Class TrueHexGridLayout

  • All Implemented Interfaces:
    java.awt.LayoutManager

    public class TrueHexGridLayout
    extends java.lang.Object
    implements java.awt.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.

      • layoutContainer

        public void layoutContainer​(java.awt.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.

        Specified by:
        layoutContainer in interface java.awt.LayoutManager
        Parameters:
        parent - the container in which to do the layout
