Hello,
Is it possible to get a value from a checkbox in a non visible figure. What would be the right instruction to get its value?
HIM(1)= figure ( ... 'visible','off'),
creation of the checkbox cb(1)
Call the value of cb(1)
treatment_cb=get(cb(1),'value'); does not work
Thanks for your answer

Please explain "does not work" with any details. The command should work actually, so it is important, what exactly you observe.

get(chkBox, 'Value') as well as chkBox.Value should work with visible and invisible uifigures equally.
% Create invisible uifigure
hmi = uifigure('Visible', 'Off');
% add checkbox to uifigure
chkBox = uicheckbox(hmi);
% Message string for anonymous helper function
msgStr = 'Checkbox value before set:';
% Anonymous helper function printChkBoxStatus to print the checkbox status
printChkBoxStatus = @() fprintf('%s %d\n', msgStr, get(chkBox, 'Value'));
% print the checkbox status
printChkBoxStatus()
% set the checkbox status to true ("checked")
set(chkBox, 'Value', true);
% print the checkbox status again
printChkBoxStatus()

Hello,
Your code works.
I must have messed up my writing.
Thanks for your help
Sincerely
