Method Detail

calculateMinimumSize

protected 
Dimension calculateMinimumSize(
IFigure container,
                                         int wHint,
                                         int hHint)
Description copied from class: AbstractHintLayout
Calculates the minimum size using the given width and height hints. This method is called from AbstractHintLayout.getMinimumSize(IFigure, int, int) whenever the cached minimum size has been flushed.

By default, this method just calls AbstractHintLayout.getPreferredSize(IFigure, int, int), meaning minimum and preferres sizes will be the same unless this method is overridden.

Overrides:
calculateMinimumSize in class AbstractHintLayout
Parameters:
container - the Figure on which this layout is installed
wHint - the width hint
hHint - the height hint
Returns:
the layout's minimum size
See Also:
AbstractHintLayout.calculateMinimumSize(IFigure, int, int)

calculatePreferredSize

protected 
Dimension calculatePreferredSize(
IFigure container,
                                           int wHint,
                                           int hHint)
Description copied from class: AbstractLayout
Calculates the preferred size of the given figure, using width and height hints.

Specified by:
calculatePreferredSize in class AbstractLayout
Parameters:
container - The figure
wHint - The width hint
hHint - The height hint
Returns:
The preferred size
See Also:
AbstractLayout.calculatePreferredSize(IFigure, int, int)

layout

public void layout(
IFigure container)
Description copied from interface: LayoutManager
Lays out the given figure.

Parameters:
container - The figure
See Also:
LayoutManager.layout(IFigure)

remove

public void remove(
IFigure child)
Description copied from class: AbstractLayout
Removes the given figure from this LayoutManager's list of figures.

Specified by:
remove in interface LayoutManager
Overrides:
remove in class AbstractLayout
Parameters:
child - The figure to remove
See Also:
AbstractLayout.remove(IFigure)

setConstraint

public void setConstraint(
IFigure child,
                          java.lang.Object constraint)
Sets the location of hte given child in this layout. Valid constraints:

Ensure that the given Figure is indeed a child of the Figure on which this layout has been set. Proper behaviour cannot be guaranteed if that is not the case. Also ensure that every child has a valid constraint.

Passing a null constraint will invoke remove(IFigure).

If the given child was assigned another constraint earlier, it will be re-assigned to the new constraint. If there is another child with the given constraint, it will be over-ridden so that the given child now has that constraint.

Specified by:
setConstraint in interface LayoutManager
Overrides:
setConstraint in class AbstractLayout
Parameters:
child - the child
constraint - the child's new constraint
See Also:
AbstractLayout.setConstraint(IFigure, Object)

setHorizontalSpacing

public void setHorizontalSpacing(int gap)
Sets the horizontal spacing to be used between the children. Default is 0.

Parameters:
gap - The horizonal spacing

setVerticalSpacing

public void setVerticalSpacing(int gap)
Sets the vertical spacing ot be used between the children. Default is 0.

Parameters:
gap - The vertical spacing
