Here's how the dragger looks with it's 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.

Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry. Node kit structure (new entries versus parent class marked with arrow prefix):

(See SoBaseKit::printTable() for information about the output formatting.) |
|
Protected destructor. (Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.) |
|
Initializes type system for this dragger class. Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init(). Reimplemented from SoDragger. |
|
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. |
|
Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoDragger. |
|
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. |
|
(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.)
A virtual method that should call SoField::setDefault() with argument This is typically done when:
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. |
|
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. |
|
Not implemented. |
|
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. |
|
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. |
|
Continuously updated to contain the current translation from the dragger's local origo position. |
|
Continuously updated to contain the current vector of scaling along the X, Y and Z axes. The Z component will always be 1.0. |
