This is the base class of HBox and VBox. It has the code necessary to maintain the contained list of widgets, but it does not position them.
Box uses a notion of packing. Packing refers to adding widgets with reference to a particular position in a Container. For a Box, there are two reference positions: the start and the end of the box. For a VBox, the start is defined as the top of the box and the end is defined as the bottom. For a HBox the start is defined as the left side and the end is defined as the right side.
Use repeated calls to packStart
to pack widgets into a
Box from start to end. Use packEnd
to add widgets from end
to start. You may intersperse these calls and add widgets from both ends
of the same Box.

Method Detail |
public void packStart(Widget child)
child
- The widget to be added to the box.public void packStart(Widget child, boolean expand, boolean fill, int padding)
child
- The widget to be added.expand
- TRUE if the new child is to be given extra space
allocated to box. The extra space will be divided evenly between all
children of box that use this option.fill
- TRUE if space given to child by the expand option is
actually allocated to child, rather than just padding it. This parameter
has no effect if expand is set to FALSE. A child is always allocated the
full height of a HBox and the full width of a VBox. This option affects
the other dimension.padding
- Extra space in pixels to put between this child and its
neighbors, over and above the global amount specified by spacing in Box.
If child is a widget at one of the reference ends of box, then padding
pixels are also put between child and the reference edge of Box.public void packEnd(Widget child)

public void setSpacing(int spacing)
spacing
- The number of pixels to put between children.public int getSpacing()
public void reorderChild(Widget child, int position)
A widget's position in the box children list determines where the widget is packed into box. A child widget at some position in the list will be packed just after all other widgets of the same packing type that appear earlier in the list.
child
- The widget to moveposition
- The new position for child in the box, starting from 0.
If negative, the end of the list is used.public static Type getType()
