Matlab GUI，使用靜態文本框的輸入並將其轉換爲基本按鈕

Question

我正在努力如何使用Matlab gui界面。

我不是在尋找答案，只是一些更多的指導如何做到這一點。

我想將編輯框中的溫度從F轉換爲C ...所以我想我需要方程式在按鈕中。

我想我被困在如何從編輯框傳遞數字到按鈕來轉換它，然後如何將它傳回，然後顯示它。 這是否有意義？

function varargout = ICA09A_TEMPFtoC(varargin) 
% ICA09A_TEMPFTOC MATLAB code for ICA09A_TEMPFtoC.fig 
%  ICA09A_TEMPFTOC, by itself, creates a new ICA09A_TEMPFTOC or raises the existing 
%  singleton*. 
% 
%  H = ICA09A_TEMPFTOC returns the handle to a new ICA09A_TEMPFTOC or the handle to 
%  the existing singleton*. 
% 
%  ICA09A_TEMPFTOC('CALLBACK',hObject,eventData,handles,...) calls the local 
%  function named CALLBACK in ICA09A_TEMPFTOC.M with the given input arguments. 
% 
%  ICA09A_TEMPFTOC('Property','Value',...) creates a new ICA09A_TEMPFTOC or raises  the 
%  existing singleton*. Starting from the left, property value pairs are 
%  applied to the GUI before ICA09A_TEMPFtoC_OpeningFcn gets called. An 
%  unrecognized property name or invalid value makes property application 
%  stop. All inputs are passed to ICA09A_TEMPFtoC_OpeningFcn via varargin. 
% 
%  *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one 
%  instance to run (singleton)".

有什麼我應該做的，以便讓任何人編輯這個更具可讀性？

Answer 1

要獲得在文本編輯框中輸入使用溫度：

tempF = get(handles.degF_et,'String'); 

這可以從按鈕的功能調用。

要更改顯示有使用的字符串：

set(handles.degF_et,'String','some string');
