[英]How do I show different images with radio buttons in matlab GUIDE?
這是截至目前的所有代碼。 更改按鈕組中的選定按鈕時會顯示正確的圖像,但在更改選定按鈕之前不會顯示圖像。 我希望第一個圖像是 FloorPlan{1},正如它在軸 1_CreateFcn 中所說的那樣,但它不起作用。 在您更改按鈕之前,軸根本不存在。
function varargout = selectfloorplan(varargin)
% SELECTFLOORPLAN MATLAB code for selectfloorplan.fig
% SELECTFLOORPLAN, by itself, creates a new SELECTFLOORPLAN or raises the existing
% singleton*.
%
% H = SELECTFLOORPLAN returns the handle to a new SELECTFLOORPLAN or the handle to
% the existing singleton*.
%
% SELECTFLOORPLAN('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SELECTFLOORPLAN.M with the given input arguments.
%
% SELECTFLOORPLAN('Property','Value',...) creates a new SELECTFLOORPLAN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before selectfloorplan_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to selectfloorplan_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

圖形對象的 ID 存儲在 GUIDE 存儲並在回調之間傳遞的handles
結構中。 axis1
不能作為輸入工作的原因是它沒有在回調函數的范圍內定義,所以函數無法解決它。 這就是為什么您的全球解決方法“解決”了問題。
如果替代handles.axes1
(或任何你軸對象標簽)為axis1
在axes()
調用,它應該執行為您期望。
