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

% --- 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);
% --- 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
numb=str2double(get(hObject,'string'));
if isnan(numb)
errordlg('请输入数字','输入错误','modal');
end
handles.numb=numb;
guidata(hObject, handles);
% --- 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)
