Class LayoutRow

java.lang.Object
oracle.javatools.columnlayout.LayoutRow

All Implemented Interfaces:

LayoutComponent

public class LayoutRow

extends java.lang.Object

implements LayoutComponent

A LayoutRow is a list of LayoutComponents. Each row in a LayoutPanel is a LayoutRow.

Constructor Summary

LayoutRow()

Method Summary

void	add(LayoutComponent lc) Add a LayoutComponent to the row.
void	addToPanel(java.awt.Container container, int baseRow, int baseColumn, boolean[] rowConstraints, boolean[] columnConstraints, int rowSpan) Allow each LayoutComponent to add itself to the UI container with appropriate constraints.
void	areColumnsResizable(boolean[] columnConstraints, int baseColumn) Allow each LayoutComponent to set the column constraints.
void	areRowsResizable(boolean[] rowConstraints, int baseRow, int rowSpan) Allow each LayoutComponent to set the row constraints.
int	getColumnCount() Returns the sum of the added LayoutComponents column counts.
int	getRowCount() Returns the maximum row count of the added LayoutComponents.

Method Detail

addToPanel

public void addToPanel(java.awt.Container container,
                       int baseRow,
                       int baseColumn,
                       boolean[] rowConstraints,
                       boolean[] columnConstraints,
                       int rowSpan)

Allow each LayoutComponent to add itself to the UI container with appropriate constraints. The row span may be larger than the number of rows, but the individual LayoutComponents must deal with that difference.

Specified by:

addToPanel in interface LayoutComponent

Parameters:

container - the container to add to

baseRow - components must be added relative to this

baseColumn - components must be added relative to this

rowConstraints - whether each row is resizable or not, these are for the whole container

columnConstraints - same as rowConstraints but for columns

rowSpan - the number of rows which the LayoutComponent occupies this will be at least equal to the LayoutComponent's row count

areRowsResizable

public void areRowsResizable(boolean[] rowConstraints,
                             int baseRow,
                             int rowSpan)

Allow each LayoutComponent to set the row constraints. The row span may be larger than the number of rows, but the individual LayoutComponents must deal with that difference.

Specified by:

areRowsResizable in interface LayoutComponent

Parameters:

rowConstraints - the out parameter

baseRow - the position to start from in the rowConstraints

rowSpan - the length of the rowConstraints which can be changed

areColumnsResizable

public void areColumnsResizable(boolean[] columnConstraints,
                                int baseColumn)

Allow each LayoutComponent to set the column constraints.

Specified by:

areColumnsResizable in interface LayoutComponent

getRowCount

public int getRowCount()

Returns the maximum row count of the added LayoutComponents.

Specified by:

getRowCount in interface LayoutComponent

getColumnCount

public int getColumnCount()

Returns the sum of the added LayoutComponents column counts.

Specified by:

getColumnCount in interface LayoutComponent

add

public void add(LayoutComponent lc)

Add a LayoutComponent to the row. Recalculating all the row and column counts. After the LayoutComponent had been added it must not change size.

Parameters:

lc - the layout component to add, must not be null
