Enum PositionScheme
- All Implemented Interfaces:
java.io.Serializable
,java.lang.Comparable<PositionScheme>
,java.lang.constant.Constable
public enum PositionScheme extends java.lang.Enum<PositionScheme>
The layout mechanism determines how the widget positions itself relative to the parent or sibling widgets.

Enum Constant Details
-
Static
Static position scheme.The widget is layed-out with other
Static
andRelative
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
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
Absolute position scheme.The widget is positioned at an absolute position with respect to the nearest ancestor widget that is either:
- a
WTableCell
- or has a position scheme that is
Relative
orAbsolute
.
- a
-
Fixed
Fixed position scheme.The widget is positioned at fixed position with respect to the browser's view-pane.
