Detailed Description

SoDragger is the base class for all nodekits you move by using the mouse to click-drag-and-release. More specifically, they are operated by a start (mouse button 1 pressed over dragger to pick it), followed by dragging (mouse motion events are interpreted by the dragger and result in some form of motion and/or change to a field), followed by finish (mouse up).

Each dragger has a different paradigm for interpreting mouse motion and changing its fields as a result. Draggers map 2D mouse motion into motion of a point on 3D lines, planes, spheres or cylinders. (See the SbProjector reference pages.) Then they react to this motion of a point through 3-space by scaling, translating, or rotating. For example, SoTranslate2Dragger maps mouse motion onto a 3D plane, then translates to follow the cursor as it moves within that plane.

Every dragger has fields that describe its current state. Scaling draggers have a scaleFactor field, rotational draggers have a rotation field, etc. All draggers have the isActive field, defined in this class. It is TRUE while the dragger is being dragged, FALSE otherwise.

Draggers that have only one part to pick and one motion field are called simple draggers. Examples are the SoRotateDiscDragger, SoScale1Dragger, and SoTranslate2Dragger.

Draggers that create assemblies out of other draggers and then orchestrate the motion of the whole assembly are call composite draggers. SoTransformBoxDragger is a composite dragger made entirely of simple draggers. SoDirectionalLightDragger contains both a simple dragger (SoRotateSphericalDragger) and a composite dragger (SoDragPointDragger) When using a composite dragger, the fields of the composite dragger are the ones you should work with. Draggers lower down in the assemblage usually have zeroed out values. For example, when you drag the face of a transformBox, an SoTranslate2Dragger, the transformBox "steals" the translation from the child dragger and transfers it up to the top of the composite dragger, where it effects all pieces of the assemblage.

Draggers always keep their fields up to date, including while they are being dragged. So you can use field-to-field connections and engines to connect dragger values to other parts of your scene graph.
Hence draggers can be easily utilized as input devices for mouse-driven 3D interface elements. You can also register value-changed callbacks, which are called whenever any of the fields is changed.

Also, if you set the field of a dragger through some method other than dragging, (by calling setValue(), for example), the dragger's internal SoFieldSensor will sense this and the dragger will move to satisfy that new value.

This makes it easy to constrain draggers to keep their fields within certain limits: if the limit is exceeded, just set it back to the exceeded maximum or minimum. You can do this even as the dragger is in use, by constraining the field value within a value-changed callback that you add with addValueChangedCallback(). In this case, be sure to temporarily disable the other value-changed callbacks using enableValueChangedCallbacks(). Doing this will prevent infinite-looping; changing the value followed by calling the callbacks which change the value ad infinitum.

When you drag a dragger, the dragger only moves itself. Draggers do not change the state or affect objects that follow in the scene graph. For example a dragger does not ever behave like an SoTransform and change the current transformation matrix. Draggers are not transforms, even if they have field names like translation, rotation, scaleFactor. Many draggers, such as SoTrackballDragger, have a corresponding SoTransformManip, in this case SoTrackballManip. The manipulator is a subclass of SoTransform, and affects other objects in the scene; it uses a trackball dragger to provide its user interface.
In this way, draggers are employed extensively by manipulators. Callback functions on the dragger allow its employer to be notified of start, motion, finish, and value changes. In all cases, the callback function is passed a pointer to the dragger which initiated the callback. (See the various man pages for more details on specific draggers and manipulators).

All draggers are nodekits. However, draggers do not list their parts in the Parts section of the reference page. Instead, there is a section called Dragger Resources, more suited to describe the parts made available to the programmer. Because of space limitations, the Dragger Resources section only appears in the online versions of the reference pages. Each dragger has some parts you can pick on, and other parts that replace them when they are active or moving. These active parts are often just the same geometry in another color.
Draggers also have pieces for displaying feedback. Each of these pieces has a default scene graph, as well as a special function within the dragger. Each part also has a resource name. All this information is contained in the DRAGGER RESOURCES section.

Since draggers are nodekits, you can set the parts in any instance of a dragger using setPart().

But draggers also give each part a resource name. When a dragger builds a part, it looks in the global dictionary for the node with that resourceName . By putting a new entry in the dictionary, you can override that default. The default part geometries are defined as resources for each class, and each class has a file you can change to alter the defaults. The files are listed in each dragger's man page. You can make your program use different default resources for the parts by copying the listed file from the directory /usr/share/data/draggerDefaults into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

otherEvent callbacks are called in response to events other than the standard button1Down, mouseMotion, and button1Up events. They are only called if the dragger has grabbed (which occurs only when button1 goes down and picks the dragger).

◆ addStartCallback()

Will return NULL if not possible. You must ref() and unref() this new path if you don't want it (and all the nodes along it) to stay around forever.

◆ enableValueChangedCallbacks()

bool SoDragger::enableValueChangedCallbacks ( bool  newVal)

The method returns a value that tells you if callbacks were already enabled. Use this method if you write a valueChanged callback of your own and you change one of the dragger's fields within the callback. (For example, when writing a callback to constrain your dragger). Disable first, then change the field, then re-enable the callbacks (if they were enabled to start with). All this prevents you from entering an infinite loop of changing values, calling callbacks which change values, etc.

◆ getMotionMatrix()

const SbMatrix& SoDragger::getMotionMatrix ( )

The motion matrix places the dragger relative to its parent space. (Generally, it is better to look in a dragger's fields to find out about its state. For example, looking at the 'translation' field of an SoTranslate1Dragger is easier than extracting the translation from its motion matrix.

◆ getNormalizedLocaterPosition()

SbVec2f SoDragger::getNormalizedLocaterPosition ( )
protected

2D locater positions have (0,0) at lower-left, and are relative to the viewport. Normalized positions go from 0.0 to 1.0. Regular positions go from 0 to (vpSize - 1)

◆ getPartToLocalMatrix()

void SoDragger::getPartToLocalMatrix ( const SbName partName,
SbMatrix partToLocalMatrix,
SbMatrix localToPartMatrix 
)

Good to use if transforms occur between 'motionMatrix' and the space you want to work in. Note: This routine will try not to create parts that don't exist. Instead it finds the existing part that precedes it in traversal. But this only works if the partName is in this nodekit's catalog. If the part is nested within another kit below this one or sitting inside a list part, the part will be created when it doesn't exist.

◆ setDefaultOnNonWritingFields()

virtual void SoDragger::setDefaultOnNonWritingFields ( )

Draggers don't want to write out fields if they have default vals.

sets isActive to default if default and not connected.

Looks for fields named: 'rotation' with value SbRotation::identity() 'translation' with value (0,0,0) 'center' with value (0,0,0) 'scaleFactor' with value (1,1,1) and sets them to default if they are not connected from a field. (most draggers are missing at least some of these, but thats okay)

Then calls the method for SoInteractionKit.

NOTE: Parts which are set to default may still wind up writing to file if, for example, they lie on a path.

First, the pickPath must contain the surrogatePath, indicating that the surrogate was picked. Second, we consider the part of the pickPath below the point where the surrogatePath ends. If this bottom section contains other draggers, then we will pass it up. This is because the other draggers will want to grab when they find out they've been picked.

◆ transferMotion()

void SoDragger::transferMotion ( SoDragger child)

void SoDragger::valueChanged ( )

These are invoked whenever setMotionMatrix() changes the motion matrix. If a subclass wishes to invoke the valueChanged callbacks for some other reason, they may call valueChanged(). Example: SoSpotLightDragger changes its angle field without altering the motionMatrix. So it calls valueChanged() to invoke callbacks.

◆ workFieldsIntoTransform()

void SoDragger::workFieldsIntoTransform ( SbMatrix mtx)

For instance, when called by an SoTranslate1Dragger, any rotations and scales in the matrix will remain unchanged. But the translation will be replaced with value in the 'translation' field. First, factor mtx to get values for the following: trans, rot, scale, scaleOrient. If there's a center field, send it to the factor method. Replace any of these four values if fields are found named 'translation' 'scaleFactor' 'rotation' and/or 'scaleOrientation' Note that this could be all or none of the 4 listed. Values for which no fields are found remain unchanged. Build a new matrix using the new values. Some may be the originals and some may have been replaced.

◆ workValuesIntoTransform()
