The CW_ORIENT function creates a compound widget that provides a means to interactively adjust the three-dimensional drawing transformation and resets the !P.T system variable field to reflect the changed orientation.
The returned value of this function is the widget ID of the newly-created orientation-adjustment widget.
This routine is written in the IDL language. Its source code can be found in the file
cw_orient.pro
in the
lib
subdirectory of the IDL distribution.
The widget ID returned by most compound widgets is actually the ID of the compound widget's base widget. This means that many keywords to the WIDGET_CONTROL and WIDGET_INFO routines that affect or return information on base widgets can be used with compound widgets.
See Compound Widgets for a more complete discussion of controlling compound widgets using WIDGET_CONTROL and WIDGET_INFO .
CW_ORIENT only returns events when the three dimensional drawing transformation has been altered. The !P.T system variable field is automatically updated to reflect the new orientation.
