Question

我正在研究matlab gui。我必须在点击当前gui的按钮时再调用另一个gui。但我必须传递一些值，如图像和文本字符串，从当前的gui到新的gui。我怎样才能做到这一点。我只是打开新的gui而不传递任何信息。

function pushbutton8_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton8 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
warning off;
choice = questdlg('Would you really want to goto next window ?', ...
    'RESET Dialog', ...
    'YES','NO','');

switch choice
    case 'YES'
        clc;clear all;close all;subpart;
    case 'NO'

end

让我们假设您要通过存储在句柄中的名为myData的结构传递所需的所有数据。然后，您只需简单地致电

function pushbutton8_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton8 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
warning off;
choice = questdlg('Would you really want to goto next window ?', ...
    'RESET Dialog', ...
    'YES','NO','');

switch choice
    case 'YES'
        mySecondGUI(handles.myData);
        delete(hObject);
    case 'NO'

end

这样，您的第二个GUI就会收到该信息。您要做的第二件事是在第二个gui中修改您的Opening函数：

mySecondGUID_OpeningFcn(hObject, eventdata, handles, varargin)

handles.theDataFromFirstGUI = varargin{1};

% ... Any initialisationstuff

guidata(hObject,handles);

如果您遇到旧gui无法正确关闭的问题，建议您阅读有关uiwait和uiresume的文章：https://www.mathworks.com/help/matlab/ref/uiwait.html
