Frame :accept-values panes are used when you want one of the panes of your application to be in the form of an accepting-values dialog.
There are several things to remember when using an :accept-values pane in your application frame:
For an :accept-values pane to work, your frame's command table must inherit from the accept-values-pane command table.
The :display-function option for an :accepting-values pane will typically be something like:
(clim:accept-values-pane-displayer
:displayer my-acceptor-function)
where
my-acceptor-function
is a function that you write. It contains calls to
accept
just as they would appear inside a
accepting-values
for a dialog. It takes two arguments, the frame and a stream.
my-acceptor-function
does not need to call
accepting-values
itself, since that is done automatically.
See Chapter 12, Menus and Dialogs especially the function accept-values-pane-displayer .
While inside the display function for an :accept-values pane, *application-frame* is not bound to your application. Instead, it is bound to an application that implements accepting-values . Therefore, you cannot use with-frame-state-variables in the display function for an :accept-values pane. Use with-slots on the frame argument instead.
Don't use : display-after-commands with :accept-values panes, because the redisplay for those panes is managed at a slightly lower level for efficiency.
