Class LayoutGap

java.lang.Object

oracle.javatools.columnlayout.LayoutGap

All Implemented Interfaces:

LayoutComponent

public class LayoutGap
extends java.lang.Object
implements LayoutComponent

Gaps are represented as JPanels with their preferred size set to the required gap size. They always occupy a single row and column and don't do any resizability checks.

Constructor Detail

LayoutGap

public LayoutGap(java.awt.Dimension dimension)

Create a LayoutGap with the supplied minimum dimensions.

Parameters:

dimension - minimum size of gap, must not be null

LayoutGap

public LayoutGap(int width,
                 int height)

Create a LayoutGap using by supplying the width and height, this creates a new dimension.

Method Detail

areRowsResizable

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

Gaps have no effect on row constraints.

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)

Gaps have no effect on column constraints.

Specified by:

areColumnsResizable in interface LayoutComponent

getColumnCount

public int getColumnCount()

Gaps always occupy a single column.

Specified by:

getColumnCount in interface LayoutComponent

getRowCount

public int getRowCount()

Gaps always occupy a single row.

Specified by:

getRowCount in interface LayoutComponent

addToPanel

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

The gap is added at the specified position, as a non-resizable single celled panel.

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
