                      double size)

getColumn

public double getColumn(int column)

getNumColumns

public int getNumColumns()

layoutContainer

public void layoutContainer(Container container)

To lay out the specified container using this layout. This method reshapes the components in the specified target container in order to satisfy the constraints of all components.

User code should not have to call this method directly.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

container - container being served by this layout manager

preferredLayoutSize

public Dimension preferredLayoutSize(Container container)

Determines the preferred size of the container argument using this layout. The preferred size is the smallest size that, if used for the container's size, will ensure that all components are at least as large as their preferred size.

Specified by:

preferredLayoutSize in interface LayoutManager

Parameters:

container - container being served by this layout manager

Returns:

a dimension indicating the container's preferred size

minimumLayoutSize

public Dimension minimumLayoutSize(Container container)

Determines the minimum size of the container argument using this layout. The minimum size is the smallest size that, if used for the container's size, will ensure that all components are at least as large as their minimum size.

Specified by:

minimumLayoutSize in interface LayoutManager

Parameters:

container - container being served by this layout manager

Returns:

a dimension indicating the container's minimum size

addLayoutComponent

public void addLayoutComponent(String name,
                               Component component)

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

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

name - indicates entry's position and anchor

component - component to add

addLayoutComponent

public void addLayoutComponent(Component component,
                               Object constraint)

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

Specified by:

addLayoutComponent in interface LayoutManager2

Parameters:

component - component to add

constraint - indicates entry's position and alignment

removeLayoutComponent

public void removeLayoutComponent(Component component)

Removes the specified component from the layout.

Specified by:

removeLayoutComponent in interface LayoutManager

Parameters:

component - component being removed

maximumLayoutSize

public Dimension maximumLayoutSize(Container component)

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

Specified by:

maximumLayoutSize in interface LayoutManager2

Parameters:

component - the component which needs to be laid out

getLayoutAlignmentX

public float getLayoutAlignmentX(Container parent)

Returns the alignment along the x axis.

Specified by:

getLayoutAlignmentX in interface LayoutManager2

Returns:

unconditionally, 0.5

getLayoutAlignmentY

public float getLayoutAlignmentY(Container parent)

Returns the alignment along the y axis.

Specified by:

getLayoutAlignmentY in interface LayoutManager2

Returns:

unconditionally, 0.5

invalidateLayout

public void invalidateLayout(Container target)

Invalidates the layout.

Specified by:

invalidateLayout in interface LayoutManager2

setMargin

public void setMargin(int margin)

Set margin. The margin is the absolute space around the widget.
When you have a 10x10 pixels icon placed on a widget that has a margin of 6 pixels, the complete height of the widget will be 16 pixels, and the icon will be placed in the center.

setSpacing

public void setSpacing(int spacing)

Set spacing. The spacing is the absolute space between each child-widget, when spacing is 6 and an icon is placed at x=10, and has with of 10 then next widget will be placed at 10+10+6 is 26.
Notice that spacing is only between child-widgets; see margin for the area around the parent widget.

getSpacing

public int getSpacing()

getMargin

public int getMargin()
