MATLAB多页面GUI查询

Question

我目前正在开发一个GUI，用于一个我已经完成的m.file。该GUI将包含多个页面，每个页面都是自己的GUI。

在主GUI上，用户将在一个具有2个选项的单选按钮组中进行选择。根据所选内容，页面顺序将为Master GUI > GUI1 > GUI2 > GUI3或Master GUI > GUI1 > GUI4 > GUI5。

参考“http://matlabbyexamples.blogspot.sg/2011/10/multipages-gui-forms-combining-from.html”中的示例，我设法使其正常工作，我能够按预期从一页导航到另一页。

问题在于，每次我返回主GUI更改单选按钮组上的选择时，它都会重新打开所有GUI并关闭它们的可见性以再次隐藏它们（基本上是在我第一次打开程序时程序所做的），这不是我想要的。作为一名新的MATLAB用户，我不知道为什么会出现这种情况。

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)".

如果有人能告诉我我做错了什么，并提供解决方案，我将非常感激。

你可以使用以下文件交换程序（uiremember/uirestore），它会跟踪您的gui中的最后更改。此外，您可以通过在figure_closeRequestFcn()（或任何返回按钮回调）中填充“保存状态”例程来实现此功能，如此处所述。

让我重新阐述我的问题。当我运行上面发布的代码时，它会打开所有其他涉及的GUI页面，然后通过将它们的可见性设置为“关闭”来隐藏它们。然后我可以在PV或混合之间进行选择并访问我想要的GUI。但是，当我再次返回到主GUI（不是通过关闭GUI，而是有一个返回按钮），并选择另一个选项时，程序将像我第一次运行代码时那样打开所有涉及的GUI并隐藏它们的可见性。我希望避免每次进行选择时都必须打开和隐藏GUI。 - Zhi Cong Chan

在这种情况下，使用一个 if 语句是否有帮助？if strcmp(get(handles.s1,'Visible'),'on') then。 - marsei

那我该比较什么呢？我对MATLAB GUI真的一窍不通。 - Zhi Cong Chan
