Matlab对话框总结

选择获取文件路径对话框

selpath = uigetdir(path,'我是标题')

注：path可以指定默认打开的文件路径，path若为空，则打开当前文件路径

输入信息参数对话框

prompt = {'Enter matrix size:','Enter colormap name:'};
title = 'Input';
dims = [1 35];		
definput = {'20','hsv'};
answer = inputdlg(prompt,title,dims,definput)

注：这里返回的参数是cell格式，如果想调用数值的话，需要转换一下

user_val = str2num(answer{1})

按钮选择问题对话框

answer = questdlg('Would you like a dessert?', ...
	'Dessert Menu', ...
	'Ice cream','Cake','No thank you','No thank you');
% 最后的'No thank you'为默认选择

注：当然可以根据用户选择做出不同的响应

% Handle response
switch answer
    case 'Ice cream'
        disp([answer ' coming right up.'])
        dessert = 1;
    case 'Cake'
        disp([answer ' coming right up.'])
        dessert = 2;
    case 'No thank you'
        disp('I''ll bring you your check.')
        dessert = 0;
end

输出消息对话框

f = msgbox('Operation Completed','Success');

f = msgbox('Invalid Value', 'Error','error');

注:还可以在对话框中添加其他小图标或者自定义图片

警告信息对话框

f = warndlg('Pressing ACCEPT clears memory','Warning');

列表选择对话框

list = {'Red','Yellow','Blue',...                   
'Green','Orange','Purple'};
[indx,tf] = listdlg('ListString',list);

注：indx为用户选择的选项在数组中的索引
tf是一个逻辑值，如果用户点取消则为0，否则是1
