任务要求#xff1a;点击一次“100”按钮#xff0c;按钮上的文字值就递增1#xff1b;点击“close”按钮普通按钮静态文本和可编辑文本设计一个简易计算机 初步认识普通按钮
任务要求点击一次“100”按钮按钮上的文字值就递增1点击“close”按钮关闭所有窗口 命令行打开GUI命令行guide或者appdesigner 如果左边方块没有文字说明则点击文件-预设-在组件选项板中显示名称-确定 调整设计界面大小点击普通按钮拉到设计界面调整普通按钮大小 双击这个普通按钮或者右键点击属性修改String、FontSize等内容。修改完毕后点击×号退出 重复以上操作得到以下 点击保存命名为test1.fig同时自动生成test1.m文件 对于test1.m文件 **function varargout test1(varargin)**
% TEST1 MATLAB code for test1.fig
% TEST1, by itself, creates a new TEST1 or raises the existing
% singleton*.
%
% H TEST1 returns the handle to a new TEST1 or the handle to
% the existing singleton*.
%
% TEST1(CALLBACK,hObject,eventData,handles,...) calls the local
% function named CALLBACK in TEST1.M with the given input arguments.
%
% TEST1(Property,Value,...) creates a new TEST1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before test1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to test1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDEs Tools menu. Choose GUI allows only one
% instance to run (singleton).

function test1_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

function varargout test1_OutputFcn(hObject, eventdata, handles)
% varargout cell array for returning output args (see VARARGOUT);
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)% Get default command line output from handles structure
varargout{1} handles.output;% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)function varargout test1(varargin)函数名称即文件名称包含了方才设计的图形文件的一些初始化信息不要修改 function test1_OpeningFcn(hObject, eventdata, handles, varargin)回调函数当打开一个图形文件的时候所有的控件数据都设置好了之后把图形界面呈现在电脑屏幕之前该函数运行对界面进行一些初始化处理 function varargout test1_OutputFcn(hObject, eventdata, handles) 输出函数有输出参数在打开函数OpeningFcn()返回控制之后把控制权返回给命令行窗口之前执行该函数执行结果会输出到命令行窗口中 pushbutton1_Callback、pushbutton2_Callback两个组件的回调函数在图形界面点击按钮会执行对应回调函数其中的pushbutton1、pushbutton2对应组件的Tag function pushbutton1_Callback(hObject, eventdata, handles)
%hObject是点击对象的句柄即点击“100”按钮时会返回这个按钮的句柄
%以此来区分点击对象是“100”而不是“close”%eventdata是一个保留字段在不同的控件中有不同用法在按钮中其实是没什么意义的%handles是结构数组包含整个界面控件信息以及数据信息现在回到设计界面 给close按钮添加回调对“close”按钮点击右键查看回调单击callback会定位到.m文件中的对应位置进行代码编辑保存 % --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
clear all %清除所有变量
close all %关闭所有窗口点击.fig页面中的绿色三角形运行点击运行界面的“close”图形窗口就关闭了 给100按钮添加回调要求实现点击一次“100”按钮按钮上的文字值就递增1。步骤同上 % --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
%hObject是点击对象的句柄即点击“100”按钮时会返回这个按钮的句柄
%以此来区分点击对象是“100”而不是“close”
%eventdata是一个保留字段在不同的控件中有不同用法在按钮中其实是没什么意义的
%handles是结构数组包含整个界面控件信息以及数据信息%get(h,属性)获得图形对象h上的属性值是字符串格式
sget(hObject,string);%set(h,Name,Value) 使用一个或多个名称-值参数设置指定图形对象h的属性
set(hObject,string,num2str(str2num(s)1));静态文本和可编辑文本
任务要求实现在可编辑文本中输入文字回车立即显示在静态文本框中 可编辑文本可以输入内容 静态文本仅用于显示字符 界面设计如下属性不做修改保存为test2.fig 双击.fig页面中的可编辑文本点击查看回调点击callback 自动定位到.m文件中的edit1_Callback根据任务要求进行代码编辑 function edit1_Callback(hObject, eventdata, handles)
% hObject handle to edit1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)% Hints: get(hObject,String) returns contents of edit1 as text
% str2double(get(hObject,String)) returns contents of edit1 as a doublesget(hObject,string);
%handles包含整个界面控件信息以及数据信息
%**handles.text2即引用了另一个控件的数据text2是静态文本框的tag值**
set(handles.text2,string,s);handles可帮忙引用其他控件的数据 保存.m在.fig界面运行即可
设计一个简易计算机
普通按钮、静态文本和可编辑文本的综合运用 先用普通按钮设计属性只修改string 增加静态文本属性修改backgroungcolor防止和页面背景融为一体同时把string删除。该框用于显示计算过程和结果 编写各个普通按钮的回调函数任务要求把计算过程和结果在静态文本框中显示出来 0~9和、-、/的按钮 % --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% 如果只是
% sget(hObject,string);
% set(handles.text2,string,s);
% 则会导致无法输入11只能输入1
s0get(handles.text2,string);
sget(hObject,string);
set(handles.text2,string,[s0,s]);×的按钮×不能运算*才可以运算 % --- Executes on button press in pushbutton16.
function pushbutton16_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton16 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
s0get(handles.text2,string);
sget(hObject,string);
set(handles.text2,string,[s0,*]);和C的按钮 % --- Executes on button press in pushbutton18.
function pushbutton18_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton18 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
s0get(handles.text2,string);
%eval(expression)返回 expression 的输出数值型
set(handles.text2,string,num2str(eval(s0)));% --- Executes on button press in pushbutton19.
function pushbutton19_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton19 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
set(handles.text2,string,[]);
