Reading MATLAB Text Box Content: Methods

In MATLAB, you can create a text box using the uicontrol function and read the content of the text box using the get function.

Here is an example code that demonstrates how to create a text box and retrieve its content:

% 创建一个图形界面窗口
figure;

% 创建一个文本框
text_box = uicontrol('Style', 'edit', 'Position', [50, 50, 200, 30]);

% 创建一个按钮,用于触发读取文本框内容的操作
button = uicontrol('Style', 'pushbutton', 'String', '读取文本框内容', 'Position', [100, 10, 150, 30],...
    'Callback', {@read_text_box, text_box});

% 定义回调函数,用于读取文本框内容
function read_text_box(src, event, text_box)
    % 使用get函数读取文本框内容
    content = get(text_box, 'String');
    
    % 在命令窗口中显示文本框内容
    disp(content);
end

After running the above code, a graphical interface window will pop up, containing a text box and a button. When the button is clicked, the content from the text box will appear in the command window.
