AbstractLayout

public interface LayoutManager

Lays out figures, using a constraint if necessary.

Method Summary

Object	getConstraint(IFigure figure) Returns the constraint for the given figure.
Dimension	getMinimumSize(IFigure parent) Returns the minimum size of the given figure.
Dimension	getPreferredSize(IFigure parent) Returns the preferred size of the given figure.
Dimension	getPreferredSize(IFigure parent, int wHint, int hHint) Returns the preferred size of the given figure, using width and height hints.
void	invalidate() Tells the LayoutManager to throw away all cached information about the figures it is resposible for.
void	invalidate(IFigure child) Tells the LayoutManager to throw away any cached information about the given figure.
void	layout(IFigure parent) Lays out the given figure.
void	remove(IFigure figure) Removes the given figure from this LayoutManager.
void	setConstraint(IFigure figure, Object constraint) Sets the constraint for the given figure.
