class TGLTransManip: public TGLManip


TGLTransManip

Translation manipulator - attaches to physical shape and draws local
 axes widgets with arrow heads. User can mouse over (turns yellow) and
L click/drag to translate along this axis.
 Widgets use standard 3D package axes colours: X red, Y green, Z blue.

Function documentation

TGLTransManip()

 Construct translation manipulator not bound to any physical shape.

TGLTransManip(TGLPhysicalShape * shape)

 Construct translation manipulator, attached to supplied TGLViewer
 'viewer', bound to TGLPhysicalShape 'shape'.

~TGLTransManip()

 Destory the translation manipulator

void Draw(const TGLCamera& camera) const

 Draw translation manipulator - tubes with arrow heads, in local axes of
 attached shape, in red(X), green(Y) and blue(Z), with white center sphere.
 If selected widget (mouse over) this is drawn in active colour (yellow).

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

 Handle mouse motion over manipulator - if active (selected
 widget) translate physical along selected widget (axis) of the
 manipulator, so it tracks mouse action. Returns kTRUE if redraw
 required kFALSE otherwise.
