Detailed Description

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.

See also: SoTabBoxDragger

SoTabPlaneDragger::~SoTabPlaneDragger ( void )

protectedvirtual

Protected destructor.

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

Member Function Documentation

SoType SoTabPlaneDragger::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoDragger.

const SoFieldData * SoTabPlaneDragger::getFieldData ( void ) const

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.

const SoNodekitCatalog * SoTabPlaneDragger::getNodekitCatalog ( void ) const

virtual

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

void SoTabPlaneDragger::adjustScaleTabSize ( void )

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.

void SoTabPlaneDragger::GLRender ( SoGLRenderAction * action )

protectedvirtual

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.

SbBool SoTabPlaneDragger::setUpConnections	(	SbBool	onoff,
		SbBool	doitalways = `FALSE`
	)

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.

void SoTabPlaneDragger::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 scenegraph 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's 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.

void SoTabPlaneDragger::reallyAdjustScaleTabSize ( SoGLRenderAction * action )

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.

void SoTabPlaneDragger::getXYScreenLengths	(	SbVec2f &	lengths,
		const SbMatrix &	localtoscreen,
		const SbVec2s &	winsize
	)

protected

Not implemented.

void SoTabPlaneDragger::dragStart ( void )

protected

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.

void SoTabPlaneDragger::drag ( void )

protected

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.

void SoTabPlaneDragger::dragFinish ( void )

protected

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.

Member Data Documentation

SoSFVec3f SoTabPlaneDragger::translation
