orientation

Arguments: standard-object

Returns the value of the orientation property of the argument. This property applies to trackbar and up-down-control controls that can be placed vertically or horizontally, and to a printer, indicating the orientation of the image on the paper. The possible values for trackbars and up-down-controls are :horizontal and :vertical.

This property is not setfable. For a printer stream, it must be specified as the value of the :orientation initarg to open-stream when creating a printer stream (or by letting the end user specify it on the print job dialog that is invoked by default at that time). For trackbars and up-down-controls, the value must instead be specified with the inspector when designing a control (using a form) or with the :orientation 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.)

The possible values for a printer stream are :portrait and :landscape, where :portrait is taller than it is wide, and :landscape is wider than it is tall.

orientation is a property of the up-down-control, trackbar, and printer classes.
