GUI题库

2.GUI编程

在第一个窗口中设置一个列表框,里面有内容:张三、李四、王五、赵六(分四行)。若双击某行，则弹出第二个窗口，显示选中的内容，按返回按钮，则回到第一个窗口。

代码

%mainfig.m

function listbox1_Callback(hObject, eventdata, handles)

% hObject handle to listbox1 (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

% Hints: contents = get(hObject,'String') returns listbox1 contents as cell array

% contents{get(hObject,'Value')} returns selected item

from listbox1

global str;

if isequal(get(gcf,'SelectionType'),'open')

n=get(hObject,'value');

str_all=get(hObject,'string');

str=str_all{n};

set(gcf,'Visible','off');

nextfig('Visible','on');

end

% --- Executes during object creation, after setting all properties.

%nextfig.m

function nextfig_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 nextfig (see VARARGIN)

% Choose default command line output for nextfig

handles.output = hObject;

global str

set(handles.edit1,'String',str);

% Update handles structure

guidata(hObject, handles);

% UIWAIT makes nextfig wait for user response (see UIRESUME)

% uiwait(handles.figure1);

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

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) set(gcf,'Visible','off');

mainfig('Visible','on');

3.设计一个GUI界面如下:

输入姓名,选中性别,选中民族,点击提交按钮,将选中的内容在静态文本框中显示。

代码见zhuce.fig,zhuce.m

function radiobutton1_Callback(hObject, eventdata, handles)

% hObject handle to radiobutton1 (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA) set(handles.radiobutton1,'value',1);

set(handles.radiobutton2,'value',0);

% Hint: get(hObject,'Value') returns toggle state of radiobutton1

function radiobutton2_Callback(hObject, eventdata, handles)

% hObject handle to radiobutton2 (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA) set(handles.radiobutton1,'value',0);

set(handles.radiobutton2,'value',1);

% Hint: get(hObject,'Value') returns toggle state of radiobutton2

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) a=get(handles.edit1,'String');

if get(handles.radiobutton1,'value')

b=get(handles.radiobutton1,'String');

elseif get(handles.radiobutton2,'value')

b=get(handles.radiobutton2,'String');

end

val=get(handles.listbox1,'Value'); str=get(handles.listbox1,'String'); c=str{val};

d=strcat(a,b);

e=strcat(d,c);

set(handles.text5,'String',e); guidata(hObject,handles);
