Question

matlab gui界面设置。

% --------------------------------------------------------------------
function open_Callback(hObject, eventdata, handles)
% hObject handle to open (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[filename.pathname]=uigetfile('*.jpg')
set (handles.edit1,'string',[pathname,filename]);
file=get(handles.edit1,'string');
A=imread(file);
axes(handles.axes1);
imshow(A);

出现以下错误为什么？
filename =
pathname: '5f8e340djw1dqtwco2akdj.jpg'
??? Reference to non-existent field 'edit1'.
Error in ==> untitled>open_Callback at 84
set (handles.edit1,'string',[pathname,filename]);

Answer 1

你的edit1 在fig中没有画，也就是程序报错说没有找到edit1

Answer 2

按照错误说明，检查Tag值是否为edit1
