How to generate 'N' number of pop-up windows in app design using MATLAB.

I'm creating an app in app designer using Matlab. in my case different Pop-up windows should be opened. For example, Number of girls = x, then x pop-up windows should be opened and inside pop-up window1,Girl1 = 'edit text value', similarly inside Pop-up window2, Girl2 = 'edit text value' and so on. In 'edit text value' i should be able to give some numeric value.

Hello Vaishnavi,

Based on the functionality you described, you can create a customized application using "uitabgroup" and "uitab"functions to generate and manage tabs, "uieditfield"function for input fields where users can enter text, and "uilabel"function to add descriptive text labels next to the input fields.

Below is a code snippet that dynamically creates tabs based on user input:

% App initialization and component creation
methods (Access = private)
    
    % Create UIFigure and components
    function createComponents(app)
        % Create UIFigure
        app.UIFigure = uifigure('Position', [100 100 640 480]);
        app.UIFigure.Name = 'My App';

        % Create TabGroup
        app.TabGroup = uitabgroup(app.UIFigure, 'Position', [20 80 600 380]);

        % Create EditField
        app.EditField = uieditfield(app.UIFigure, 'numeric', ...
            'Position', [20 20 100 22], ...
            'ValueChangedFcn', @(src, event) createTabs(app, src, event));
    end

    % Create tabs based on input value
    function createTabs(app, src, event)
        % Clear existing tabs
        delete(app.TabGroup.Children);

        % Get the input value from the EditField
        numTabs = app.EditField.Value;

        % Validate the input to be positive
        if numTabs < 1
            uialert(app.UIFigure, 'Please enter a positive number', 'Input Error');
            return;
        end

        % Create the specified number of tabs
        for i = 1:numTabs
            % Create a new tab
            tab = uitab(app.TabGroup, 'Title', ['Tab ' num2str(i)]);

            % Create an edit label and edit text in the tab
            editLabel = uilabel(tab, 'Text', 'Edit Label:', ...
                'Position', [50, 100, 100, 22]);

            editText = uieditfield(tab, 'text', 'Position', [150, 100, 100, 22]);
        end
    end
end

In the above code, "createTabs" is a custom function designed to dynamically generate a specified number of tabs within a tab group based on user input. Each tab created contains a 'Edit Label' and an adjacent editable text field, allowing for customized user interaction within each tab.

Below is the image of the app you received after executing the provided code snippet.

Thank u Vandit for the code. I have one difficulty in the execution. The Tabs are not updating for every new input. What changes are needed in code, so that the Tabs will be updated for every new input edit text

Hello Vaishnavi,

The code snippet provided above is already creating the tabs dynamically when the input field value is changed. If it is not working as expected, please double-check the event listener setup or share more details for further assistance.

[Virajita Parameswaran]

I do some changes. It's working now. Thank u so much for your help Vandit.
