Constructor Detail

AbstractLayout

public AbstractLayout()

Creates a new AbstractLayout object.

AbstractLayout

public AbstractLayout(int hgap,
                      int vgap)

Creates a new AbstractLayout object.

Parameters:

hgap - DOCUMENT ME!

vgap - DOCUMENT ME!

Method Detail

getHgap

public int getHgap()

Get the horizontal gap between components.

getVgap

public int getVgap()

Get the vertical gap between components.

setHgap

public void setHgap(int gap)

Set the horizontal gap between components.

Parameters:

gap - The horizontal gap to be set

setVgap

public void setVgap(int gap)

Set the vertical gap between components.

Parameters:

gap - The vertical gap to be set

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)

Returns the maximum dimensions for this layout given the component in the specified target container.

Specified by:

maximumLayoutSize in interface LayoutManager2

Parameters:

target - The component which needs to be laid out

getLayoutAlignmentX

public float getLayoutAlignmentX(Container parent)

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 parent)

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)

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

Specified by:

invalidateLayout in interface LayoutManager2

addLayoutComponent

public void addLayoutComponent(String name,
                               Component comp)

Adds the specified component with the specified name to the layout. By default, we call the more recent addLayoutComponent method with an object constraint argument. The name is passed through directly.

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

name - The name of the component

comp - The component to be added

addLayoutComponent

public void addLayoutComponent(Component comp,
                               Object constraints)

Add the specified component from the layout. By default, we let the Container handle this directly.

Specified by:

addLayoutComponent in interface LayoutManager2

Parameters:

comp - The component to be added

constraints - The constraints to apply when laying out.

removeLayoutComponent

public void removeLayoutComponent(Component comp)

Removes the specified component from the layout. By default, we let the Container handle this directly.

Specified by:

removeLayoutComponent in interface LayoutManager

Parameters:

comp - the component to be removed

toString

public String toString()

Return a string representation of the layout manager

Overrides:

toString in class Object
