HBox presentation style attributes apply to an HBox element.
This topic lists presentation style attributes for a specific class of form element, common presentation style attributes can also be used for this type of element.
packed
Allows to pack the elements of a VBOX or HBOX, when there is no
stretchable child element such as a TABLE.
Values can be "yes", "no" (default).
When set to "yes", for a vertical box, elements are packed to the top. For an
horizontal box, elements are packed to the left.
By default, or when this attribute is set to "no", space is inserted between any
two elements, if none of the elements can stretch in the alignment direction of the box.
If the HBOX or VBOX is defined with a SPLITTER
attribute, the packed style attribute is ignored once the user set manually the
splitter positions.
