content by default, so it is possible for a child's bounds to extend outside of the GridPane's bounds if the child's minimum size prevents it from fitting within its allocated space. Additional constraints can be set on children to customize their sizing and positioning within the layout area.

StackPane
JavaFX is a set of graphics and media packages that enables the creation of Graphical User Interfaces (GUI) for Java applications. It provides a set of layout panes that can be used to easily manage the user interface of an application. These layout panes include BorderPane, GridPane, FlowPane, TilePane, HBox, VBox, and StackPane.
The StackPane class is a part of JavaFX and is used to lay out its children in the form of a stack. The new node is placed on top of the previous node in a StackPane. StackPane inherits the Pane class and has constructors that can create a new empty StackPane or a new StackPane with specified nodes.
Overall, StackPane is a powerful tool in JavaFX for creating and managing the layout of GUI components in a stacked manner. It provides flexibility in terms of sizing and positioning of child nodes, making it easier to build complex and dynamic user interfaces.

Frequently asked questions
Yes, panes can be nested in JavaFX. This is a common occurrence with custom controls and more complex GUIs.
The scene itself can only have one root pane, so if you want 2 panes in the scene, you need 3. You can use the following code:
```
StackPane rootPane = new StackPane();
Scene scene = new Scene(rootPane...);
Pane pane1 = new Pane();
Pane pane2 = new Pane();
rootPane.getChildren().addAll(pane1, pane2);
```
JavaFX provides several layout panes for the easy setup and management of classic layouts. Some of the layout panes include BorderPane, GridPane, FlowPane, TilePane, HBox, VBox, and StackPane.
Layout panes in JavaFX are used to easily manage the user interface of a JavaFX application. They automatically reposition and resize the nodes within them as the window is resized, based on the properties set for the nodes.
