Class TrueHexGridLayout

java.lang.Object

net.sf.colossus.gui.TrueHexGridLayout

All Implemented Interfaces:

LayoutManager

public class TrueHexGridLayout
extends Object
implements LayoutManager

The TrueHexGridLayout class is a layout manager that lays out a container's components in a grid with alternate rows offset by a partial grid component. The vertical gap is automatically sized so that the Hex components can draw the non base-rectangle portions of the hexes in the gap. This results in a hexagonal tesselation.

When constructed, the layout can start with an indented row or not. The sizing can be done Isometrically or not. TODO: implement the containers ComponentOrientation property If either the Number of Rows or the Number of Columns is set to Zero either by constructor or the set rows or set columns method, then the grid will be assumed to be square and layed out as such. This class is used for battle Hexes.

Method Details

addLayoutComponent

public void addLayoutComponent(String name,
 Component comp)

Specified by:

addLayoutComponent in interface LayoutManager

removeLayoutComponent

public void removeLayoutComponent(Component comp)

Specified by:

removeLayoutComponent in interface LayoutManager

layoutContainer

public void layoutContainer(Container parent)

Lays out the specified container using this layout.

This method resizes the components in the specified target container in order to satisfy the constraints of the BattleHexGridLayout object.

This layout manager determines the size of individual components by dividing the free space in the container into equal-sized portions according to the number of rows and columns in the layout. The container's free space equals the container's size minus any insets and vertical gap needed. All components in the layout are given the same size.

parent - the container in which to do the layout
