confuse with the 'String' and 'Value' when I use the GUIDE to app designer migration tool

I change the fig code to the app designer code by using the GUIDE to app designer migration tool,and I need correct the code.But there is some code confused me :

    set(app.orderN_tag,'String',num2str(app.orderN));

I change the code to

app.orderN_tag.Value=num2str(app.orderN);

but there is another code

set(app.orderN_tag,'Value',  orderN);

what should I change the code to fit the app designer ?

What kind of component is app.orderN_tag?

Answer 1

[TAB]

String is the visiable name/lable of the control.

For example Button lable , Checkbox name lable etc.

Value is the numeric value of control based on its status.

For example if a Checkbox is selected is value 1, If Checkbox is not selected its value is 0.

See Type of Control > Value section at UIControl Properties

In addition to this: you can change the value that a checkbox returns if it is checked by changing the Max property.
