Method Detail

addLayoutComponent

public void addLayoutComponent(java.lang.String name,
                               java.awt.Component component)

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

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

Parameters:

name - the component name

component - the component to be added

layoutContainer

public void layoutContainer(java.awt.Container container)

ays out the container in the specified panel.

Specified by:

layoutContainer in interface java.awt.LayoutManager

Parameters:

container - the component which needs to be laid out.

minimumLayoutSize

public java.awt.Dimension minimumLayoutSize(java.awt.Container container)

Calculates the minimum size dimensions for the specified panel given the components in the specified parent container.

Specified by:

minimumLayoutSize in interface java.awt.LayoutManager

Parameters:

container - the component to be laid out

Returns:

the minimum layout size of the container.

preferredLayoutSize

public java.awt.Dimension preferredLayoutSize(java.awt.Container container)

Calculates the preferred size dimensions for the specified panel given the components in the specified parent container.

Specified by:

preferredLayoutSize in interface java.awt.LayoutManager

Parameters:

container - the component to be laid out

Returns:

the preferred layout size of the container.

maximumLayoutSize

public java.awt.Dimension maximumLayoutSize(java.awt.Container container)

Returns the maximum size of this component.

Specified by:

maximumLayoutSize in interface java.awt.LayoutManager2

Parameters:

container - the container which needs to be laid out.

Returns:

the maximum size of this component.

removeLayoutComponent

public void removeLayoutComponent(java.awt.Component component)

Removes the specified component from the layout.

Specified by:

removeLayoutComponent in interface java.awt.LayoutManager

Parameters:

component - the component to be removed.

addLayoutComponent

public void addLayoutComponent(java.awt.Component component,
                               java.lang.Object constraints)

Adds the specified component to the layout, using the specified constraint object. The constraint object becomes being put into the hashtable with the component as its key.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager2

Parameters:

component - the component to be added

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

getLayoutAlignmentX

public float getLayoutAlignmentX(java.awt.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 java.awt.LayoutManager2

Parameters:

target - the container whos layout alignment has to be retrieved.

Returns:

a value from 0 to 1.

getLayoutAlignmentY

public float getLayoutAlignmentY(java.awt.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 java.awt.LayoutManager2

Parameters:

target - the container whos layout alignment has to be retrieved.

Returns:

a value from 0 to 1.

invalidateLayout

public void invalidateLayout(java.awt.Container target)

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

Specified by:

invalidateLayout in interface java.awt.LayoutManager2

Parameters:

target - the container of the components of which the information should be invalidated.

getCellBounds

protected java.awt.geom.Rectangle2D.Float getCellBounds(java.awt.Container container)

container - the container to get the cell bounds of.

Returns:

the bounds of the cells.

getMinimumCellSize

public java.awt.Dimension getMinimumCellSize(java.awt.Container container)

Gets the mimumum size of a cell for the given container.

Parameters:

container - The container to get the minimum cell size for.

Returns:

the minimum size of a single cell in pixels.
