In Coin, this element is not API-compatible with SGI Inventor, since it contains platform specific stuff, which we want to avoid\&. .PP Instead of the platform specific types we use void pointers\&. We're sorry for any inconvenience this might cause people using this element\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoWindowElement::~SoWindowElement (void )\fR [protected]\fP, \fR [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoWindowElement::getClassTypeId (void )\fR [static]\fP" This static method returns the \fBSoType\fP object associated with objects of this class\&. .SS "int SoWindowElement::getClassStackIndex (void )\fR [static]\fP" This static method returns the state stack index for the class\&. .SS "void * SoWindowElement::createInstance (void )\fR [static]\fP" \fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP .br .br Creates a new instance of the class type corresponding to the \fBSoType\fP object\&. .SS "void SoWindowElement::initClass (void )\fR [static]\fP" Initialize relevant common data for all instances, like the type system\&. .SS "void SoWindowElement::init (\fBSoState\fP * state)\fR [virtual]\fP" This function initializes the element type in the given \fBSoState\fP\&.

This happens when a writable element is requested, using \fBSoState::getElement()\fP or indirectly \fBSoElement::getElement()\fP, and the depth of the current element is less than the state depth\&. .PP Override this method if your element needs to copy data from the previous top of stack\&. The \fBpush()\fP method is called on the new element, and the previous element can be found using \fBSoElement::getNextInStack()\fP\&. .PP Reimplemented from \fBSoElement\fP\&. .SS "void SoWindowElement::pop (\fBSoState\fP * state, const \fBSoElement\fP * prevTopElement)\fR [virtual]\fP" This method is called when the state is popped, and the depth of the element is bigger than the current state depth\&. \fBpop()\fP is called on the new top of stack, and a pointer to the previous top of stack is passed in \fIprevTopElement\fP\&. .PP Override this method if you need to copy some state information from the previous top of stack\&. .PP Reimplemented from \fBSoElement\fP\&. .SS "SbBool SoWindowElement::matches (const \fBSoElement\fP * element) const\fR [virtual]\fP" This function returns \fRTRUE\fP is the element matches another element (of the same class), with respect to cache validity\&. .PP If the application programmer's extension element has a \fBmatches()\fP function, it should also have a \fBcopyMatchInfo()\fP function\&. .PP Implements \fBSoElement\fP\&. .SS "\fBSoElement\fP * SoWindowElement::copyMatchInfo (void ) const\fR [virtual]\fP" This function creates a copy of the element that contains enough information to enable the \fBmatches()\fP function to work\&. .PP Used to help with scene graph traversal caching operations\&. .PP Implements \fBSoElement\fP\&. .SS "void SoWindowElement::set (\fBSoState\fP * state, void * window, void * context, void * display, \fBSoGLRenderAction\fP * action)\fR [static]\fP" Sets data for this element\&. .SS "void SoWindowElement::get (\fBSoState\fP * state, void *& window, void *& context, void *& display, \fBSoGLRenderAction\fP *& action)\fR [static]\fP" Returns data for this element\&. .SH "Member Data Documentation" .PP .SS "void* SoWindowElement::window\fR [protected]\fP" The window id\&. .SS "void* SoWindowElement::context\fR [protected]\fP" The current context\&. .SS "void* SoWindowElement::display\fR [protected]\fP" The current display\&. .SS "\fBSoGLRenderAction\fP* SoWindowElement::glRenderAction\fR [protected]\fP" The current render action\&. .SH "Author" .PP Generated automatically by Doxygen for Coin from the source code\&.
