11.4. Dialog Boxes
Dialogs, like menus, can be either static or dynamic. The text strings in a dialog
can be localized by using string reference numbers instead of actual text.
Internally, dialogs are kept as a DIALOG structure that contain one or more
DIALOG_ITEMS structures at the end. Static dialogs are created with the
resource compiler and the data structures defining them reside in Flash. The only
routine that handles static dialogs is the
Dialog
function. Dynamic dialogs are
created with
DialogNew
and new fields can be added with
DialogAdd
. Dynamic
dialogs are executed with the
DialogDo
function. Dialogs use a call-back routine
to communicate with the caller as the user interacts with the dialog box.
Call-backs are explained later in section
11.4.4. Dialog Call-Backs
.
