MATLAB: How to call the Excel sheet values to use in another pushbutton_callback for another algorithm in GUI

guiusing excel data

To use my excel sheet values i had used the commands

[filename, pathname]=uigetfile
FileNameString=strcat(pathname, filename) %Same as FullFileName
Yourdata=xlsread(FileNameString)

now i want to use 'Yourdata' values in another pushbutton_callback in which i am using a for loop.

[filename, pathname]=uigetfile
FileNameString=strcat(pathname, filename) %Same as FullFileName
Yourdata=xlsread(FileNameString)
handles.Yourdata=Yourdata
guidata(hObject,handles)

To get your data from another object

Yourdata=handles.Yourdata

In the below, I really think you should be replacing max(video(1,1,1,:)) with size(video,4) as the number of frames to play depends on the data size not on the content of the pixels.

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)

if ~isfield('handles', 'active_player')
  handles.active_player = 0;
end
%go ahead and bash the active player: the other routines will detect the change

%and will quit running

handles.active_player = 1;
guidata(hObject, handles);
obj = VideoReader('supernewtable.mp4');
video = obj.read();
axes(handles.axes1);
fps=120;
for i=1:max(video(1,1,1,:))
    handles = guidata(hObject);
    if handles.active_player ~= 1; break; end
    imshow(video(:,:,:,i));
    pause(0.5/fps);
end
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
if ~isfield('handles', 'active_player')
  handles.active_player = 0;
end
%go ahead and bash the active player: the other routines will detect the change
%and will quit running
handles.active_player = 2;
guidata(hObject, handles);
obj = VideoReader('contgantry.mp4');
video = obj.read();
axes(handles.axes1);
fps=120;
for i=1:max(video(1,1,1,:))
    handles = guidata(hObject);
    if handles.active_player ~= 2; break; end
    imshow(video(:,:,:,i));
    pause(0.5/fps);
end

MATLAB: Link two pushbutton_Callback (hObject, eventdata, handles)

Hello Behzad,

If I'm understanding you correctly, you have two separate GUIs, each with their own button. When you push the "OK" button in the "Search" GUI, you want this to also execute the same code that would be run when you hit the "Load" button in the "myGUI" GUI.

One way to do this would be to simply have a separate M-file that contains the shared code you want to run. Both of the callbacks would simply call that separate function, and you wouldn't have to worry about giving access to methods of one GUI from the other. This method exposes more files/code to users though, and isn't very scalable.

Another possibility might be, if you create/open the "Search" GUI from "myGUI", you could pass the handle to the function you want to call in the constructor. Then, in the opening function of "Search", you can save that function handle to the "handles" guidata, and call it within the pushbutton callback.

Another way to do this would be to implement some kind of class-based system, where you make the shared code accessible to both classes (either making that method public, or using meta-class access specification). This would actually be easiest to do if you were using App Designer rather than GUIDE, since the GUIs are created as a class to start with. If you haven't gotten too far into your GUI development, consider it as an alternative.
