Implement a simplistic drawing of a grid.

classdef TableGridDraw < handle

    %TABLEGRIDDRAW Draw a TableGrid into a uipanel

    %   Draws a 2D Grid inside a uipanel (Yay!)

    properties

        my_table_grid = []

        controls = []

    end

    methods

        function object = TableGridDraw(my_table_grid)

           object.my_table_grid = my_table_grid;

        end

    end

end

function draw_onto( object, parent_handle )

%DRAW_ONTO Draws the controls onto the parent_handle.  This function needs

%to be called everytime an update happens.

%   This function draws the entire handle onto the handle.  This function

%   needs to be called everytime the back table is updated.  The class will

%   notify when its necessary.

    %Need to invert y, so need total size

    [x, y] = object.get_bounding_box();

    % First delete an extra controls

    assert( ~(size(object.controls, 2) > object.my_table_grid.width), 'Implment delete when necessary.');

    assert( ~(size(object.controls, 1) > object.my_table_grid.height), 'Implment delete when necessary.');

    if size(object.controls, 2) ~= object.my_table_grid.width || size(object.controls, 1) ~= object.my_table_grid.height

        object.controls(object.my_table_grid.height, object.my_table_grid.width) = 0;

            end

function [x, y] = get_bounding_box( object )

%GET_BOUNDING_BOX Gets the size in pixels of the grid.

%Returns the size of the grid (as a box) for layout purposes.

    x = object.my_table_grid.height; %Store number of cells first

    x = 120*x + 5*(x-1); %Then calculate the pixels.

    y = object.my_table_grid.height;

    y = 80*y + 5*(y-1); %Same here.
