.SH "Detailed Description"
.PP 
The \fBSoDirectionalLightDragger\fP class provides interactive geometry for manipulating a directional light source\&. 

Here's how the dragger looks with its default geometry in the inactive state:

.PP
  

.PP
This dragger is well suited to use for setting up the fields of a \fBSoDirectionalLight\fP node, as it provides geometry for the end-user to interact with a directional vector\&.

.PP
The image below is an action shot example, with the directional light being red and the camera headlight turned right down\&.

.PP
  

.PP
For convenience, this dragger also by default contains interaction geometry for placing the dragger itself\&. (\fBSoDirectionalLight\fP nodes don't have a position field, so this was strictly not needed\&.)

.PP
The Coin library also includes a manipulator class, \fBSoDirectionalLightManip\fP, which wraps the functionality provided by this class inside the necessary mechanisms for connecting it to \fBSoDirectionalLight\fP node instances in a scene graph\&.

Reimplemented from \fBSoInteractionKit\fP\&.

.PP
This is a virtual method, and the code in it should call \fBSoField::setDefault()\fP with argument \fRTRUE\fP on part fields that should not be written upon scene graph export operations\&.

.PP
This is typically done when:

.PP
.PD 0
.IP "1." 4
field value is \fRNULL\fP and part is \fRNULL\fP by default 

.PP

.IP "2." 4
it is a leaf \fBSoGroup\fP or \fBSoSeparator\fP node with no children 

.PP

.IP "3." 4
it is a leaf listpart with no children and an \fBSoGroup\fP or \fBSoSeparator\fP container 

.PP

.IP "4." 4
it is a non-leaf part and it is of \fBSoGroup\fP type and all fields are at their default values 

.PP

.PP

.PP
Subclasses should usually override this to do additional settings for new member fields\&. From the subclass, do remember to call "upwards" to your superclass' \fBsetDefaultOnNonWritingFields()\fP method\&.
