save_callback.m

详细的介绍MATLAB 7 的功能

function varargout = Save_Callback(h, eventdata, handles, varargin)
%获取被选菜单的Tag属性
Tag = get(h,'Tag');
%获取address数组
Addresses = handles.Addresses;
%根据所选项执行相应的行为
switch Tag
case 'Save'
    %保存到默认的地址簿文件中
    File = handles.LastFile;
    save(File,'Addresses')
case 'Save_As'
    %允许用户选择要保存的目标文件名
    [filename, pathname] = uiputfile( ...
        {'*.mat';'*.*'}, ...
        'Save as');	
    %如果选择了Cancel则返回
    if isequal([filename,pathname],[0,0])
        return
    else
        %构造全路径名并保存
        File = fullfile(pathname,filename);
        save(File,'Addresses')
        handles.LastFile = File;
        guidata(h,handles)
    end
