Returns the maximum amount of space the layout can use.

Specified by:

maximumLayoutSize in interface LayoutManager2

Returns:

a Dimension object containing the layout's maximum size

layoutContainer

public void layoutContainer(Container parent)

Instructs the layout manager to perform the layout for the specified container.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

parent - the container to be laid out

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

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

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.

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
