matlab-GUI程序(2)

1、GUI刚打开时要执行的,此时GUI的所有对象都已经建立

% --- Executes just before test1 is made visible.
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)
% varargin   command line arguments to test1 (see VARARGIN)

% Choose default command line output for test1
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes test1 wait for user response (see UIRESUME)
% uiwait(handles.figure1);

 

 
2、输出参数返回到命令行
% --- Outputs from this function are returned to the command line.

% --- Outputs from this function are returned to the command line.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;

 3、更新参数和输入参数

guidata(hObject, handles);

4、选择默认命令行

handles.output = hObject;

5、响应函数

% --- Executes on button press in btn_draw.
function btn_draw_Callback(hObject, eventdata, handles)
% hObject    handle to btn_draw (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)



function a_num_Callback(hObject, eventdata, handles)
% hObject    handle to a_num (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 a_num as text
%        str2double(get(hObject,'String')) returns contents of a_num as a double


% --- Executes during object creation, after setting all properties.
function a_num_CreateFcn(hObject, eventdata, handles)
% hObject    handle to a_num (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: edit controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end



function b_num_Callback(hObject, eventdata, handles)
% hObject    handle to b_num (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 b_num as text
%        str2double(get(hObject,'String')) returns contents of b_num as a double


% --- Executes during object creation, after setting all properties.
function b_num_CreateFcn(hObject, eventdata, handles)
% hObject    handle to b_num (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: edit controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end



function c_num_Callback(hObject, eventdata, handles)
% hObject    handle to c_num (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 c_num as text
%        str2double(get(hObject,'String')) returns contents of c_num as a double


% --- Executes during object creation, after setting all properties.
function c_num_CreateFcn(hObject, eventdata, handles)
% hObject    handle to c_num (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: edit controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end

 6、为3个文本框编写代码

 

function a_num_Callback(hObject, eventdata, handles)
% hObject    handle to a_num (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 a_num as text
%        str2double(get(hObject,'String')) returns contents of a_num as a double
numa=str2double(get(hObject,'string'));
if isnan(numa)
      errordlg('请输入数字','输入错误','modal');
end
handles.numa=numa;
guidata(hObject, handles);
