The SoTabPlaneDragger class is a dragger you can translate and scale within a plane.
Here's how the dragger looks with its default geometry in the inactive state:
For translation, click anywhere inside the dragger's plane and move it about in 2D.
For non-uniform scaling operations, click and drag any of the 4 side tabs. For uniform scaling, click and drag any of the 4 corner tabs.
| SoTabPlaneDragger::SoTabPlaneDragger | ( | void | ) |
Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.
Nodekit structure (new entries versus parent class marked with arrow prefix):

Protected destructor.
(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)
Signals the dragger to recalculate the size of its tabs. This method is not doing anything useful in Coin, since the tab sizes are recalculated every time the dragger is rendered, even though this method has not been called.
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Called when user drags the mouse after picking the dragger.
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Called when mouse button is released after picking and interacting with the dragger.
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Called when dragger is selected (picked) by the user.

static |
Returns the nodekit catalog which defines the layout of this class' kit.
|
staticprotected |
Returns the pointer to the pointer of the nodekit catalog for this class.
This static method returns the SoType object associated with objects of this class.
|
protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.
Reimplemented from SoDragger.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Returns the SoFieldData class which holds information about fields in this node.
|
virtual |
Returns the nodekit catalog which defines the layout of this class' kit.

Not implemented.
|
protectedvirtual |
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.
Reimplemented from SoDragger.
Initializes type system for this dragger class.
Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init().
|
protected |
Recalculates the size of the tabs, based on the current view volume, the current viewport, the current model matrix and the current scale factor. If action == NULL, a default size will be used.
(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 SoDragger.

protectedvirtual |
Sets up all internal connections for instances of this class.
(This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.)
Reimplemented from SoInteractionKit.
| SoSFVec3f SoTabPlaneDragger::scaleFactor |
Continuously updated to contain the current vector of scaling along the X, Y and Z axes. The Z component will always be 1.0.
| SoSFVec3f SoTabPlaneDragger::translation |
Continuously updated to contain the current translation from the dragger's local origo position.
