在matlab中生成多级GUI表单

Question

让我们考虑下面的图片

这是代码

function varargout = example(varargin)
% EXAMPLE MATLAB code for example.fig
%      EXAMPLE, by itself, creates a new EXAMPLE or raises the existing
%      singleton*.
%
%      H = EXAMPLE returns the handle to a new EXAMPLE or the handle to
%      the existing singleton*.
%
%      EXAMPLE('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in EXAMPLE.M with the given input arguments.
%
%      EXAMPLE('Property','Value',...) creates a new EXAMPLE or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before example_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to example_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @example_OpeningFcn, ...

if nargin && ischar(varargin{1})

% --- Executes just before example is made visible.
function example_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to example (see VARARGIN)

% Choose default command line output for example
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes example wait for user response (see UIRESUME)
% uiwait(handles.figure1);


% --- Outputs from this function are returned to the command line.
function varargout = example_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;


% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)


% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

我需要的是：例如我创建了两个程序，其中一个将要求用户输入一些数据并生成信号，第二个将绘制它或计算功率谱，所以当我点击操作A时，它应该允许我输入信息并生成信号，第二个应该估计现有信号的功率谱，我该怎么办呢？提前谢谢

Answer 1

您可以编写另一个GUI，例如OperationA。然后，您可以在原始GUI中从pushbutton1_Callback调用它。您还可以使用：

来输入\ output参数

varargout = OperationA(varargin);

要记住的几件事：
然后入口点在OperationA_OpeningFcn。使用该函数中的输入参数执行您需要做的事情（例如，将它们存储在handles中） 2.您应该在uiwait(handles.figure1);中取消注释OperationA_OpeningFcn 3.分配任何输出参数并关闭OperationA_OutputFcn处的GUI 4.到OperationA_OutputFcn使用uiresume（例如在OK按钮的回调中）。
