matlab - 切换另一个按钮的 Matlab GUI 按钮

Question

有没有办法在 Matlab GUI 中创建两个切换按钮，以便一个切换另一个？换句话说，如果按钮 A 处于打开状态，我如何创建一个按钮 B，它在打开时会使 A 关闭？

Answer 1

这是我的代码：

function button1_Callback(hObject, eventdata, handles)
if get(hObject,'Value')==1

    %do something here

else

    %do something else (in my case delete a video object)

如果我现在放第二个按钮并使用命令

set(handles.button1,'Value',0)

The result is that my first button toggles but the command after the else is not executed. Is there a way to execute that command as well?

Answer 2

我有版本 R2009a，所以我不知道这是否适合您：

guide我用（默认名称）定义了两个按钮。单击第一个时，它被禁用（启用：关闭），其值设置为 1，其字符串设置为 On；第二个按钮被设置为另一个状态。另一个按钮也有类似的行为。

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
set(handles.pushbutton1,'Value',1,'String','On','Enable','Off')
set(handles.pushbutton2,'Value',0,'String','Off','Enable','On')
get(handles.pushbutton1)

% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
set(handles.pushbutton1,'Value',0,'String','Off','Enable','On')
set(handles.pushbutton2,'Value',1,'String','On','Enable','Off')

如果要根据 button1 的状态切换button2 的行为，请执行以下操作：

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)

% this toggles button1 between 0 and 1 and its label between 'On' and 'Off'
p = 1-get(handles.pushbutton1,'Value');   
set(handles.pushbutton1,'Value',p)
if p==0
    set(handles.pushbutton1,'String','Off')
else
    set(handles.pushbutton1,'String','On')
end



% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)

% Behavior of button2 is dependent on state of button1
p = get(handles.pushbutton1,'Value');

if p==0
    % Do this when button1 has its label to 'Off' (and Value to 0)
else
    % This will execute when button1 has a Value of 1 (and its label showing 'On')
end

这是你需要的吗？
