Detailed Description

The SoDragger class is the base class for all draggers.

Draggers is a mechanism used for letting the end-users of your application code interact with elements in 3D, by scaling, rotating or translating geometry or other instances in the scene (like cameras or light sources).

For a very thorough introduction and tutorial to the dragger classes and general concepts, we advise you to consult «The Inventor Mentor», ISBN 0-201-62495-8, chapter 15.

This is the common superclass for all dragger classes.

It holds the current motion matrix, and offers lots of convenience methods to build from for its subclasses – that is, the non-abstract dragger classes to use as nodes in your scene graph.

The motion matrix is used to modify the model matrix during traversal, and this is a common dragger mechanism – all draggers should update this during dragging.

A number of the Coin dragger classes have built-in convenience wrapper classes, called manipulators. See for instance the SoTrackballDragger / SoTrackballManip pair.

The matching manipulator class for any dragger class has basically two convenient additions to the functionality of the standalone dragger: 1) it makes swapping the dragger in and out of the scene graph very straightforward (something which is often done for draggers in 3D user interfaces), 2) it wraps up the dragger with SoSurroundScale and SoAntiSquish nodes where applicable, so the dragger geometry automatically scales up or down to match the geometry it influences.

This last functionality can also be duplicated in a rather straightforward manner outside of the context of a manipulator, as can be seen from the usage example in the SoSurroundScale class documentation.

The appearance of draggers can be modified by either using the SoDragger::setPart() method (see usage example below) or by setting up external Inventor-format files which the geometry parts are read from. The latter method can be done by setting the environment variable SO_DRAGGER_DIR to point to a directory with replacement geometry files. The name of the new files and the name of the nodes / sub-graphs with the replacement geometries must follow a rigid scheme. We advise you to look at the Coin source code directory Coin/data/draggerDefaults/ to see how the replacement geometry files should be named. Setting SO_DRAGGER_DIR to this directory and modifying the files there provides a convenient way to play around with new dragger geometry arrangements.

As mentioned above, SoDragger::setPart() can be used to modify the appearance of a dragger by changing its default geometry. One common technique is for instance to take advantage of this to use only parts of a dragger, by replacing / disabling the geometry that you don't want the end-user to interact with. The following code example shows how to remove the translation functionality of the SoTransformBoxDragger:

#include <Inventor/Qt/SoQt.h>
#include <Inventor/Qt/viewers/SoQtExaminerViewer.h>
#include <Inventor/draggers/SoTransformBoxDragger.h>
#include <Inventor/nodes/SoSeparator.h>
int
main(int argc, char ** argv)
{
  QWidget * window = SoQt::init(argv[0]);
  SoTransformBoxDragger * dragger = new SoTransformBoxDragger;
  SbString str;
  for (int i = 1; i <= 6; i++) {
    str.sprintf("translator%d.translator", i);
    dragger->setPart(str.getString(), new SoSeparator);
  }
  SoQtExaminerViewer * viewer = new SoQtExaminerViewer(window);
  viewer->setSceneGraph(dragger);
  viewer->show();
  SoQt::show(window);
  SoQt::mainLoop();
  delete viewer;
  return 0;
}

Draggers are also node kits, and below is the catalog structure for this top-level dragger class.

Nodekit structure (new entries versus parent class marked with arrow prefix):

CLASS SoDragger
-->"this"
      "callbackList"
      "topSeparator"
-->      "motionMatrix"
         "geomSeparator"

(See SoBaseKit::printDiagram() for information about the output formatting.)

Detailed information on catalog parts:

CLASS SoDragger
PVT   "this",  SoDragger  ---
      "callbackList",  SoNodeKitListPart [ SoCallback, SoEventCallback ]
PVT   "topSeparator",  SoSeparator  ---
PVT   "motionMatrix",  SoMatrixTransform  ---
PVT   "geomSeparator",  SoSeparator  ---

(See SoBaseKit::printTable() for information about the output formatting.)

Member Enumeration Documentation

◆ ProjectorFrontSetting

enum SoDragger::ProjectorFrontSetting

Holds various settings for projectors, which might affect cylindrical and spherical based draggers. Specifies whether dragging should be based on the front or back of the sphere / cylinder, or if the picked point should be used to decide this.

Enumerator
FRONT	Always use front of projector.
BACK	Always use back of projector.
USE_PICK	Use picked point to decide front or back of projector.

◆ callback()

void SoDragger::callback ( SoCallbackAction * action )

◆ setDefaultOnNonWritingFields()

void SoDragger::setDefaultOnNonWritingFields ( void )

protectedvirtual

(Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed are writing extensions, see the information in the SoBaseKit class documentation.)

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

This is typically done when:

field value is NULL and part is NULL by default
it is a leaf SoGroup or SoSeparator node with no children
it is a leaf listpart with no children and an SoGroup or SoSeparator container
it is a non-leaf part and it is of SoGroup type and all fields are at their default values

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

Reimplemented from SoInteractionKit.

Reimplemented in SoTransformerDragger, SoHandleBoxDragger, SoDragPointDragger, SoTransformBoxDragger, SoTrackballDragger, SoCenterballDragger, SoTabPlaneDragger, SoTabBoxDragger, SoSpotLightDragger, SoDirectionalLightDragger, SoJackDragger, and SoPointLightDragger.

◆ updateDraggerCache()

◆ getPickedPointForStart()

const SoPickedPoint * SoDragger::getPickedPointForStart ( SoHandleEventAction * action )

protectedvirtual

Interaction with the dragger will be started, if the returned picked point belongs to the dragger. A derived class can override this method to change the condition when the dragger starts interaction, e.g. it can return the picked point on the dragger from the picked point list of the action, even if it is covered by other (semi) transparent objects. The default implementation returns the foremost picked point from the action. This method is not present in Open Inventor.

Member Data Documentation

◆ isActive

SoSFBool SoDragger::isActive

Is TRUE whenever the user is interacting with the dragger. For compound draggers (draggers consisting of one or more subdraggers), the isActive field is updated only for the active subdragger, not for the compound dragger.
