A class of window that is suitable for displaying controls (also
called widgets and dialog-items). Controls may actually be added to
any window, butdialogs are the only windows that
have special behavior for moving the keyboard focus among the
controls. This behavior includes pressing the TAB key to move to the
next widget, or pressing a letter key while holding down the ALT key
to move to the widget whose label underlines that character. (To be
precise, this behavior is defined on the non-instantiable dialog-mixin class,
and dialog is
the only built-in instantiable class that inherits this behavior.)
dialogs are
often shown modally by calling pop-up-modal-dialog. When this is
the purpose of a dialog, it is typically useful to specify the
pop-up property of the dialog as true. This
property coerces various other properties to their conventional values
for modal dialogs.dialogs are created by calling
make-window just
as other windows are.
An application can draw on a dialog just as it would on other
windows. Drawing that would intersect controls (or other child
windows) will not cover the controls, and instead will appear to be
covered by the controls.
See About how to get sample code for creating controls in cgide.htm, which explains how to use the IDE to create such code.
