篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Matlab GUI 菜单设计相关的知识,希望对你有一定的参考价值。
界面布局的设计我已经会了,关键是如何实现在界面的框架下的菜单选项的回调,即当点击菜单的某个选项后有相应的操作!比方说点击“打开”,可以打开任意文件下的图像,有程序的可以帮忙吗
参考技术A 比方说点击“打开”,可以打开任意文件下的图像,有程序的可以帮忙吗 ??% --- 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)
global im
[filename pathname] = ...
uigetfile('*.jpg';'*.bmp';'*.gif', '开始');
str=[pathname filename];
im=imread(str);
axes(handles.axes1);
imshow(im);本回答被提问者和网友采纳 参考技术B 点击菜单的某个选项后有相应的操作
你在菜单编辑器中增加一个菜单后,界面上会有相对应的Tag,下面有个Callback和一空行,点击空行右边的View即可进入M文件编辑器,在下面编程即可。

下面是我自己做的matlab环境下的图形处理小工具。
聊生于无。配合Guid一起用。
function varargout = dazuoye(varargin) % DAZUOYE MATLAB code for dazuoye.fig % DAZUOYE, by itself, creates a new DAZUOYE or raises the existing % singleton*. % % H = DAZUOYE returns the handle to a new DAZUOYE or the handle to % the existing singleton*. % % DAZUOYE(‘CALLBACK‘,hObject,eventData,handles,...) calls the local % function named CALLBACK in DAZUOYE.M with the given input arguments. % % DAZUOYE(‘Property‘,‘Value‘,...) creates a new DAZUOYE or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before dazuoye_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop.
