minimumLayoutSize(java.awt.Container)

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)

Returns the maximum size of this component.

Specified by:

maximumLayoutSize in interface LayoutManager2

Parameters:

target - The component to be laid out.

Returns:

The maximum size for the container.

preferredLayoutSize(java.awt.Container)

addLayoutComponent

public void addLayoutComponent(String name,
                               Component comp)

Adds the specified component with the specified name to the layout.

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

name - the component name

comp - the component to be added

removeLayoutComponent

public void removeLayoutComponent(Component comp)

Removes the specified component from the layout.

Specified by:

removeLayoutComponent in interface LayoutManager

Parameters:

comp - the component ot be removed

layoutContainer

public void layoutContainer(Container target)

Lays out the container.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

target - The container which needs to be laid out.

addLayoutComponent

public void addLayoutComponent(Component comp,
                               Object constraints)

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)

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

Parameters:

target - The target container.

Returns:

The X-axis alignment.

getLayoutAlignmentY

public float getLayoutAlignmentY(Container target)

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

Parameters:

target - The target container.

Returns:

The Y-axis alignment.

invalidateLayout

public void invalidateLayout(Container target)

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

Specified by:

invalidateLayout in interface LayoutManager2

Parameters:

target - The target container.
