1대 n으로 대응을 시키는 방법이 있나요?

https://kr.mathworks.com/help/matlab/ref/uilistbox.html#bui0qid

위 예제를 보고 참고하며 코드를 작성하고 있는데

function dataselection

fig = uifigure('Position',[100 100 350 275]);

% Create Numeric Edit Field

ef = uieditfield(fig,'numeric',...

'Position',[125 90 100 22]);

% Create List Box

lbox = uilistbox(fig,...

'Items', {'Freezing', 'Warm', 'Hot', 'Boiling'},...

'ItemsData', [0, 25, 40, 100],...

'Position',[125 120 100 78],...

'ValueChangedFcn', @selectionChanged);

% ValueChangedFcn callback

function selectionChanged(src,event)

% Display list box data in edit field

ef.Value = src.Value;

end

end

위 코드에서

'Items', {'Freezing', 'Warm', 'Hot', 'Boiling'},...

'ItemsData', [0, 25, 40, 100],...

items와 itemsdata는 1대1로 대응이 되는데 예를들어서

freezing - 0,1,2,3,4

warm - 20,21,22,23,24,25,26,27

과 같이 하나의 item에 여러개의 itemdata를 대응시킬수 있을까요?

Directly it is not possible to achieve this 1 to n mapping from the function of uilistbox itself.

But you can have a look at the below demo script which can be a possible work around.

function dataselection
fig = uifigure('Position',[100 100 350 275]);

% Create Numeric Edit Field
ef = uitextarea(fig,...
    'Position',[125 90 100 22],...
    'Value','');

% Create List Box
lbox = uilistbox(fig,...
    'Items', {'Freezing', 'Warm', 'Hot', 'Boiling'},...
    'ItemsData', ['F', 'W', 'H', 'B'],...
    'Position',[125 120 100 78],...
    'ValueChangedFcn', @selectionChanged);

% ValueChangedFcn callback
function selectionChanged(src,event)
    % Display list box data in edit field
    switch src.Value
        case 'F'
            val = {'0' '1' };
        case 'W'
            val = {'20' '21'};
        case 'H'
            val = {'45' '46'};
        case 'B'
            val = {'100' '101'};
    end
    ef.Value = val;
end

end
