class description - source file - inheritance tree (.pdf)
This is an abstract class, constructors will not be documented.
Look at the header to check for available constructors.

TGLDrawable
Abstract base class for all GL drawable objects - TGLPhysicalShape &
TGLLogicalShape hierarchy. Provides hooks for using the display list
cache in TGLDrawable::Draw() - the external draw method for all
shapes.
Defines pure virtual TGLDrawable::DirectDraw() which derived classes
must implement with actual GL drawing.
Display list caching can occur at either the physical or logical
level (with or without translation). Currently we cache only certain
derived logical shapes as not all logicals can respect the LOD draw
flag which is used in caching.
~TGLDrawable()
Destroy the GL drawable.
Bool_t SetCached(Bool_t cached)
Modify capture of draws into display list cache
kTRUE - capture, kFALSE direct draw
Return kTRUE is state changed, kFALSE if not
Bool_t ShouldCache(const TGLDrawFlags & /*flags*/) const
Returns kTRUE if draws should be display list cache
kFALSE otherwise
void Draw(const TGLDrawFlags & flags) const
Draw the GL drawable, using draw flags. If DL caching is enabled
(see SetCached) then attempt to draw from the cache, if not found
attempt to capture the draw - done by DirectDraw() - into a new cache entry.
If not cached just call DirectDraw() for normal non DL cached drawing.
void Purge()
Purge all entries for all LODs for this drawable from the display list cache.
Note: This does nothing at present as per drawable purging is not implemented
in TGLDisplayListCache.
