Method Summary

void	addLayoutComponent(Component comp, Object constraints) Adds the specified component to the layout, using the specified constraint object.
void	addLayoutComponent(String name, Component comp) If the layout manager uses a per-component string, adds the component comp to the layout, associating it with the string specified by name.
float	getLayoutAlignmentX(Container target) Returns the alignment along the x axis.
float	getLayoutAlignmentY(Container target) Returns the alignment along the y axis.
void	invalidateLayout(Container target) Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.
void	layoutContainer(Container target) Lays out the specified container.
Dimension	maximumLayoutSize(Container target) Calculates the maximum size dimensions for the specified container, given the components it contains.
Dimension	minimumLayoutSize(Container target) Calculates the minimum size dimensions for the specified container, given the components it contains.
Dimension	preferredLayoutSize(Container target) Calculates the preferred size dimensions for the specified container, given the components it contains.

Method Detail

addLayoutComponent

public void addLayoutComponent(String name,
                               Component comp)

Description copied from interface: LayoutManager

If the layout manager uses a per-component string, adds the component comp to the layout, associating it with the string specified by name.

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

name - the string to be associated with the component

comp - the component to be added

addLayoutComponent

public void addLayoutComponent(Component comp,
                               Object constraints)

Description copied from interface: LayoutManager2

Adds the specified component to the layout, using the specified constraint object.

Specified by:

addLayoutComponent in interface LayoutManager2

Parameters:

comp - the component to be added

constraints - where/how the component is added to the layout.

removeLayoutComponent

public void removeLayoutComponent(Component comp)

Description copied from interface: LayoutManager

Removes the specified component from the layout.

Specified by:

removeLayoutComponent in interface LayoutManager

Parameters:

comp - the component to be removed

preferredLayoutSize

public Dimension preferredLayoutSize(Container target)

Description copied from interface: LayoutManager

Calculates the preferred size dimensions for the specified container, given the components it contains.

Specified by:

preferredLayoutSize in interface LayoutManager

Parameters:

target - the container to be laid out

See Also:

LayoutManager.minimumLayoutSize(java.awt.Container)

minimumLayoutSize

public Dimension minimumLayoutSize(Container target)

Description copied from interface: LayoutManager

Calculates the minimum size dimensions for the specified container, given the components it contains.

Specified by:

minimumLayoutSize in interface LayoutManager

Parameters:

target - the component to be laid out

See Also:

LayoutManager.preferredLayoutSize(java.awt.Container)

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)

Description copied from interface: LayoutManager2

Calculates the maximum size dimensions for the specified container, given the components it contains.

Specified by:

maximumLayoutSize in interface LayoutManager2

Component.getMaximumSize(), LayoutManager

layoutContainer

public void layoutContainer(Container target)

Description copied from interface: LayoutManager

Lays out the specified container.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

target - the container to be laid out

getLayoutAlignmentX

public float getLayoutAlignmentX(Container target)

Description copied from interface: LayoutManager2

Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentX in interface LayoutManager2

getLayoutAlignmentY

public float getLayoutAlignmentY(Container target)

Description copied from interface: LayoutManager2

Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentY in interface LayoutManager2

invalidateLayout

public void invalidateLayout(Container target)

Description copied from interface: LayoutManager2

Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.

Specified by:

invalidateLayout in interface LayoutManager2

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent e)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener
