By using the Layout editor you create just a template, a recipe if you will, for creating a window or a widget that will have that layout and those fields. It is a definition, speaking in C terms. You need a declaration.

Let�s say you named your template TestLayout. Now you can create a concrete layout by appending "With" to the name of the template:

class testWindows: WithTestLayout<TopWindow>

Now you have a class with that layout and it will contain your "btnOK". Yet you can search in the code and you won�t find that explicit declaration anywhere.

In one of your methods from the class, usually the constructor, you can say:

btnOK=callback(btnOKClick);

Or if you want to use a less OOP approach, you can do:

WithTestLayout<StaticRect> b;
b.btnOk=callback...

Notice this time I used StaticRect. You can apply the layout to anything you want, including Buttons, EditFields and every existing widget, including your own if you have written any custom widgets.

PS: Don't forget to call CtrlLayout. Without it you layout will appear null.
I hope you�ll have more success with layouts in the future. Very powerful once you get used to them.
