Try this. Assume Audi is the first entry in the car popup, which is on the left, and the popup on the right is for owners. So then do
audiOwners = {'Maria', 'Jhon'};
skodaOwners = {'Maria', 'Jhon', 'Nick'};
% Get car model
selectedCar = handles.popCar.Value;
% Fill owners popup with corresponding list of owners for that model of car.
if selectedCar == 1
% Fill owners popup with Audi owners.
handles.popOwners.String = audiOwners;
else
% Fill owners popup with Skoda owners.
handles.popOwners.String = skodaOwners;
end
If you really want the names in the edit text box instead of a drop down list, then have a loop
audiOwners = {'Maria', 'Jhon'};
skodaOwners = {'Maria', 'Jhon', 'Nick'};
% Get car model
selectedCar = handles.popCar.Value;
% Fill owners popup with corresponding list of owners for that model of car.
if selectedCar == 1
owners = audiOwners;
else
owners = skodaOwners;
end
% Fill owners popup with Audi owners.
str = [];
for k = 1 : length(owners)
str = fprintf('%s\n%s', str, owners{k});
end
handles.edtOwners.Max = 2; % I think you need this for it to allow a multi-line edit text box.
handles.edtOwners.String = str;
But I think it would be confusing for the user to have two dropdown lists, each with the name of only one kind of car.
