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.
~TGLManip()
Destroy manipulator object
void Select(const TGLCamera & camera)
Perform selection (hit testing) to find selected widget (component)
of the manipulator - stored in fSelectedWidget
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
Double_t CalcDrawScale(const TGLBoundingBox & box, const TGLCamera & camera) const
Calculates a scale factor (in world units) for drawing manipulators with
reasonable size range in current camera.
