Enables a component to stick to a specific side of form and/or to
grow or shrink when a window is resized.

If opposite anchors are activated then the component with grow or
shrink with the window. For example if Top and Bottom are activated,
then the component will grow/shrink when the window is vertically
resized. If Left and Right are activated then the component
will grow/shrink when the window is horizontally resized.

If opposite anchors are not activated, then the component will
keep a constant distance from the sides of the window which
correspond to the activated anchors.

The background color of the component.

The type, color and style of border of the component.

Flag that tells if the component should be printed or not when the form is printed.

Flag that tells how to arrange the tabs if they don't fit on a single line.
If this flag is set, then the tabs will stay on a single line, but there will
be the possibility to scroll them to the left and to the right. If this flag
is not set, then the tabs will be arranged on multiple lines.

The width and height (in pixels), separated by a comma.

The name of the style class that should be applied to this component.

When defining style classes for specific component types, their names
must be prefixed according to the type of the component. For example
in order to define a class names 'fancy' for fields, in the style
definition the class must be named 'field.fancy'. If it would be
intended for labels, then it would be named 'label.fancy'. When specifying
the class name for a component, the prefix is dropped however. Thus the
field or the label will have its styleClass property set to 'fancy' only.

the tab panel into an accordion.
