MATLAB新手 - 在弹出菜单

Question

我想在我的弹出菜单中添加元素，用户将其写入文本字段，我是matlab的新手，所以任何解释都非常感激，我知道它是关于回调的按钮，但我不知道该怎么做......

我的gui到目前为止：

到目前为止我的代码：

function varargout = popupmenu(varargin)

gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @popupmenu_OpeningFcn, ...
                   'gui_OutputFcn',  @popupmenu_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end


function popupmenu_OpeningFcn(hObject, eventdata, handles, varargin)

handles.output = hObject;


guidata(hObject, handles);





function varargout = popupmenu_OutputFcn(hObject, eventdata, handles) 

varargout{1} = handles.output;



function edit1_Callback(hObject, eventdata, handles)


function edit1_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end


function popupmenu1_Callback(hObject, eventdata, handles)


function popupmenu1_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end



function pushbutton1_Callback(hObject, eventdata, handles)

Answer 1

在pushbutton1_Callback您可以添加：

new_item=get(handles.edit_1,'string') % to get the string from the edit box
tmp=get(handles.popupmenu1,'string') % to get the actual list of items in the popup menu
tmp{end+1}=new_item % to add the string
set(handles.popupmenu1,'string',tmp) % to update the popup menu items
