Arguments: widget
Returns the value of the wrapping property of the argument.
wrapping is a
property of the up-down-control, static-text, button, default-button,
cancel-button,
radio-button,
and check-box
classes. The meaning is different for up-down-control than for the other
classes. The default value is t for static-text and
nil for the others.
The wrapping property cannot be modified on an existing control by calling (setf wrapping). Instead it must be specified by passing the :wrapping initarg to make-instance when creating the control. (When using the inspector to interactively edit controls on a form, the inspector can still make such modifications because it internally recreates the control's window to reflect the change and creates the make-instance form to create the control in tha ctaul applictaion.)
An up-down-control allows the user to
change the (typically) numeric value in an editable-text control by clicking
on an up arrow or a down arrow displayed on the up-down control. The
issue with wrapping is what happens when the
user clicks the up arrow when the value is at the top of the range or clicks the down
arrow when the value is at the bottom of the
range.
If the wrapping
property is true, clicking the up arrow when the value is at the top of the range changes the value to the bottom of
the range while
clicking the down arrow at the bottom changes the value to the top. If
wrapping is
nil, clicking an arrow when the value is at the extreme
of the range has
no effect.
If the wrapping
property on one of these controls is true (the default for static-text but not
for the others), the text (in the title of the various button
controls and the value of static-text controls) is
automatically wrapped at spaces as necessary to prevent the text from
extending beyond the right edge of the control. If nil, the text is displayed on a single line up to the
point where the text is clipped at the right edge of the
control. Turning this property off can be useful for a static-text
that displays only a single line of text so that a long word that
would otherwise be wrapped to the next (unseen) line will instead
remain on the first line to be visible up to the point where it is
clipped by the right edge of the control.
