NAME
SoWindowElement -
The SoWindowElement class is used to store current window attributes.
In Coin, this element is not API-compatible with SGI Inventor, since it contains platform specific stuff, which we want to avoid.
SYNOPSIS
#include <Inventor/elements/SoWindowElement.h>
Inherits SoElement.

Detailed Description
The SoWindowElement class is used to store current window attributes.
In Coin, this element is not API-compatible with SGI Inventor, since it contains platform specific stuff, which we want to avoid.
Instead of the platform specific types we use void pointers. We're sorry for any inconvenience this might cause people using this element.
Constructor &; Destructor Documentation
SoWindowElement::~SoWindowElement (void) [protected], [virtual]
The destructor.
Member Function Documentation
SoType SoWindowElement::getClassTypeId (void) [static]
This static method returns the class type.
Reimplemented from SoElement.
int SoWindowElement::getClassStackIndex (void) [static]
This static method returns the state stack index for the class.
Reimplemented from SoElement.
void * SoWindowElement::createInstance (void) [static]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoWindowElement::initClass (void) [static]
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoElement.
void SoWindowElement::init (SoState *state) [virtual]
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState
objects.
Reimplemented from SoElement.
void SoWindowElement::push (SoState *state) [virtual]
This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using
SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.
Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and
the previous element can be found using SoElement::getNextInStack().
Reimplemented from SoElement.
void SoWindowElement::pop (SoState *state, const SoElement *prevTopElement) [virtual]
This method is callled when the state is popped, and the depth of the element is bigger than the current state depth. pop() is called on
the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.
Override this method if you need to copy some state information from the previous top of stack.
Reimplemented from SoElement.
SbBool SoWindowElement::matches (const SoElement *element) const [virtual]
This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.
If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.
Implements SoElement.
SoElement * SoWindowElement::copyMatchInfo (void) const [virtual]
This function creates a copy of the element that contains enough information to enable the matches() function to work.
Used to help with scenegraph traversal caching operations.
Implements SoElement.
void SoWindowElement::set (SoState *state, void *window, void *context, void *display, SoGLRenderAction *action) [static]
Sets data for this element.
void SoWindowElement::get (SoState *state, void *&window, void *&context, void *&display, SoGLRenderAction *&action) [static]
Returns data for this element.
Member Data Documentation
SoWindowElement::window [protected]
The window id.
SoWindowElement::context [protected]
The current context.
SoWindowElement::display [protected]
The current display.
SoWindowElement::glRenderAction [protected]
The current render action.
