# Class HBox

java.lang.Object
javafx.scene.Node
javafx.scene.Parent
javafx.scene.layout.Region
javafx.scene.layout.Pane
javafx.scene.layout.HBox

All Implemented Interfaces:
  `Styleable, EventTarget`

public class HBox extends Pane
HBox lays out its children in a single horizontal row. If the hbox has a border and/or padding set, then the contents will be laid out within those insets.

HBox example:

        HBox hbox = new HBox(8); // spacing = 8
        hbox.getChildren().addAll(new Label("Name:"), new TextBox());

HBox will resize children (if resizable) to their preferred widths and uses its fillHeight property to determine whether to resize their heights to fill its own height or keep their heights to their preferred (fillHeight defaults to true). The alignment of the content is controlled by the alignment property, which defaults to Pos.TOP_LEFT.

If an hbox is resized larger than its preferred width, by default it will keep children to their preferred widths, leaving the extra space unused. If an application wishes to have one or more children be allocated that extra space it may optionally set an hgrow constraint on the child. See "Optional Layout Constraints" for details.

HBox lays out each managed child regardless of the child's visible property value; unmanaged children are ignored.

## Resizable Range

An hbox's parent will resize the hbox within the hbox's resizable range during layout. By default the hbox computes this range based on its content as outlined in the table below.

HBox Resize Table
| width | height
minimum | left/right insets plus the sum of each child's min width plus spacing between each child. | top/bottom insets plus the largest of the children's min heights.
preferred | left/right insets plus the sum of each child's pref width plus spacing between each child. | top/bottom insets plus the largest of the children's pref heights.
maximum | Double.MAX_VALUE | Double.MAX_VALUE

An hbox's unbounded maximum width and height are an indication to the parent that it may be resized beyond its preferred size to fill whatever space is assigned to it.

HBox provides properties for setting the size range directly. These properties default to the sentinel value USE_COMPUTED_SIZE, however the application may set them to other values as needed:

        hbox.setPrefWidth(400);

Applications may restore the computed values by setting these properties back to USE_COMPUTED_SIZE.

HBox does not clip its content by default, so it is possible that children's bounds may extend outside its own bounds if a child's min size prevents it from being fit within the hbox.

## Optional Layout Constraints

An application may set constraints on individual children to customize HBox's layout. For each constraint, HBox provides a static method for setting it on the child.

HBox Constraint Table
Constraint | Type | Description
--- | --- | ---
hgrow | javafx.scene.layout.Priority | The horizontal grow priority for the child.
margin | javafx.geometry.Insets | Margin space around the outside of the child.

For example, if an hbox needs the TextField to be allocated all extra space:

        HBox hbox = new HBox();
        TextField field = new TextField();
        HBox.setHgrow(field, Priority.ALWAYS);
        hbox.getChildren().addAll(new Label("Search:"), field, new Button("Go"));

If more than one child has the same grow priority set, then the hbox will allocate equal amounts of space to each. HBox will only grow a child up to its maximum width, so if the child has a max width other than Double.MAX_VALUE, the application may need to override the max to allow it to grow. For example:

        HBox hbox = new HBox();
        Button button1 = new Button("Add");
        Button button2 = new Button("Remove");
        HBox.setHgrow(button1, Priority.ALWAYS);
        HBox.setHgrow(button2, Priority.ALWAYS);
        button1.setMaxWidth(Double.MAX_VALUE);
        button2.setMaxWidth(Double.MAX_VALUE);
        hbox.getChildren().addAll(button1, button2);

- ## Method Details

  - ### setHgrow

    public static void setHgrow(Node child, Priority value)
    Sets the horizontal grow priority for the child when contained by an hbox. If set, the hbox will use the priority value to allocate additional space if the hbox is resized larger than its preferred width. If multiple hbox children have the same horizontal grow priority, then the extra space will be split evenly between them. If no horizontal grow priority is set on a child, the hbox will never allocate any additional horizontal space for that child.

    Setting the value to `null` will remove the constraint.

    Parameters:
      `child` - the child of an hbox
      `value` - the horizontal grow priority for the child

  - ### getHgrow

      the horizontal grow priority for the child or null if no priority was set

  - ### setMargin

    public static void setMargin(Node child, Insets value)
    Sets the margin for the child when contained by an hbox. If set, the hbox will layout the child with the margin space around it. Setting the value to null will remove the constraint.
    Parameters:
      `child` - the child mode of the hbox
      `value` - the margin of space around the child

  - ### getMargin
