Constructor Detail

ALayout

public ALayout()

Default Constructor with spacing of 2 and columns filled

ALayout

public ALayout(int spaceH,
               int spaceV,
               boolean colFill)

Detail Contructor

Parameters:

spaceH - horizontal space (top, between rows, button)

spaceV - vertical space (left, between columns, right)

colFill - fields are fully filled (rather then preferred size)

Method Detail

addLayoutComponent

public void addLayoutComponent(String name,
                               Component comp)

Add To Layout with NULL constraint

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

name - the string to be associated with the component - ignored

comp - the component to be added

addLayoutComponent

public void addLayoutComponent(Component component,
                               Object constraint)

Adds the specified component to the layout, using the specified constraint object. If the constraint is not a ALayoutConstraint the component is added with a NULL constraint.

Components with a NULL constraint are added as the next column to the last row

Specified by:

addLayoutComponent in interface LayoutManager2

Parameters:

component - the component to be added

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

ALayoutConstraint

removeLayoutComponent

public void removeLayoutComponent(Component comp)

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 parent)

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

Specified by:

preferredLayoutSize in interface LayoutManager

Parameters:

parent - the container to be laid out

Returns:

Size

See Also:

minimumLayoutSize(java.awt.Container)

minimumLayoutSize

public Dimension minimumLayoutSize(Container parent)

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

Specified by:

minimumLayoutSize in interface LayoutManager

Parameters:

parent - the component to be laid out

Returns:

Size

See Also:

preferredLayoutSize(java.awt.Container)

maximumLayoutSize

public Dimension maximumLayoutSize(Container parent)

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

Specified by:

maximumLayoutSize in interface LayoutManager2

Parameters:

parent - Parent Container

Returns:

Size

See Also:

Component.getMaximumSize(), LayoutManager

layoutContainer

public void layoutContainer(Container parent)

Lays out the specified container.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

parent - the container to be laid out

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 - target

Returns:

0f

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 - target

Returns:

0f

invalidateLayout

public void invalidateLayout(Container target)

Specified by:

invalidateLayout in interface LayoutManager2

Parameters:

target - target

getRowCount

public int getRowCount()

Get Number of Rows

Returns:

no pf rows

getColCount

public int getColCount()

Get Number of Columns

Returns:
