I want to get the data of the checkbox values when i clicked on the submit button, presently just the callback is executed but not able to get the values of the checkbox -
get(bg1_cb,'Values) will give the cell values
but when inside the call back execution function, i am not able to retreive the values from the checkbox which i need to pass to OutputData varaible. which is the output function.
function OutputData = AlgRun_Test
%% Intial Variables
S1_Alg = {'Test1','Test2','Test3','Test4','Test5','Test6','Test7'};
%% Create Figure and its Properties
Fig_Left = 200;
Fig_Bottom = 100;
Fig_Width = 210;
Fig_Height = 450;
f = figure('units','pixels','position',[Fig_Left,Fig_Bottom,Fig_Width,Fig_Height],...
'toolbar','none','menu','none');
set(f,'Name','User Algorithm Selection');
set(f,'NumberTitle','off');
%% CheckBox Selection
Left_Next = 5;
if true
G1_Left = Left_Next;
G1_Bottom = 95;
G1_Width = 200;
G1_Height = 350;
bg1 = uibuttongroup('Visible','on','units','pixels',...
'Title','Test Selection','Tag','BG1',...
'Position',[G1_Left G1_Bottom G1_Width G1_Height]);
for i = 1:length(S1_Alg)
% Create three radio buttons in the button group
bg1_cb(i) = uicontrol(bg1,'Style','checkbox',...
'String',S1_Alg{i},'Tag',['BG1_CB' num2str(i)],...
'Position',[10 300-(i-1)*30 200 30],...
'HandleVisibility','off');
end
Left_Next = G1_Left+G1_Width+10;
Pre_Width = G1_Left+G1_Width-10;
end
%% User Confirmation
if true
G4_Left = 5;
G4_Bottom = 15;
G4_Width = Pre_Width;
G4_Height = 75;
bg4 = uibuttongroup('Visible','on','units','pixels',...
'Title','Confirm Selection','Tag','BG4',...
'Position',[G4_Left G4_Bottom G4_Width G4_Height],...
'SelectionChangedFcn',@pbselection);
bg4_pb(1) = uicontrol(bg4,'Style','pushbutton',...
'String','Submit','Callback',@submitcb,...
'Position',[(G4_Width/8) 20 50 30],...
'HandleVisibility','off');
bg4_pb(2) = uicontrol(bg4,'Style','pushbutton',...
'String','Cancel',...
'Position',[((G4_Width/2)+G4_Width/8) 20 50 30],...
'HandleVisibility','off');
end
%% Returning the User Selection Data Back
x = 0;
function pbselection(source,eventdata)
disp(['Previous: ' event.OldValue.String]);
disp(['Current: ' event.NewValue.String]);
disp('------------------');
end
function submitcb(source,event) %(hObject, event, handles)
OutputData = 0;
end
end

You need to pass the handle of your checkboxes to your submitcb to access the values.
First add those handles as additional input to your callback:
bg4_pb(1) = uicontrol(bg4,'Style','pushbutton',...
'String','Submit','Callback',{@submitcb,bg1_cb},... %<-----
'Position',[(G4_Width/8) 20 50 30],...
'HandleVisibility','off');
Then edit your callback:
function submitcb(source,event,cb) %cb are your checkbox handles
for i=1:7
OutputData=cb(i).Value %do something with them
end
end
