◆ ShouldDLCache()

Bool_t TGLLogicalShape::ShouldDLCache ( const TGLRnrCtx & rnrCtx ) const

virtualinherited

Returns kTRUE if draws should be display list cached kFALSE otherwise.

Here we check that: a) fScene is set (Scene manages link to GL-context); b) secondary selection is not in progress as different render-path is usually taken in this case.

Otherwise we return internal bool.

Override this in sub-class if different behaviour is required.
