public enum PositionScheme
extends java.lang.Enum<PositionScheme>
Enumeration that specifies a layout mechanism for a widget.

The layout mechanism determines how the widget positions itself relative to the parent or sibling widgets.

    • Static

      public static final PositionScheme Static
      Static position scheme.

      The widget is layed-out with other Static and Relative sibling widgets, one after another.

      Inline widgets are layed out in horizontal lines (like text), wrapping around at the end of the line to continue on the next line. Block widgets are stacked vertically.

      Static widgets may also float to the left or right border, using setFloatSide().

    • Relative

      public static final PositionScheme Relative
      Relative position scheme.

      The widget is first layed out according to Static layout rules, but after layout, the widget may be offset relative to where it would be in a static layout, using setOffsets().

      Another common use of a Relative position scheme (even with no specified offsets) is to provide a new reference coordinate system for Absolutely positioned widgets.

    • Absolute

      public static final PositionScheme Absolute
      Absolute position scheme.

      The widget is positioned at an absolute position with respect to the nearest ancestor widget that is either:

    • Fixed

      public static final PositionScheme Fixed
      Fixed position scheme.

      The widget is positioned at fixed position with respect to the browser's view-pane.

  • Method Details

    • values

      public static PositionScheme[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static PositionScheme valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
      java.lang.NullPointerException - if the argument is null
    • getValue

      public int getValue()
      Returns the numerical representation of this enum.
