class TGLManip: public TVirtualGLManip


TGLManip

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.
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()
{ return fSelectedWidget; }
void SetSelectedWidget(UInt_t s)
{ fSelectedWidget = s; }
Bool_t GetActive()
{ return fActive; }
void SetActive(Bool_t a)
{ fActive = a; }
void Attach(TGLPhysicalShape* shape)
{ fShape = shape; }
TGLPhysicalShape * GetAttached()
{ 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; }
