Matlab gui returns 输出参数太快

Question

虽然我是一个相当中等的 matlab 用户，但我无法让我的 gui 工作。它的目的是让我使用一种单击方式来组织我的下载，但它 return 输出参数的方式太快了。代码如下：

function [answer]=makegui(files,season,episode)
close all
%% Initialize variables
% Input (if empty)
if nargin==0
    files{1}='Avengers';
    files{2}='NCIS';
    files{3}='Would I Lie to You';
    season{1}=1;
    season{2}=2;
    season{3}=3;
    episode{1}=11;
    episode{2}=22;
    episode{3}=24;
else
    if length(files)>length(season) || length(files)>length(episode)
        sprintf('Not enough filenames provided')
        delete(fig)
    end
end

width=450;
height=100+25*length(files);

% Function variables
checks=ones(1,length(files));

% Output variables
answer=[];
fig = figure('Name','Fili3','NumberTitle','off','Visible','off','Position',[360,500,width,height],'CloseRequestFcn',@temp); % Create figure

%% Declare buttons
all    = uicontrol('Style','checkbox',...
    'String','Select all','Position',[50,height-35,70,25],...
    'Callback',{@all_Callback},'Value',1);

for i=1:length(files)
    item{i}=uicontrol('Style','checkbox',...
        'String',files{i},'Position',[75,height-60-25*i,150,25],...
        'Callback',@item_Callback,'Value',1);
    uicontrol('Style','text','String',sprintf('%d',season{i}),...
        'Position',[320,height-60-25*i,25,25]);
    uicontrol('Style','text','String',sprintf('%d',episode{i}),...
        'Position',[370,height-60-25*i,25,25]);
end
uicontrol('Style','text','String','TV Show Name',...
    'Position',[90,height-60,60,15]);
uicontrol('Style','text','String','Season',...
    'Position',[300,height-60,60,15]);
uicontrol('Style','text','String','Episode',...
    'Position',[350,height-60,60,15]);
options = uicontrol('Style','popupmenu',...
    'String',{'Rename and Move','Rename','Move'},...
    'Position',[300,height-35,120,25],...
    'Value',1);
uicontrol('Style','pushbutton','String','Run',...
    'Position',[345,12,30,30],'Callback',@closefunction);

% Make UI visible
fig.Visible='on';
movegui(fig,'center')

%% Callback functions

    function all_Callback(source,eventdata)
        if source.Value
            checks=ones(1,length(files));
        else
            checks=zeros(1,length(files));
        end
        source.Value
        for j=1:length(files)
            item{j}.Value=source.Value;
        end
    end

    function item_Callback(source,eventdata)
        S=regexp(files,source.String);
        i=find(~cellfun(@isempty,S));
        checks(i)=source.Value;
        if source.Value==0
            all.Value=0;
        elseif source.Value==1 && sum(checks)==length(files)
            all.Value=1;
        end
    end

    function closefunction(source,eventdata)
        answer.checks=checks(:);
        answer.mode=options.Value;

        delete(fig)
    end

    function temp(source,eventdata)
        delete(fig)
    end
end

我添加了nargin部分，以便在测试时不必经常提供输入参数，后来我打算让运行按钮和关闭功能指向相同的class。我希望它 return 回答，但是如果你运行在你自己的计算机上这样做，你会看到它 return 在答案初始化后就立即回答，然后拒绝做任何事情否则。

这可能只是我忘记的一小段代码，但如果有人能为我指出正确的方向，那就太好了！

谢谢，汤姆

知道了！只需要添加 waitfor(fig).
