Arguments: up-down-control
Returns the name of the control to which the argument
up-down-control, which must be an up-down-control, is
attached. That control is called the buddy-widget. A typical buddy
widget is an editable-text control with a numeric
value. The value can be increased or decreased with the up-down
control (as well as typing directly into the text control).
See also the generic function up-down-control.
When designing a form with the IDE, a buddy-widget is connected to an
up-down control by clicking on the up-down-control, dragging it over
the desired buddy, and dropping it over either the left or the right
side of the buddy. A buddy control may be programmatically connected
by passing the name of the desired editable-text control as the value
of the :buddy-widget initarg when creating the up-down-control, and by
passing the name of the up-down-control as the value of the
:up-down-control initarg when creating the editable-text control.
Here are the possible value and their effects:
nil: the up-down-control is not connected to
another control.
editable-text control
with a companion up-down-control, the value of the buddy-widget
property for that up-down-control is the name of that editable-text control.
buddy-widget is a
property of the up-down-control class.
