The width is the largest prefered width and the height is the largest prefered height of all these child components.
- Field Value:
- 20
public static final int NONE
Do not resize the child components.
- Field Value:
- 0

Put the component at the top-right corner of its display area.
- Field Value:
- 12
public static final int NORTHWEST
Put each component in the top-left corner of its display area.
- Field Value:
- 18
public static final int ROWCOLPREFERRED
Size all cells so that all in the same row are the same height and all in the same column are the same width. A possible value for the cellSizing parameter of the constructor. The width is the largest prefered width of all components in the same column and the height is the largest prefered height of all components in the same row.
- Field Value:
- 21
public static final int SOUTH
Put the component at the bottom of its display area, centered horizontally.
- Field Value:

public static final int SOUTHEAST
Put the component at the bottom-right corner of its display area.
- Field Value:
- 14
public static final int SOUTHWEST
Put the component at the bottom-left corner of its display area.
- Field Value:
- 16
public static final int VERTICAL
Resize all child components to fit their cell vertically but not horizontally.
- Field Value:
- 3
public static final int WEST
Put the component on the left side of its display area, centered vertically.
- Field Value:
- 17

public void addLayoutComponent(String name, Component comp)
Adds the specified component with the specified name to the layout. This is included to satisfy the LayoutManager interface but is not actually used in this layout implementation.
- Parameters:
name
- the name of the componentcomp
- the component to be added
protected Dimension calculateSizes(Container parent, theColWidth[] , theRowHeight[] , int actualRows, int actualCols, int theLargestWidth, int theLargestHeight)
Calculate the layout size.
- Parameters:
parent
- the containeractualRows
- the number of rows specified for the grid. This should be a non negative integer, where '0' means 'any number' meaning that the number of rows in that dimension depends on the other dimension.actualCols
- the number of columns specified for the grid. This should be a non negative integer, where '0' means 'any number' meaning that the number of columns in that dimension depends on the other dimension.theLargestWidth
- the largest widththeLargestHeight
- the largest height
- Returns:
- the dimension of the layout

- Returns:
- Returns the colWidth.
public int getColumns()

public Dimension preferredLayoutSize(Container parent)
Determines the preferred size of the container argument using this grid layout. The preferred size of a grid layout is dependant on the cellSizing scheme. MAXPREFERRED and FITPARENT use the same formula to calculate prefered size. The prefered width using MAXPREFERRED or FITPARENT is the largest preferred width of any of the widths in the container times the number of columns, plus the horizontal padding times the number of columns plus one, plus the left and right insets of the target container. The preferred height using MAXPREFERRED or FITPARENT is the largest preferred height of any of the heights in the container times the number of rows, plus the vertical padding times the number of rows plus one, plus the top and bottom insets of the target container. The prefered width using ROWCOLPREFERRED is the largest preferred is the sum of the widths of of all columns, plus the horizontal padding times the number of columns plus one, plus the left and right insets of the target container. The prefered height using ROWCOLPREFERRED is the largest preferred is the sum of the heights of of all columns, plus the horizontal padding times the number of columns plus one, plus the left and right insets of the target container.

parent
- the container to be laid out
- Returns:
- the preferred dimensions to lay out the subcomponents of the specified container
