Method Detail

getConstraint

public Object getConstraint(IFigure child)
Returns the constraint for the given figure.

Parameters:
child - The figure
Returns:
The constraint

getMinimumSize

public Dimension getMinimumSize(IFigure container,
                                int wHint,
                                int hHint)
Returns the minimum size of the given figure.

Parameters:
container - The Figure
wHint - the width hint
hHint - the height hint
Returns:
The minimum size

getPreferredSize

public Dimension getPreferredSize(IFigure container,
                                  int wHint,
                                  int hHint)
Returns the preferred size of the given figure, using width and height hints.

Parameters:
container - The figure
wHint - The width hint
hHint - The height hint
Returns:
The preferred size

invalidate

public void invalidate()
Tells the LayoutManager to throw away all cached information about the figures it is resposible for. This method is called whenever the owning figure is invalidated.


layout

Lays out the given figure.

Parameters:
container - The figure

remove

public void remove(IFigure child)
Removes the given child from this layout.

Parameters:
child - the child being remoced

setConstraint

public void setConstraint(IFigure child,
                          Object constraint)
Sets the constraint for the given child.

Parameters:
child - The figure
constraint - The constraint
