> ## How to get the children of the instance

> You can get the children which the instance contains with the following method.

> The method | Description
> $instance_name->getChildInstance() | Returns the child by the instance name

> ### How to get the child by the specified name

> You can get the child by the specified name with the method: mpfc::WSCbase_getChildInstance();

>     use mpfc;

>     sub event_procedure {
>       my ($object) = @_;
>       # get the child which name is "newpbtn001"
>       $child = $object->getChildInstance("newpbtn001");
>       if ($child != 0){
>         # the child exists.
>         $child->setVisible($mpfc::True);
>       }
>       return;
>     }
>     1;

> In the example, mpfc::WSCbase_getChildInstance() seeks the child which name is "newpbtn001" from the instance: "object" recursively, and returns it if finds or returns NULL if not.
