B4J Question close form

[ziomorgan]

Hi,
when I close a form, its objects are initialized yet.
can i free all memory of a closed form?
(VB6 example: set myForm = nothing)
thanks

What do you mean with its objects? The nodes should be destroyed.

Yes.
I want to prove that the objects to be initialized the next time.
it is possible ?

My previous answer was not accurate. The nodes, like any other objects, will be destroyed when they are not referenced any more.

In almost all cases you should not be bothered about it. When you load the new layout the variables will point to the new nodes and the old ones will be destroyed.

You can use a class to manage the form. Then when you close the form you can remove the class instance reference and all the class objects will be released.

I understand the concept but I could use a small example to follow.
Can you show me?
