Constructor & Destructor Documentation

◆ TEveDigitSetGL() [1/2]

TEveDigitSetGL::TEveDigitSetGL ( const TEveDigitSetGL )
private

◆ TEveDigitSetGL() [2/2]

TEveDigitSetGL::TEveDigitSetGL ( )

Constructor.

Definition at line 29 of file TEveDigitSetGL.cxx.

◆ ~TEveDigitSetGL()

virtual TEveDigitSetGL::~TEveDigitSetGL ( )
inlinevirtual

Definition at line 37 of file TEveDigitSetGL.h.

Member Function Documentation

◆ AlwaysSecondarySelect()

virtual Bool_t TEveDigitSetGL::AlwaysSecondarySelect ( ) const
inlinevirtual

Reimplemented from TGLLogicalShape.

Definition at line 44 of file TEveDigitSetGL.h.

◆ DrawFrameIfNeeded()

void TEveDigitSetGL::DrawFrameIfNeeded ( TGLRnrCtx rnrCtx) const
protected

Make a decision if the frame should be drawn.

This depends on the render state (selection / highligt) and on values of members fSelectViaFrame and fHighlightFrame.

Definition at line 70 of file TEveDigitSetGL.cxx.

◆ DrawHighlight()

void TEveDigitSetGL::DrawHighlight ( TGLRnrCtx rnrCtx,
const TGLPhysicalShape pshp,
Int_t  lvl = -1 
) const
virtual

Draw the quad-set in highlight mode.

Incoming lvl is ignored – physical shape always calls it with -1.

Reimplemented from TGLLogicalShape.

Definition at line 94 of file TEveDigitSetGL.cxx.

◆ operator=()

TEveDigitSetGL& TEveDigitSetGL::operator= ( const TEveDigitSetGL )
private

◆ ProcessSelection()

void TEveDigitSetGL::ProcessSelection ( TGLRnrCtx rnrCtx,
TGLSelectRecord rec 
)
virtual

Processes secondary selection from TGLViewer.

Calls DigitSelected(Int_t) in the model object with index of selected point as the argument.

Reimplemented from TGLLogicalShape.

Definition at line 123 of file TEveDigitSetGL.cxx.

◆ SetBBox()

void TEveDigitSetGL::SetBBox ( )
virtual

Set bounding box.

Implements TGLObject.

Definition at line 85 of file TEveDigitSetGL.cxx.

◆ SetupColor()

Bool_t TEveDigitSetGL::SetupColor ( const TEveDigitSet::DigitBase_t q) const
protected

Set color for rendering of the specified digit.

Definition at line 37 of file TEveDigitSetGL.cxx.

◆ SupportsSecondarySelect()

virtual Bool_t TEveDigitSetGL::SupportsSecondarySelect ( ) const
inlinevirtual

Reimplemented from TGLLogicalShape.
