I have noticed that the

btnOpen <<= THISBACK(myCallback);

works only for members of the class. While if you want have access to a function out the class you must use

btnOpen.WhenAction = callback(OpenDialog);

Correct. Also, you can call callback of another instance.

btnOpen.WhenAction = callback(object_ptr, &ObjectClass::Method)

Note that Ctrl::WhenAction can also be assigned using '<<=':

btn <<= callback(OpenDialog);

How to create a non modal dialog?

Make it a member of your main window class - that way it will not be closed at the and of scope by destructor (you will have to add code for closing it as well).
