The CW_ORIENT function creates a compound widget lets you interactively adjust the three-dimensional drawing transformation and resets the !P.T system variable field to reflect the changed orientation.
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.
Result = CW_ORIENT( Parent [, AX=degrees] [, AZ=degrees] [, /FRAME] [, TAB_MODE=value] [, TITLE=string] [, UNAME=string] [, UVALUE=value] [, XSIZE=width] [, YSIZE=height] )
This function returns the widget ID of the newly-created orientation-adjustment widget.
The widget ID of the parent widget.
The initial rotation in the X direction. The default is 30 degrees.
The initial rotation in the Z direction. The default is 30 degrees.
Set this keyword to draw a frame around the widget.
Set this keyword to one of the values shown in the table below to determine how the widget hierarchy can be navigated using the Tab key. The TAB_MODE setting is inherited by lower-level bases and child widgets unless it is explicitly set on an individual widget.
Note: It is not possible to tab to disabled (SENSITIVE=0) or hidden (MAP=0) widgets.
Valid settings are:
Disable navigation onto or off of the widget. This is the default. Child widgets automatically inherit the tab mode of the parent base as described in Inheriting the TAB_MODE Value.
Enable navigation onto and off of the widget.
Navigate only onto the widget.
Navigate only off of the widget.
Note: In widget applications on the UNIX platform, the Motif library controls what widgets are brought into and released from focus using tabbing. The TAB_MODE keyword value is always zero, and any attempt to change it is ignored when running a widget application on the UNIX platform. Tabbing behavior may vary significantly between UNIX platforms; do not rely on a particular behavior being duplicated on all UNIX systems.
The title of the widget.
Note: You can use language catalogs to internationalize this value with strings in particular languages.
Set this keyword to a string that can be used to identify the widget in your code. You can associate a name with each widget in a specific hierarchy, and then use that name to query the widget hierarchy and get the correct widget ID.
To query the widget hierarchy, use the WIDGET_INFO function with the FIND_BY_UNAME keyword. The UNAME should be unique to the widget hierarchy because the FIND_BY_UNAME keyword returns the ID of the first widget with the specified name.
The “user value” to be assigned to the widget.
Determines the width of the widget. The default is 100.
Determines the height of the widget. The default is 100.
Keywords to WIDGET_CONTROL and WIDGET_INFO
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 Creating a Compound Widget for a more complete discussion of controlling compound widgets using WIDGET_CONTROL and WIDGET_INFO.
Widget Events Returned by the CW_ORIENT Widget
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.
