I wonder if the mention of interface is the key. On LWM (at least), (capi:contain (make-instance 'capi:interface) :display-state :hidden) displays the interface on the screen. Perhaps the OP should pass the display-state argument to the make-instance and use capi:display: (capi:display (make-instance 'capi:interface :display-state :hidden)) Although I notice that capi:simple-pane-handle on the returned interface just returns -1. Maybe there's a more useful value on other systems. //JT On Fri, Sep 24, 2010 at 11:27 AM, Nick Levine <ndl@ravenbrook.com> wrote: > > That's odd.

1. From the docs on simple-pane-handle
"If pane is not displayed, or if pane does not have an underlying window, then handle is nil"
i.e., you must display the pane for simple-pane-handle to return a non-nil value.
2. not sure exactly what you're doing, but here's a simple example of how to have an interface with a pane that is hidden by default that you can display when you want (programmatically, etc.)
CL-USER 95 > (capi:define-interface my-interface () ()
(:panes
(text capi:text-input-pane :accessor my-text-pane))
(:default-initargs
:create-callback
(lambda (self)
(capi:hide-pane (my-text-pane self)))))
MY-INTERFACE
CL-USER 96 > (defparameter *my-interface-instance*
(capi:display (make-instance 'my-interface)))
*MY-INTERFACE-INSTANCE*
;; it is now displayed, but the text-input-pane is hidden
CL-USER 97 > (capi:show-pane (my-text-pane *my-interface-instance*))
#<CAPI:TEXT-INPUT-PANE TEXT 414015BE0B>
;; now it's shown
CL-USER 98 > (capi:hide-pane (my-text-pane *my-interface-instance*))
#<CAPI:TEXT-INPUT-PANE TEXT 414015BE0B>
;; now it's hidden again

See the documentation for how make-container uses the arguments: http://www.lispworks.com/documentation/lw60/CAPRM/html/capiref-213.htm > Although I notice that capi:simple-pane-handle on the returned > interface just returns -1. Maybe there's a more useful value on other > systems. That is because the Mac window system's top level interfaces are quite different from the panes inside them so capi:simple-pane-handle is not able to return anything useful. It returns a handle on other systems. > > //JT > > On Fri, Sep 24, 2010 at 11:27 AM, Nick Levine <ndl@ravenbrook.com> wrote: > > > > That's odd.
