Question

我目前正在为已经完成的m.file开发GUI。 GUI将是一个具有多个页面的GUI，每个页面都是一个GUI。

在主GUI上，用户将在具有2个选项的单选按钮组上进行选择。根据选择，页面顺序将是Master GUI＆gt; GUI1＆gt; GUI2＆gt; GUI3或Master GUI＆gt; GUI1＆gt; GUI4＆GT; GUI5。

参考“http://matlabbyexamples.blogspot.sg/2011/10/multipages-gui-forms-combining-from.html”中的示例，我以某种方式使其工作，我能够按照预期在页面之间导航。

现在的问题是，每次我返回主GUI以更改单选按钮组上的选择时，它将重新打开所有GUI并关闭其可见性以再次隐藏它们（基本上是程序在我先打开它，这不是我想要的。作为一名新的MATLAB用户，我不知道为什么会这样。

以下是我的主gui的代码段：

function varargout = StartPage(varargin)
% STARTPAGE MATLAB code for StartPage.fig
%      STARTPAGE, by itself, creates a new STARTPAGE or raises the existing
%      singleton*.
%
%      H = STARTPAGE returns the handle to a new STARTPAGE or the handle to
%      the existing singleton*.
%
%      STARTPAGE('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in STARTPAGE.M with the given input arguments.
%
%      STARTPAGE('Property','Value',...) creates a new STARTPAGE or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before StartPage_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to StartPage_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

如果有人能让我知道我做错了什么并且还能为我提供解决方案，我会非常感激。

您可以使用以下文件交换程序（uiremember/uirestore）来跟踪gui中的上一次更改。此外，您可以通过使用“保存状态”例程[{3}}填充figure_closeRequestFcn()（或任何返回按钮回调）来实现此功能。
