open_callback.m

matlab7.0从入门到精通(光盘内容)

function varargout = Open_Callback(h, eventdata, handles, varargin)
[filename, pathname] = uigetfile( ...
    {'*.mat', 'All MAT-Files (*.mat)'; ...
        '*.*','All Files (*.*)'}, ...
    'Select Address Book');
%选择Cancel则返回
if isequal([filename,pathname],[0,0])
    return
    %否则构造文件全路径并检查装载这些文件
else
    File = fullfile(pathname,filename);
    %如果MAT文件无效，不保存信息
    if Check_And_Load(File,handles)
        handles.LastFIle = File;
        guidata(h,handles)
    end
