SYNOPSIS
#include <Inventor/misc/SoContextHandler.h>
Detailed Description
The SoContextHandler class is for now to be treated as an internal
class.
- Since:
- Coin 2.0
- Public Member Functions
- typedef void ContextDestructionCB (uint32_t contextid, void *userdata)
- Static Public Member Functions
- static void destructingContext (uint32_t contextid)
static void addContextDestructionCallback (ContextDestructionCB *func,
void *closure)
- static void removeContextDestructionCallback (ContextDestructionCB
*func, void *closure)
Member Function Documentation
- void SoContextHandler::destructingContext (uint32_t contextid) [static]
- This method must be called by client code which destructs a context, to guarantee that there are no memory leaks upon context destruction.
- This will take care of correctly freeing context-bound resources, like OpenGL texture objects and display lists.
- Before calling this function, the context must be made current.
- Note that if you are using one of the standard GUI-binding libraries
from Systems in Motion, this is taken care of automatically for
contexts for canvases set up by SoQt, SoWin, etc. - References SbList< Type >::getArrayPtr(), and SbList< Type
>::getLength(). - void SoContextHandler::addContextDestructionCallback (ContextDestructionCB
- * func, void * closure) [static]
Add a callback which will be called every time a GL context is
destructed. The callback should delete all GL resources tied to that
context. - All nodes/classes that allocate GL resources should set up a callback
like this. Add the callback in the constructor of the node/class, and
remove it in the destructor. - See also:
removeContextDestructionCallback()
- void SoContextHandler::removeContextDestructionCallback
- (ContextDestructionCB * func, void * closure) [static] Remove a context destruction callback.
