static const enum TLine:: kLineNDC
A Graphical line
TLine(): TObject(), TAttLine()
Line default constructor.
TLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
:TObject(), TAttLine()
Line normal constructor.
~TLine()
Line default destructor.
TLine(const TLine &line) : TObject(line), TAttLine(line)
Line copy constructor.
void Copy(TObject &obj) const
Copy this line to line.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
Compute distance from point px,py to a line.
TLine* DrawLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
Draw this line with new coordinates.
TLine* DrawLineNDC(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
Draw this line with new coordinates in NDC.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
Execute action corresponding to one event.
This member function is called when a line is clicked with the locator
If Left button clicked on one of the line end points, this point
follows the cursor until button is released.
if Middle button clicked, the line is moved parallel to itself
until the button is released.
void ls(Option_t *) const
List this line with its attributes.
void Paint(Option_t *)
Paint this line with its current attributes.
void PaintLine(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
Draw this line with new coordinates.
void PaintLineNDC(Double_t u1, Double_t v1, Double_t u2, Double_t v2)
Draw this line with new coordinates in NDC.
void Print(Option_t *) const
Dump this line with its attributes.
void SavePrimitive(ofstream &out, Option_t *)
Save primitive as a C++ statement(s) on output stream out
void Streamer(TBuffer &R__b)
Stream an object of class TLine.
