핵심코드

 

1) Properties (Access = Private)

 

프로그램 코드 작성 시 사용할 변수 선언


    properties (Access = private)
        Data
    end

 

2) methods (Access = Private)

 

2-1) 수정이 가능한 형태

        function enableForm(app)
            app.NameEditField.Enable = 'on';
            app.AgeEditField.Enable = 'on';
            app.GenderDropDown.Enable = 'on';
            app.HealthStatusDropDown.Enable = "on";
            app.SmokerCheckBox.Enable = 'on';
            app.NameEditFieldLabel.Enable = "on";
            app.AgeEditFieldLabel.Enable = 'on';
            app.GenderDropDownLabel.Enable = 'on';
            app.HealthStatusDropDownLabel.Enable = "on";
        end
        

 

2-2) 수정이 불가능한 형태

          function disableForm(app)
            app.NameEditField.Value = '';
            app.AgeEditField.Value = 0;
            app.GenderDropDown.Value = 'Male';
            app.HealthStatusDropDown.Value = "Excellent";
            app.SmokerCheckBox.Value = false;

            app.NameEditField.Enable = "off";
            app.AgeEditField.Enable = 'off';
            app.GenderDropDown.Enable = 'off';
            app.HealthStatusDropDown.Enable = "off";
            app.SmokerCheckBox.Enable = 'off';

            app.NameEditFieldLabel.Enable = "off";
            app.AgeEditFieldLabel.Enable = 'off';
            app.GenderDropDownLabel.Enable = 'off';
            app.HealthStatusDropDownLabel.Enable = "off";
            app.SmokerCheckBox.Enable = 'off';
        end

 

3) Callback Function

 

3-1) 앱이 시작될 때 데이터 로딩 및 초기화를 수행하는 기능


        function startupFcn(app)
            t = readtable("patients.xls");

            patients = t(strcmp(t.Location, app.CountyGeneralHospitalNode.Text) & t.Smoker & t.Age >44, "LastName");
            for j = 1:size(patients, 1)
                lastname = char(patients{j, 'LastName'});
                uitreenode(app.CountyGeneralHospitalNode, "Text", lastname);
            end

            patients = t(strcmp(t.Location, app.StMarysMedicalCenterNode.Text) & t.Smoker & t.Age >44, "LastName");
            for j = 1:size(patients, 1)
                lastname = char(patients{j, 'LastName'});
                uitreenode(app.StMarysMedicalCenterNode, "Text", lastname);
            end

            patients = t(strcmp(t.Location, app.VAHospitalNode.Text) & t.Smoker & t.Age >44, "LastName");
            for j = 1:size(patients, 1)
                lastname = char(patients{j, 'LastName'});
                uitreenode(app.VAHospitalNode, "Text", lastname);
            end

            t.Properties.RowNames = t.LastName;
            app.Data = t;
        end

 

3-2) 트리(Tree)의 선택이 변경될 때 호출되는 함수


        function TreeSelectionChanged(app, event)
            selectedNode = app.Tree.SelectedNodes;
            hospitals = {'County General Hospital','St. Mary''s Medical Center','VA Hospital'};
            if ~isempty(find(strcmp(selectedNode.Text, hospitals), 1))
                disableForm(app);
            else
                enableForm(app);
            end

            patientName = selectedNode.Text;

            if isempty(selectedNode.Children)
                data = app.Data(patientName,:);

                if ~isempty(data)
                    app.NameEditField.Value = patientName;
                    app.AgeEditField.Value = data.Age;
                    app.SmokerCheckBox.Value = data.Smoker;
                    app.GenderDropDown.Value = char(data.Gender);
                    app.HealthStatusDropDown.Value = char(data.SelfAssessedHealthStatus);
                end
            end
        end

 

3-3) Age가 변경될 때 호출되는 함수


        function AgeEditFieldValueChanged(app, event)
            confirm = uiconfirm(app.UIFigure, "Change Patient Age?","Confirm Change");

            patientName = app.Tree.SelectedNodes.Text;
            if strcmp(confirm, "OK")
                app.Data.Age(patientName) = app.AgeEditField.Value;
            else
                app.AgeEditField.Value = app.Data.Age(patientName);
            end
        end

 

 

3-4) Smoker가 변경될 때 호출되는 함수


        function SmokerCheckBoxValueChanged(app, event)
            confirm = uiconfirm(app.UIFigure, "Change Smoker Status?","Confirm Change");

            patientName = app.Tree.SelectedNodes.Text;
            if strcmp(confirm, "OK")
                app.Data.Smoker(patientName) = app.SmokerCheckBox.Value;
            else
                app.SmokerCheckBox.Value = app.Data.Smoker(patientName);
            end
        end

 

.

3-5) Health Status가 변경될 때 호출되는 함수


        function HealthStatusDropDownValueChanged(app, event)
            confirm = uiconfirm(app.UIFigure, "Change Health Status?","Confirm Change");

            patientName = app.Tree.SelectedNodes.Text;
            if strcmp(confirm, "OK")
                app.Data.SelfAssessedHealthStatus(patientName) = app.HealthStatusDropDown.Value;
            else
                app.HealthStatusDropDown.Value = app.Data.SelfAssessedHealthStatus(patientName);
            end
        end

 

 

3-6) Gender가 변경될 때 호출되는 함수


        function GenderDropDownValueChanged(app, event)
            confirm = uiconfirm(app.UIFigure, "Change Patient Gender?","Confirm Change");

            patientName = app.Tree.SelectedNodes.Text;
            if strcmp(confirm, "OK")
                app.Data.Gender(patientName) = app.GenderDropDown.Value;
            else
                app.GenderDropDown.Value = app.Data.Gender(patientName);
            end
        end
