### MATLAB App Designer 示例代码及教程
#### 创建简单的应用程序界面
在MATLAB中创建一个新的App Designer项目非常简单。通过图形化界面拖放各种UI组件来构建应用布局。
```matlab
% 运行此命令打开新的空白App Designer窗口
appdesigner
```
#### 添加基本控件并设置回调函数
下面是一个简单的例子,展示了如何向应用程序添加按钮和文本框,并定义当点击按钮时触发的动作[^1]:
```matlab
classdef HelloWorldApp < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
Button matlab.ui.control.Button
EditField matlab.ui.control.EditField
end
% Callbacks that handle component events
methods (Access = private)
% Button pushed function: Button
function ButtonPushed(app, event)
value = app.EditField.Value;
disp(['You entered: ',value]);
end
end
% Component initialization
methods (Access = private)
% Create UIFigure and components
function createComponents(app)
% Create UIFigure and hide until all components are created
app.UIFigure = uifigure('Visible', 'off');
app.UIFigure.Position = [100 100 348 279];
app.UIFigure.Name = 'UI Figure';
% Create Button
app.Button = uibutton(app.UIFigure, 'push');
app.Button.ButtonPushedFcn = {@ButtonPushed, app};
app.Button.Position = [116 154 100 22];
app.Button.Text = 'Display Text';
% Create EditField
app.EditField = uieditfield(app.UIFigure, 'text');
app.EditField.Position = [116 194 100 22];
% Show the figure after all components are created
app.UIFigure.Visible = 'on';
end
end
% App creation and deletion
methods (Access = public)
% Construct app
function app = HelloWorldApp
% Create and configure components
createComponents(app);
% Register the app with App Designer
registerApp(app, app.UIFigure);
if nargout == 0
clear app
end
end
% Code that executes before app deletion
function delete(app)
% Delete UIFigure when app is deleted
delete(app.UIFigure);
end
end
end
```
这段代码实现了最基础的应用程序框架,在其中包含了两个主要元素——一个用于输入文字的编辑字段和一个用来显示所输入内容的按钮。每当用户按下该按钮时就会调用`ButtonPushed()`方法并将编辑框中的值打印到命令窗中。
#### 发布和部署应用程序
完成开发之后,可以通过打包工具将应用程序转换成独立可执行文件或其他形式分发给其他没有安装MATLAB环境的人运行[^2]。
#### 用户界面优化技巧
除了功能实现外,还可以利用组合、对齐等功能进一步美化用户界面,使整体看起来更加整洁美观。
