Dear all, I couldn't run this code in MATLAB2015b, but it was working well before

uicontrol('Style', 'pushbutton', 'String', 'SAVE',...
        'Position', [20 20 50 20],...
        'Callback', ...
        @yourCallback);      % what do you want to do?
function yourCallback(ObjH, EventData)    
I = getimage;
setappdata(0, 'I', I);
resXGui;  %the name of the GUI where to transfer
clc

Error:Function with duplicate name "yourCallback" cannot be defined.

Does anyone knows how to make it work again for MATLAB2015b?

Regards, Meshoo

There is another function called "yourCallback" inside the M-file. Rename the function - I suggest to use meaningful names, because this reduces the chance for such collisions.

在 MATLAB Online 中打开

Provided that B_GUI is the figure handle of the target figure (or a uipanel or uitab on the target figure)

I = imread('cameraman.tif');
newfig = figure();
newax = axes('Parent', newfig);
Ih = imshow(newax, I);
cb = @(hObject, eventdata) imshow(axes('Parent', B_GUI), get(Ih, 'CData'))
bh = uicontrol('style', 'push', 'Parent', newfig, 'Callback', cb);
