| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: trackbar
Returns the value of the tick-side property of the argument. The
possible values are :left
and
:top
(which, as we explain below, are equivalent),
:right
and :bottom
(also
equivalent), :both
, and :none
.
A trackbar can be oriented horizontally or vertically. Tick marks
provide a scale for the trackbar. Therefore :left
and :right
are appropriate for a vertical
orientation while :top
and
:bottom
are appropriate for a horizontal
orientation. However, to avoid errors when the orientation is changed,
if :left
is specified for a horizontal trackbar, it
is interpreted to mean :top
, and
:right
is interpreted to mean
:bottom
. Similarly, if :top
or
:bottom
is specified for a vertical trackbar, it is
interpreted as :left
or :right
respectively.
The trackbar pointer points toward the side with the ticks. If there are ticks on both sides, the pointer does not have a point (it is squared on both sides. If there are no ticks, the pointer points right or down.
The tick-frequency property determines the spacing of tick marks. See also tick-position.
The tick-side property may not be changed on an existing control, and must instead be specified with the inspector when designing a control (using a form) or with the :tick-side initarg of make-instance. (It can be changed using the inspector when designing a form but not for a running control, either in the IDE or in an application.)
tick-side is a
property of the trackbar
class.
This property is not supported by the simple GTK trackbar
widget, where it will have no effect.
