Function documentation

TGLRect()
 Construct empty rect object, corner (0,0), width/height 0
TGLRect(Int_t x, Int_t y, Int_t width, Int_t height)
 Construct rect object, corner (x,y), dimensions 'width', 'height'
TGLRect(Int_t x, Int_t y, UInt_t width, UInt_t height)
 Construct rect object, corner (x,y), dimensions 'width', 'height'
~TGLRect()
 Destroy rect object
void Expand(Int_t x, Int_t y)
 Expand the rect to encompass point (x,y)
Int_t Diagonal() const
 Return the diagonal of the rectangle.
