class TGLManip: public TVirtualGLManip


 Abstract base class for viewer manipulators, which allow direct in
 viewer manipulation of a (TGlPhysicalShape) object - currently
 translation, scaling and rotation along/round objects local axes.
 See derived classes for these implementations.

 This class provides binding to the zero or one manipulated physical,
 hit testing (selection) for manipulator sub component (widget), and
 some common mouse action handling/tracking.

Function documentation

TGLManip& operator=(const TGLManip& )

 Assignement operator.

~TGLManip()

 Destroy manipulator object.

const UChar_t* ColorFor(UInt_t widget) const

 Returns color to be used for given widget.

Bool_t HandleButton(const Event_t& event, const TGLCamera& camera)

 Handle a mouse button event - return kTRUE if processed, kFALSE otherwise

Bool_t HandleMotion(const Event_t& event, const TGLCamera& camera)

 Handle a mouse button event - return kTRUE if widget selection change
 kFALSE otherwise

void CalcDrawScale(const TGLBoundingBox& box, const TGLCamera& camera, Double_t& base, TGLVector3* axis) const

 Calculates base and axis scale factor (in world units) for
 drawing manipulators with reasonable size range in current
 camera.

UInt_t GetSelectedWidget() const

{ return fSelectedWidget; }

void SetSelectedWidget(UInt_t s)

{ fSelectedWidget = s; }

Bool_t GetActive() const

{ return fActive; }

void SetActive(Bool_t a)

{ fActive = a; }

void Attach(TGLPhysicalShape* shape)

{ fShape = shape; }

TGLPhysicalShape * GetAttached() const

{ return fShape; }

void Draw(const TGLCamera& camera) const

 CRAPPY TVirtualGLManip TTTT, just override it here

Bool_t Select(const TGLCamera& , const TGLRect& , const TGLBoundingBox& )

{ return kFALSE; }
