NAME

      ActivateLayoutGadget -- Activate a gadget within a layout window.

SYNOPSIS

      Success = ActivateLayoutGadget( Gadget, Window, Request, Object )
d0 a0 a1 a2 d0
BOOL ActivateLayoutGadget( struct Gadget *, struct Window *,
struct Requester *, ULONG );

FUNCTION

      The equivalent of intuition.library ActivateGadget() for a
window controlled by layout.gadget. If successful, this means
that the user does not need to click in the gadget before
typing.
The gadget parameter MUST point to the root layout gadget in
the window, and the object parameter to the gagdet you wish
to activate. This works by calling the private
LAYOUT_ACTIVATEOBJECT method to search the layout hierarchy for
the specified gadget, and set the handleinput path to that
gadget, and finally calling ActivateGadget for the root object.
The rules of calling ActivateGadget() apply to
ActivateLayoutGadget() also.

INPUTS

      Gadget = pointer to the root layout obejct for the window.
Window = pointer to the window the gadget is in.
Requester = pointer to a requester (may be NULL)
Object = pointer to the BOOPSI object you wish to activate.

RESULT

      If the conditions above (and those of ActivateGadget()) are
met, the function will return TRUE, else FALSE.

NOTES

      Not only string gadgets can be activated this way. Many
ReAction gadget classes, such as the button.gadget, also
support keyboard control, and thus may be activated this way.
An attempt to activate a gadget that is not currently visible
(as on a hidden page) will fail.
