udemy(参考に記載)でC#のCompositePatternを聴講し、普段使っているMatlabのAppDesignerに実装してみた。
仕様
末端のエリアを選択した状態でAlertをクリック→その末端エリアを含む親エリアも警報状態とする。
任意のエリアを選択した状態でReleaseをクリック→子エリアすべての警報を解除する。
末端エリアを選択した状態で警報状態にはできない（一括警報は禁止）。
フォルダ階層
Main GUI
Tree1つとPushButton２つの構成

methods (Access = private)
% TreeにNodeを追加

end
node.NodeData = area;
children = area.GetChildren();
for i_node = 1:numel(children)
app.AddNode(children{i_node}, node);
end
end
% Icon変更の再帰処理
function SetImage(app)

子階層を持てるフォルダーのようなクラス
BlockArea.m
classdef BlockArea < AreaBase
properties (SetAccess = private, GetAccess = private)
areas_ cell
end
methods (Access = public, Sealed = true)
function this = BlockArea(kaisouEntity)

end
function Release(this)
for i_area = 1:numel(this.areas_)
this.areas_{i_area}.Release();
end
end
function out = GetCondition(this)
for i_area = 1:numel(this.areas_)

out = Condition.Alert;
return
end
end

end
function out = GetChildren(this)

子階層を持てないファイルのようなクラス

classdef Condition

Normal時のIcon (green.png)
Alert時のIcon (red.png)
