如何禁用图上的关闭按钮

Question

我想在Matlab中禁用图中的关闭按钮。 我该怎么做？

Answer 1

似乎您必须重写CloseRequestFcn事件处理程序，请参阅here。您不能隐藏或禁用关闭按钮，但可以确保用户点击它不会产生任何影响。

Answer 2

有了这个，你可以禁用所有：

set(findall(handles.your_uipanel, '-property', 'Enable'), 'Enable', 'off') 

但只禁用接近一个：这里

function closeRequestDemo 
    figHdl = dialog('Name','Close Request Demo',... 
        'CloseRequestFcn',@cmdClose_Callback);...dialog creates a nice stripped down figure 

    uicontrol('Parent',figHdl,... 
       'String','Close',... 
       'Callback',@cmdClose_Callback); 


    function cmdClose_Callback(hObject,varargin) 
     disp(['Close Request coming from: ',get(hObject,'Type')]); 

     %do cleanup here 
     delete(figHdl); 

    end %cmdClose_Callback 
end %closeRequestDemo

另一种方式是：

% Get all the handles to everything we want to set in a single array. 
handleArray = [handles.editText, handles.pushbutton, handles.listbox]; 
% Set them all disabled. 
set(handlesArray, 'Enable', 'off');
